Pyramid

From BoardGameGeek:

Bringing four of your stones to the top of the Pyramid doesn't seem like a big task. However, when your opponent has the same goal, you must outthink him. A stone has 3 options to move: RUN Move the stone forward as many fields as you want as long as his route does not go to a higher level. The stone cannot jump over other stones or share their field. If your stone moves to a lower level which is occupied by another stone, the attacked stone is SMASHED and gets removed from the game. JUMP Move the stone up to the unoccupied adjacent field one level above. PUSH Take the place of an adjacent stone by pushing it one field further. A pushed stone can also SMASH another stone. If the pushed stone was on a corner field at the lowest level, he FALLS and gets removed from the game. OSIRIS Apart from SMASHING and FALLING, stones can also be removed by forming an OSIRIS. If one or more stones of the same color get surrounded by the opposing color on the same level and in one line, they get removed. PYRAMID can end in two ways: The first player who positions 4 of his stones at the marked victory fields at the high level of the pyramid, wins the game and the glory of the Egyptian gods. When a player has only 3 stones left he automatically loses and the opposing player wins.
