Swap tiles around in this 4 x 4 grid-based puzzle game to fill the centre 2 x 2 square with the right colours.
At the start of each turn, one paint droplet will appear randomly around the grid and will mix with the tile right in front of it at the end of your turn. Strategically move tiles around to mix the right colours so that you fill the centre goal area with 4 tiles of the same colour 10 times, each time with a different colour out of the 10 available. But watch out, if any more paint mixes with a black tile, its game over!
