An Icehouse game in which players alternate turns playing pieces onto a 5 6 grid. Each piece must be played in the spot "pointed to" by the previous piece, and must point at an empty square. The first player unable to make a valid move, loses. Synapse-Ice was designed by Joseph Kisenwether and tied for 4th in the Winter 2005 Icehouse Game Design Competition. It was inspired by Pierre Berloquin's Le Synapse. The rules are available at icehousegames.org.
