Mit Ach und Krach gibt's doch ein Dach

It's a rainy day in the woods. The imps (players) take turns to place their tokens onto the game board. The goal is to build a roof by occupying all three spaces that form a red or blue triangle. If a player completes a roof, he may remove an opponent token from the board. When all tokens are placed, the players move 1 token by one space each turn. To move between red and blue spaces is only possible via the greeen space in the center of the board. Any token moving onto the green space has to leave it next turn.

The first player who has only two tokens left, loses the game.
