The object of the game is to fill the entire board with a single color in a given number of moves. The board is made up of several colored squares and the player starts by choosing a color from one of the squares. All adjacent squares with the same color are then filled with the new chosen color. The player must keep choosing new colors to fill as many adjacent squares as possible with the new chosen color.

The maximum number of allowed moves varies according to the size of the board and the difficulty level chosen by the player. The bigger the board and the harder the level, the fewer moves allowed to complete the game.

Color Flood is a fun and challenging game that requires strategic thinking and problem solving skills to determine the best sequence of colors to choose to fill the entire board with a single color.
