From the publisher: This is a two-player competitive game where players arrange blocks in a three-dimensional space and deduce the color and content combination of the "scoring condition" set by their opponent. Players aim to place blocks to fulfill their own scoring conditions and earn points. However, whenever you score points, you must give your opponent a hint about "which color block you scored with." Victory is achieved through this exchange of hints. You win immediately if you quickly figure out your opponent's scoring conditions or if you place blocks to fulfill all your own scoring conditions at once. If no winner is decided after four rounds, victory goes to the player with the higher total score. Additional notes: The basic game uses five colors of block and five scoring conditions (e.g. a color may score if it is standing, if it is on top of other blocks, etc.) The advanced game adds a sixth color and a sixth scoring condition.
