n-e-x-t is a Kindle puzzle game available from Amazon. It might be available for other platforms as well. The idea is that you can slide tiles around and whenever a tile touches a match, they disappear. In the spirit of ruining fun, this is a tool that can be used to solve the puzzles in the game. Please note that this may not actually work.
Enter the puzzle using the "puzzle" tab. Click a tile you want to change, and select a new tile from the menu. If you just want to see it work, you can use the default scenario.
Then click the solve button. Supposedly, you will then be shown a solution if one exists. It is likely that this is buggy.
