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.

Goal

The first player to win four rounds wins the game.

Turn summary

On a turn, you take one stack and place it on another stack that is either

1. Same height
2. Same top symbol

Stacks cannot be divided.

End of the round

The round ends when one of the players cannot move anymore piles: this player has lost, and the other player wins the round.
