"Sackgasse" (=blind alley") was published in the German magazine Pöppel-Revue 1/86 as "Spiel im Heft".
The board shows a map of a fictive city with a muddle of streets. The streets are marked with large dots, who divide them in several sections.
Both players have only 3 tokens. They are brought into play under the "rule of distance": no token is allowed to be too near of another one, that is it must respect a minimal distance of 3 dots to any other token.
Each turn, a player must move his tokens by 6 dots in total, but he must attack at least 1 opposing token by placing a token on an adjacent dot. Therefore, a move will always begin with a retreat of the attacked token. If it's not possible to reestablish the rule of distance for that token, it is eliminated.
Winner of the game is the player who eliminates 2 opposing tokens first.
