The tower moves like a tower in chess, ie in any direction any number of fields (not obliquely). The first move is possible only by 1 field.
The towers have values. You can only take a tower that has the same or less value. When picking up the tower, the tower will lose a part of its power by 1 dot.
The goal of the game is to eliminate all opponents' towers.
A draw occurs at 3 times repeating the position.
