Light Cross: free puzzle app game for ipad, iphone

Light Cross comes from http://keaton.com/apps/lightcross/en/

This type of puzzle has been done many times before under different names: Akari, Lighthouse, to name a couple.

Look at the first image. See the 2? you must place 2 lights on the adjacent sides. All cells must be illuminated. A light bulb cannot be in the path of another light bulb.


There are 40 free levels. I've done them all, very quickly. I particularly like the design of the boards: they are not necessarily squares.

I tried to purchase the 'Green Pack' of puzzle levels. But I don't think they're available yet.

'Can You Connect the Dots?' - free puzzle app game for iphone, ipad





'Can You Connect the Dots?' is the name of this point scoring free puzzle app game. Pradeep Chelani is the author.

To pass each level, you must score a certain number of points within a certain time.  The pink bar below keeps moving to the right as you score. The green bar keeps moving to the left as time expires.

On the Leaderboard, out of 2050 players, I'm at #16. However, I took a break after level 61. When I tried to continue, I had to restart. Had I not taken a break, who knows what my position would be?

Can You Connect the Dots? is not a totally original concept. But I was entertained.

Win at Sudoku

Caro Eardley recently contacted me about her book which teaches you how to solve Sudoku puzzles.

(I became a Sudoku fanatic back in 2001 when I went to Japan for the first time.  However, my enthusiasm has waned.)

Caro was kind enough to send me her book in pdf form. The diagrams are excellent. I have not read it yet, but I have skimmed it.

It's serious, thorough and could be the definitive text on the subject.  I plan to read it cover to cover next month.

http://www.amazon.com/Win-At-Sudoku-Christmas-ebook/dp/B004QX08FE/ref=sr_1_1?ie=UTF8&qid=1376221840&sr=8-1&keywords=Caro+Eardley

Colorooh comes from http://colorooh.digidingo.com/. They made Grooh last year, which I really liked.

Colorooh has 4 distinct puzzle games. The best one is Match-3. I don't like the title because it implies that it's similar to other 'match 3' point scoring puzzle apps.

Match -3: your objective is to swap 2 adjacent men so that: each Grooh-man is in a group of 3 or more. Look at the diagram: the yellow men must all be next to each other, because there are only 5 of them.

Now look at the red men: there are 9 of them. So, you can have them in 1 large cluster, or 2 or 3 clusters.

Each level: you are given 10 moves to make. If you win, the Grooh-men jump and dance with joy. If you lose, they weep and moan; and you realize you're a bad, mean puzzler.

Colorooh, has 3 other puzzle modes. The Shift Mode - this is not original. The Puzzle Mode - I have not explored this enough. It's a challenging set of topology problems. Too difficult to describe.  The Memory Mode tests your memory.

Without a doubt, the Match -3 Mode is the best and is an excellent, original concept.

Download Colorooh now!

Color Tower: free puzzle app game for iphone, ipad

 Color Tower comes from Tanu Kush.  The object is to unstack the tiles and restack them according to the master plan.
 There are 20 levels. I did the first 3 and the last 3. As a thinking puzzle, I'm not feeling the addiction. But Color Tower has gotten very good reviews lately. I wish the board could be rotated in order to tap those back cells.

Quantum Game: free physics puzzle app game for iphone, ipad

Bryan O'Neil from http://www.metalsgames.com/  recently contacted me about their new puzzle app game Quantum Game.

The object is to fire bouncing balls to ricochet off walls/obstacles to their targets.
Look at the center of the 2nd image.  See the circle that's half red/half white? That's where you fire from.  When you aim a red bouncing ball, another white ball will be fired from the same location in the opposite direction.

Hopefully, the red ball will hit the red circle and the white circle will reach its target.

There are 100 levels.  I've done 9 of them. Stuck on #10.

Did I mention that this a free puzzle app game? Unfortunately, you may be subjected to video ads.

If you like Angry Birds, give Quantum Game a shot.

'Push Box - Sokoban': puzzle app game for iphone, ipad

I got my first computer in 1994. It was a Gateway. I immediately bought a CD of games for $5. One of them was Box World. It had 100 levels of Sokoban - a new concept for me at the time. I did solve all of them. But I remember a few of them that took hours to solve. Specifically, #25, 35, 45. The program wouldn't let you skip a level either.

Rafael Martins recently contacted me about his new puzzle app game 'Push Box - Sokoban'.

'Push Box - Sokoban' has 240 new, original sokoban type puzzles. You can skip around the levels. Thanks Rafael! The puzzles are hard! Right now I've done 112 of them. It's going to be a long time before I complete them.

The graphics are pretty basic, but that's okay. Damn good puzzle app game.

Excellent job Rafael!

PicSanity: puzzle app game for kids

Samantha Zerman from Scrapple Labs recently contacted me about their picture game.  Strictly for kids. However, I did find myself playing it for a solid 30 minutes. Many of the answers are obviously simple - a child could figure it out in  a few seconds. But there were a few that I got stuck on.

Will PicSanity make the list of Best Puzzle Apps of 2013? Heaven's to Betsy - NO! But that's okay.

'Number Flow +' free puzzle app for iphone, ipad

About a week ago I saw a puzzle in the New York Daily News (a real newspaper) called Hidato. It had a somewhat funky grid with 126 boxes. I liked it enough to do a search on the App Store and found Number Flow +.

Number Flow + comes from Stanley Lam who has produced a lot of good puzzle apps recently, including Ripple Effect, which I also really liked.

The object in Number Flow + is to connect the numbers by 1 continuous path. The grid sizes are 6x6, 7x7, 8x8, 9x9 and 10x10. Each grid size includes 10 puzzle levels.  I've solved them all.

Number Flow + is absolutely fun, challenging and did I mention that it's free?  Download it!

HexConnect: puzzle app game for iphone, ipad

If you've been following this puzzle app blog, you know that I really like topology puzzle apps. As far as I know, this is the first one that uses a hexagonal grid. About a week ago Tamas Mile, who made HexConnect, sent me a promo code to play his game. Thanks!

HexConnect has 250 'Basic 1' levels and another 250 'Basic 2' levels.  I've done all of the Basic 2 levels. It took me 2 hours, 21 minutes and 28 seconds. I particularly like this time feature. I'm always amazed that people would refuse to pay 1 or 2 dollars for something that would entertain them for 2 hours. But they have no hesitation buying a soda for $2.50 that lasts 20 seconds. Or plunking down $10 to see a movie that may be awful.

HexConnect is not that hard because the hexagonal grid offers more freedom of movement.  Nevertheless, HexConnect is a winner! Feel free to read the list below. If I were you, I'd skip it and just download it.

Oh, I just discovered there's a Leaderboard connection. Of the 923 players, I'm ranked #2. The person who's ahead of me has a much higher score. I think he downloaded the additional levels. And he probably did all the Basic 1 levels.


Key Features
  • Highly detailed graphics: play in a nice high-tech feeling environment with sharp edges even on the highest resolution displays
  • Continuous level expansions: in addition to the two default level packs with a total of 500 levels, you get new free levels each week, and four new purchasable level packs with a total of 1000 levels each month!
  • Bonus levels: besides the weekly and monthly levels, you can get extra bonus levels in various ways!
  • Varying difficulty: the game offers a great variety of board shapes and difficulties to meet everyone's needs
  • Challenge: you can either go casual or strive for perfection and collect stars by completing levels with the least number of moves
  • Easy control and Convenience: you need only one finger to play the game
  • Fast game play: even if you have only a few minutes to play, you can pull up HexConnect and complete several levels
  • Game Center support: your progress is tracked on Game Center leaderboards and you are rewarded with over 20 great achievements for your accomplishments

Track by Track: free puzzle app game

Track by Track is a free puzzle app game from Georgy Sarkisyan. It's very similar to another puzzle app called Lazors.

The object is to move the brown/tan squares so the cannon will shoot the ball into the hole while passing through specific silver targets on the grid.

There are 60 levels. I did them all in a couple of hours - not continuously.  There's a good mixture of easy, medium & hard puzzles. I particularly like the levels that have 2 cannons.

Track by Track is fun!

101 Check Mate in 2 puzzles: free puzzle app for ipad, iphone

Natalie London recently published 101 Check Mate in 2 (moves) puzzles.

I was really looking forward to this - especially because it's a free puzzle app game. However, there were only 5 or 6 problems posed. To get access to the rest, you must pay $.99.

Oh well.

Rubik's Clock: free mechanical puzzle turned into puzzle app game for iphone, ipad

Oliver Klemenz has reproduced Rubik's Clock as a free puzzle app.

The object is to get all the clocks pointing to 12. There are 4 wheels on the sides to turn. In addition, there are 4 buttons to push. Also, the puzzle is dual sided.

Rubik's Clock is one of my favorite mechanical puzzles - not because it's hard - but because of its unique, clever design.

I believe I once saw a Rubik's Clock modification with 16 clock dials on each side. Would love to play with that.

Oliver - you've done well!

Zen Sand: physics puzzle app game for iphone, ipad

Antti Lehtinen recently contacted me about his physics puzzle app game: 'Zen Sand - The Most Relaxing of the Mind, Logic, and Brain Games.'  Quite a long title. You only need to type Zen Sand to find it.

Normally, I steer clear of the physics puzzle apps. But since Antti sent me a promo code to play it for free, I gave it a shot.  Could not stop!

Sand falls down the middle and you must direct it into the vases by drawing ramps.

See the pink lantern? When the sand goes through it, it will turn pink and then can be directed into the pink vase.

Other features: grinding wheels that make the sand finer. Fans to blow the sand up or sideways. Vases that are upside down.

There are 64 levels. I've done 53 and am now stuck.

Great job Antti!

SudoCross: puzzle app game for iphone, ipad

Are you into Sudoku? I first started playing it in 2001, when I attended the International Puzzle Party in Japan. A friend guided me to all of the Nikoli Press puzzle books.  I was hooked.

I have since, pretty much, stopped playing Sudoku - even though there are many terrific versions. My favorite is Squiggly Sudoku.

SudoCross comes from Shaun Patterson. SudoCross is a mixture of Sudoku and Crosswords. Each cell has a clue and the game offers 6 different types of clues when you tap on an empty cell. The clues are: digit, or, range, dot, plus and star.  I could go into explaining how they work, but it would be much faster for you to look it up.

SudoCross is a very serious, sophisticated version of Sudoku.

Gravitations: free physics puzzle app for ipad, iphone

 Gravitations is a free puzzle app game. The  object is to figure out a flight path that will go from 1 satellite to another, pick up a marooned astronaut and deal with fuel, gravity, black holes, worm holes etc.
 
I did all the Flight School levels. You can set up your own puzzles and post them for others to solve. Or, you can solve the puzzles that others have created.

Did I mention that Gravitations is free? Very cool puzzle app.

Marbly: free puzzle app game



Marbly comes from Andrey Novikov who made Tetris. The object is to move balls one at a time to create a row of 3 or more of the same color.

Each move must lead to a set of 3. You win when all the marbles have been eliminated.

I've solved all of the levels in volume 1. I think Marbly is quite good.

Finding Love: free puzzle app game for iphone, ipad

Finding Love is a free puzzle app game from Zhongsong Chen. It is not a dating site.

The object is to connect the rabbit to the other rabbit and do the same with the other creatures without crossing lines.

I did Chapter One, called 'I love you!' It has 15 levels.  I thought some of them were difficult.

Chapter 2 is called 'Get Full Version'.

http://blog.sina.com.cn/songsapp This is the homepage for Zhongsong. There, he calls the game Making Love.

Mathrax: free puzzle app game

Mathrax is very similar to KenKen. The object is to form a Latin Square: each row will have every number once. Same for the columns.

Look at the circle that says 5+ in the first diagram. means that squares which are diagonal will add up to that number.  So, in that little 2x2 square will be 4&1 on one diagonal and 3 & 2 on the other.

Look at the second diagram at the top left corner.  The zero is really the letter O. Which means that all 4 numbers will be odd.

Recently I reviewed another game from Stanley Lam: Ripple Effect.  Both of these are rock solid puzzle apps.

Move Dots: free puzzle app game for iphone, ipad

Move Dots is a free puzzle app game. It's classic in the sense that these types of puzzles have been posed for many years.  The directions are pretty simple.

Grab 2 adjacent dots and move them to an empty space. Then grab 2 more adjacent dots and keep doing this until the arrangement matches the image at the bottom.

There are 60 levels. I've done 15.

Did I mention that Move Dots is free?

90Blox Free: point scoring puzzle app for iphone, ipad

90Blox is a shooting game.  Shoot blocks into the grid from the right side, to form 3x3 squares or other rectangles.

You can move your gun up and down - just on the right side of the grid.  Tap with your left finger to rotate the grid.

Old school graphics.

It's okay.

Compulsive: free point scoring puzzle app for iphone, ipad

Compulsive is a very popular point scoring puzzle app. At this moment it has 119 5 star ratings and only 5 ratings lower than that. Impressive.

The object is to swap tiles anywhere on the board to create groups of 4 or more of the same color. They will disintegrate and score you points. Naturally, everything falls down and the results could lead to more groups of 4, thus setting off a chain reaction.

My top score is 140,900. This puts me somewhere in the top 15% according to the Leaderboard. The top scorer has 284,300. Not sure what his strategy is.

I like Compulsive, but I'm not feeling the addiction.

LightenUp: free puzzle app game for iphone, ipad



LightenUp is a free puzzle app from Dariusz Morawiec. No idea how to pronounce his name.

Look at the first image to get the rules.

 The first 40 puzzles are free. They are the size of the 2nd image.  I did them in about 15 minutes. The small grid sizes are perfect for people new to the genre.

The next 100 puzzles you have to pay for. They're bigger.
I've been doing this type of puzzle for years. Another name is Lighthouses. The best version is Akari 3D which takes this concept to a cube mode.

Matrix Sequence Free: puzzle app game for iphone & ipad

Are you good with sequences?  1, 3, 5 or 1, 5, 9? How about 2, 5, 8?  . Swipe sequences to score points.

You can also swipe four 7's if they're next to each other.

I've played this game for just over an hour (not all at once) and scored 115,000 or so.  The game is still going on because I'm not stuck.

I should mention: when you swipe a sequence, it will disappear and new numbers will fall down.

Interesting concept!

'Double View - The Hardest Brain Teaser Game': puzzle game app for iphone, ipad

'Double View - The Hardest Brain Teaser Game' is not the hardest anything. But it is challenging and fun.

You are given 2 mazes side by side. Swipe your man in any direction, keeping an eye on both at the same time to avoid the walls and pick up keys and then to reach the green target.

Double View - The Hardest Brain Teaser Game has 45 levels. I've done the first 25.  The third set has portals - I haven't been able to unlock that section yet. I really like this concept. I'd like to have the ability to adjust the speed slower for my advanced age.

Now for the annoying part: every time you complete a level or fail, you are given an ad.

THIS IS QUEENS: free app for the best borough in New York City

Hello Puzzle App Blog Followers:

THIS IS QUEENS, is a free puzzle app that highlights the best of Queens: the restaurants, museums, parks etc.



Want to visit the Steinway Piano factory? It's got all the details. Did I mention that the app is free?

If you're thinking of moving to NYC, Queens is the best bargain.

Make Me Blue: puzzle app game for iphone, ipad.

Freek Sanders recently contacted me about his puzzle app game Color Me Blue.  The object is to roll the pieces so that the top is blue. You do this by swiping a column or row. They all move at once.

There are 90 levels.  I've done the first 22 which fall under the categories: Kids, Beginner and Easy. The next batch are: Medium, Hard, Very Hard, Expert, Crazy and Impossible.


 
There are 2 other modes; I have not tested them.
Memory mode: see the blocks move and memorize the solution
Challenge mode: create your own puzzles and drive your friends crazy 


When I first played Make Me Blue, my initial thought was: reminds me of Head Spin, another puzzle app that I reviewed June 9, 2011.  Head Spin was just a 2x2 grid and the objective was to get the head face forward, right side up.  Damn good puzzle game. Unfortunately, it's no longer available on the App Store.

And that's okay, because Make Me Blue is essentially the same, but with more features.

Great job Freek!

Find The Mafia!: math puzzle app game for iphone, ipad

Adam Nagy recently contacted me about his new puzzle game app called Find The Mafia!

His note to me:

'The uniqueness of it is that it is based on a graph theory problem 'maximum clique problem', and maybe because of it its rules are extremely simple and elegant. (Yet it can be very challenging on higher levels.)'

Here is the website of the game (with video): http://experiware.com/ftm.html'
 
I wasn't sure exactly how it worked. I set the Mafia Size to 3 and then realized that I was essentially looking for a triangle - that is, the 3 people who all knew each other. Other people might know 1 or 2 of them but not all 3.
 
Look at the first diagram, can you see how the 4 people know each other and their lines equal/correspond to  the rectangle with diagonals?



Look at the second diagram. There are 16 people and 6 of them are 'made men'. I've tapped on 4 people. Their connections are highlighted in blue. See the red line? Those 2 people do not know each other. As you can see finding the 6 mafia men is very difficult.

In terms of originality, Find The Mafia! seems pretty unique. In terms of playing this game, I think it needs more pizzazz. More graphics would help. There was a game I reviewed not too long ago called Nun Attack. I didn't like that game, but I loved the title and images of nuns with guns and eye patches. That's what I think this game needs. Something outrageous.

Attention math teachers: show this game to your students!

One more thing: I highly recommend the Mario Puzo novel The Godfather.

Chainphoria: puzzle app game for iphone, ipad



Amir Michail recently contacted me about his new point scoring puzzle app: Chainphoria. The rules/objectives are not stated. They are for you to figure out. Like Vaccine Case and Deadlocked.

Chainphoria seems very similar to DropZap and DropZap 2. If you are fans of those, then I think this is up your alley.

Personally, I'm not a fan of DropZap, but I know lots of folks love them.  Chainphoria is a bit different. After playing it a few times and succeeding - I'm still not sure how or why I succeeded.

I think the graphics are very cool.

http://www.chainphoria.com/

7/22/14 update: Amir just contacted me about the rules. Cannot simplify them, so here they are!

http://www.chainphoria.com/rules

Chainphoria Simplified Game Rules

The following writeup omits some details but should give you a good idea of how to play Chainphoria. It is a work in progress. Please send feedback to a.michail@me.com 

Learn 1: Basics

  • Tap a column to make a move. All pieces in the selected column will become activated
  • An activated piece will attempt to activate a match with an adjacent piece based on color. 
  • When a match occurs, each piece involved in the match will: 
    • shrink (large to medium, medium to small, or small to nothing) 
    • become a targeted piece (if it is not already one) that 
      • wants to move to the selected column if it is not already there 
      • wants to move down (like an untargeted piece) if it is already in the selected column 
  • A targeted piece has two colors, one for matching, and another to indicate the column to which it wants to move. 
  • As a chain reaction proceeds, additional activation steps may occur. 
  • A piece that just moved in a particular direction will be activated if the piece in front of it along that direction did not also just move in that direction. 
  • A piece may be involved in more than one match in which case it will want to move to the column closest to it that contains an activated piece in one or more of those matches.

Learn 2: Recolor and Create

  • Learn 2 introduces recolored and created pieces.
  • A match may skip over a piece or a gap but not both.
    • Activating a match that skips over a piece will recolor the piece to the color of the match.
    • Activating a match that skips over a gap will create large circle(s) of the match color.

Learn 3: Followers

  • Learn 3 introduces piece following.
  • A targeted piece may at times follow an adjacent targeted piece provided that they are of the same color and want to go to the same column.
  • When a targeted piece is acting as a follower, it is shown without a diamond.
  • Following is done like this:
    1. follow piece above provided that it is not in the target column; otherwise
    2. follow piece above and left/right provided that it is a column closer to the target column; otherwise
    3. follow piece to left/right provided that it is a column closer to the target column; otherwise
    4. follow piece below and left/right provided that it is a column closer to the target column; otherwise
    5. follow piece below provided that it is in the target column

Standard

When you destroy (at least) 50 pieces, you will get a bonus based on the number of free slots in the grid after the chain reaction completes, all remaining pieces will be removed, the multiplier will be incremented, a new row will be inserted. 

Relentless

When you destroy (at least) 50 pieces, the multiplier will be incremented after the chain reaction completes but there will be no bonus and no pieces will be taken off the grid before a new row is inserted. 

Learn with a Friend

Two heads are better than one! Try any of the single player learn/game modes in a cooperative two player mode!

Space Dots: free puzzle app game for iphone, ipad

Space Dots comes from http://www.coragames.com/games.html  It's free and fun. Michael Contento is the author.

The rules of Space Dots are pretty simple: connect the squares in sequential order, and make sure your path covers all of the squares.

As you can see, there are 216 'Advanced' levels. I've done them all and all of the 216 Bonus levels. I also did the 216  6x6 collection. The vast majority of them I completed in under 20 seconds.

I really like these puzzles and always have. I think that Numeric Paranoia offers harder puzzles. But my perspective could be based on the fact that I've done hundreds, if not thousands of these. I did struggle on some of the Space Dots, but not many.

Numeric Paranoia costs money, while Space Dots is free.

The graphics of Space Dots are much nicer.

Stickets: puzzle app game for iphone, ipad

Several of this blog's followers urged me to look at Stickets by Harry Lee.

Look at the first image on the left. Your task is to place those 4 little pieces, one at a time, onto the grid to form regions which have 3 or more squares of the same color. When that happens, tap it to make it disappear.  This is not how to score points! You score 1 point for every shape that you fit inside.  That's it. When you can't fit another piece onto the board, you lose.

I'm extremely impressed with Stickets. Simple, fun, deep, frustrating. My high score is 137. And yet, I've also had very low scores of 15.

What I've just described is the Space mode.  It's the most fun. The Time mode is okay, but not my thing.

The Puzzle mode consists of some 8 or 9 very different puzzles - related to the Space mode. I've done half of them. I keep planning to solve the others, instead, I gravitate to the Space mode!

Stickets is a very smart, original, fun point scoring puzzle app. I'm very impressed.

Update 7/10/13: I've got my high score to 308 which places me 16th on the Leaderboard out of 4000. But I know I can do better. Must make my parents proud.  I feel the addiction!

Fizzy Factory: puzzle app game for iphone, ipad

Fizzy Factory is a puzzle app game from the good people at: http://hangzone.com/

If you're like me, you've done a few dozen laser game apps. Fizzy Factory is not quite the same thing. Yes, you must connect the red fountain to the red bottle - represented by the red soda cap. There are splitters, just like in laser games.

But the splitters work a little differently. For example, if a purple goes in, a red will come out of one hole and a blue will come out the other. However, if a red goes in, red will come out of both holes.

You can combine primary colors. However, mixing a red with a purple will yield brown. Brown cannot be split via the splitters into other colors. Just more brown will come out.

Fizzy Factory comes with about 200 free levels. I've done them all and collected 963 bottles.

A lot of them are easy. Way too easy. However, I struggled on a bunch. Fortunately, you can skip around and come back to it.

The bottom line: Fizzy Factory is fun!

There is a meta puzzle associated with Fizzy Factory. I did not play it, but here's the scoop: http://hangzone.com/the-fizzy-factory-secrof et-password-challenge/

Color Zen: puzzle app game for iphone, ipad

 Color Zen comes from Large Animal Games: http://www.largeanimal.com/support#!color-zen/c16nl

This is a hard game to describe. It's a cross between Flood-It and Vaccine Case. I know that I told you to download those! They are terrific with Vaccine Case being outstanding.

You must crash 2 shapes that have the same color. Then the entire screen will become that color. Keep doing this until the final color matches the border.

There are 120 levels. I've done all 120. 

Color Zen is challenging, fun and original. Easily: one of the Best Puzzle Apps of 2013.
