Martian Coasters is a set of four colorful 4" beverage coasters, each featuring a small gameboard. Playing a game of Martian Coasters requires a Treehouse set and a standard six-sided die (not included). Each player has three pyramids of one color, which are distributed around the set of four coasters. The object is to move all of one's pyramids onto the coaster/gameboard of matching color and into a nested stack on the center of that board.
Arrows on the boards limit the directions in which a piece
may move; meanwhile, the distance each piece may travel is determined
by its size, and limited by the luck of the die rolls. Best of
all, each turn the Treehouse
die sets off a variety of actions on the gameboards themselves,
which include rotating the coasters, swapping pairs of coasters,
and even "hopping" a coaster to another edge, breaking
the universe out of its initial square configuration.
