We reviewed and enjoyed the first release of Kris Pixton's PathPix back in June.
PathPix is a simple puzzle game that has you drawing lines to connect numbers. The iPhone version of the game is based on the PC version of the same name but also resembles Link-a-Pix (Web) and Pic Pic's Drawing mode (Nintendo DS). The rules are simple:
Draw paths with your finger, connecting pairs of colored numbers. The length of each path must match the numbers on the two endpoints. Draw backwards or double tap to correct mistakes. There's only one way to do it, and all squares will contain a piece of a path when the puzzle is solved.
The original version of the game came with 144 levels which would have offered a fair amount of gameplay though PathPix addicts were soon asking for more.
Pixton has appeased those individuals with a new Pro version for experienced players. For $2.99, you can get 300 more levels ranging form Medium to Extreme difficulty. We really enjoyed this game and found ourselves quickly immersed in the gameplay. If you've never played it, give the Lite a try as we highly recommend it.
