Guroku Rainbow

The player moves colored stones around the game grid, which determines the directions in which a stone can move at a given position. His goal is to get the individual stones to the target square of the same color. Each time the player moves a stone in a chosen direction, that stone does not stop moving until it hits another stone or arrives at a position on the game grid from which it is no longer allowed to move in that direction. This principle forces players to devise clever solutions, such as strategically placing other stones in such places that the moving stone stops where it is needed.
