Soluna is a simple and fast-playing brain teaser for two players. The game consists of twelve double-sided discs; each disc has one of four space-themed symbols (sun, stars, moon, comet) on one side and a different symbol on the other side. At the start of play, the tiles are scattered on the table, creating twelve stacks that are each one tile high. On a turn, you take one stack and place it on another stack that is either (a) the same height or (b) topped by a tile with the same symbol. Stacks cannot be divided. Players take turns until one player cannot make a move; that player loses the game and the other player wins. Soluna is nearly identical to the earlier Bruno Faidutti game Babylon, but the double-sided discs create a new starting set-up for each round. The first player to win four rounds wins the game.
