Space Mines is a game playable with Looney Pyramids -- one stash per player plus a few extras in a new color to be asteroids. The pieces are placed, lying on their sides, into the play space anywhere they fit -- there is no board or grid. Then the ships fire and mine in a prescribed fashion, targeting whatever is directly in front of them. Mining asteroids earns points, and those points can be doubled if you take the fewest losses.
