Jumping Grid app for iPhone and iPad
You want to control the color grid movement, met with other colors and color absorption, when all colors are sucked on clearance. There are different provisions in the state to move in different colors: blue can only move left and right, red can only move up and down, but you can only move yellow, you want to find the right crisscross grid movement routes, beginning quite suited to understand the principles after the discovery kinda fun, but not simple.
