Aim: You need to complete every row with matching colours.
The puzzle starts in the solved state, and you have to scramble it up and then solve it yourself.
Kerfuffle will remember where you got to each time you start playing, so you can take your time if you like.
Kerfuffle comes with two puzzles built in, one is a bit harder than the other because you have to also ensure that the pieces are all rotated in the same direction.
As you put your finger on a piece, the game will indicate available moves. Simply swipe the piece to where you want it to go.
The tricky part is that whenever you move one piece a few others will move as well!
Combine sequences of moves together to make small, predictable and useful changes to the puzzle.
Kerfuffle is unquestionably one of the hardest '2D Shift the Colors' type puzzle. This game cannot be done while watching the news or having a conversation. It demands your full attention.
If you solve it, come back and leave a comment and tell us how long it took and any thoughts you'd like to share.
More from Jeremy: Kerfuffle is completely isomorphic with the '3x3x3 Cube' twisty puzzle, same number of visible pieces, same algorithms, so it is certainly something to pay attention to while solving.
