Similar to Jungle, the forerunner of Stratego.Each player has 13 animals, with strengths ranging from 1 to 13. The players move their animals orthogonally one space per turn and compare strengths between animals when one moves into an occupied space. The higher strength wins and captures the other animal, except in the case of the mouse (strength 1) which can capture an elephant (strength 13).There is a set of variant cards with the game which will offer some variety to the game by granting powers. - BoardGameGeek
