A strategic game for 2 people. A richly varied three-dimensional game in which the players have to try to build geometric combinations with two-tone double blocks and at the same time tactically thwart the opponent's plans. Since a cuboid with the color of the opponent is automatically placed with each move, there are almost unlimited possibilities of combinations. For the first two moves in game 1 alone 1.400! There are 5 different ways to play: 1. game: Three blocks of the same color in a horizontal, vertical or diagonal combination of three. 2. game: Four squares of the same color in a vertical, horizontal or vertex combination of four. 3. game: Several horizontal, vertical or diagonal three-way combinations. 4. game: Several cuboids of the same color in a vertical, horizontal or vertex-combination of four. 5. game: Several vertical, horizontal and diagonal three-way combinations like game 1 and several vertical, horizontal and upside-down four-way combinations like game 4. —user summary
