Rox is a unique game for the GameBoy Color that combines elements of falling blocks and matching games. In Rox, each block represents a dice with a number on it. The twist in this game is that both the numbers and colors of the dice matter when it comes to removing them.
To remove two end dice, their numbers must be the same, and there must be an equal number of other dice between them. For example, if two dice are ones, there should be one die in between them. If both end dice have the same color, all the dice in between will be erased. However, if the end dice have different colors, only they will be removed.
