Red 10 app for iPhone and iPad

Red 10 is a challenging number puzzle game.
The goal of the game is to join the tiles to get to the Red 10 tile.
The tiles can be moved in one direction (up, down, left or right).
If a tile moves toward another tile of the same color, these tiles can merge into new one that is the sum of their values.
If the sum exceeds 10, the tile changes the color and its number restarts from 1.
The blue tiles can become azure, then green, lime, yellow, orange and finally red.
Attention: two red tiles cannot merge if their sum exceeds 10 (Red 10 is the highest tile in the game).
