  1. Place the black coaster in the center of the table, and place each coloured coaster adjacent to one side, forming a cross.
  2. Create five three-colour trees, and place each on a coaster of a colour not included in the tree.


  1. Assign two transparent colours to each player, leaving the opaque black (or white, if using Xeno pieces) unassigned.
    • "Warms" vs. "cools" is an intuitive grouping for Rainbow pieces.
  2. Play proceeds as in two-player Martian Coasters, with each player attempting to complete both of their nests.

The "8-Ball"

The black nest is the "8-Ball". As in billiards, the 8-ball cannot be scored until the scoring player has completed his other objectives.

  • No player may complete the black nest until both of his coloured nests are completed. Any player doing so forfeits any remaining movement points or special actions and loses immediately.
  • A player may not directly move any black pieces until he has completed at least one coloured nest.
    • Black pieces do not prevent aim, hop, or dig actions affecting them indirectly.
    • Black pieces do not prevent moving a piece from below them to the top of their stack using movement points.


  • A player wins when both of his nests are completed, and he completes the black nest.
  • As implied by the name, a player may not complete the black nest until both of his coloured nests are completed. Completing the black nest prematurely results in a loss for that player.


  • Two-handed play can be sped along by limiting each player to one colour.
  • This game could be expanded to three- or four-handed play by limiting each player to one colour.
