Rainbow Grid: Logic Game

Rainbow Grid is a puzzle game where the goal is to make all of the tiles match the background colour in as few moves as possible.
When you press a tile, that tile and each tile next to it will iterate through a sequence of colours. You'll need a keen sense of logical reasoning to select the right tile at the right time and clear the grid.
With a randomly generated solution for each game, varying from 4-by-4 to 7-by-7 grids with a sequence of 2 - 7 colours, the combinations are endless!
