The game is based on the idea of merging tiles to receive the higher value. Instead of tiles, you move Pyramids in this game. Each pyramid has 4 sides (walls), and every side has its value (2, 4,...). When some pyramid appears next to another pyramid, and their contacting sides have equal values, you may "merge" these sides-values. Click on pyramid to merge values of two contacting sides (2 + 2 = 4), and the resulting value will appear on the side of the pyramid. Game starts with values of 2. To win the game, you must reach the value of 64. When you receive the next higher value, the strip-show raise to the next level.
