Equinox is an abstract tile-placement game with 48 different two-sided hexagonal tiles named things such as Night, Day, Sword, Tower; these tiles have a white side and black side that are otherwise identical.

One player plays as black and the other as white. They take turns playing tiles from a common pool until all have been played. Each tile has a unique action that affects the tiles around it, the score, or some other gameplay element. At the end of the game, each player scores points for the tiles showing their side, plus any bonus point tokens they have earned.

Win by having the highest score!
