'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!
