Känguru

35 cards (out of a total of 40) showing grassland or bushland are laid out in a 5x7-grid. Starting on one small side of the grid either one of the 2 players moves his kangaroo through the landscape eating the cards. Therefore he performs one of three actions on his turn: moving the kangaroo one grid, flipping the kangaroo card from a standing kangaroo to a sitting one or vice-versa or eating a card next to the kangaroo space. Grass will be eaten while the kangaroo is sitting and scoring 1 point, bush (2 points) is eaten while the kangaroo is standing. When all cards have been eaten the game ends and the winner is determined by the amount of points he scored.
This card game was handed out to every elementary school participant of the mathematical kangaroo competition 2011.
