ChromaSquares is a puzzle game where the goal is to completely clear the board of colored squares. The color of each new square is randomly chosen from among the colors of squares already on the board. The only guarantee is that you won't get the same color twice in a row (unless that's the only color left).

The difficulty of the game can be changed by adjusting the number of colors in use and the dimensions of the game board. There is also an alternate color palette to assist colorblind players.
