Sol

From the game's back cover: "Since mankind discovered that the stars are actually suns not much unlike our own, we have wondered what mysterious worlds might orbit these distant balls of light."

Sol is a combinatorial tile-laying game by David Mines in which two players try to control a majority of sun tiles at the end of the game. Control of each sun is determined by who controls the majority of its adjacent planets, with ties broken by the player who played the sun tile. Control of each planet is, in turn, determined by who controls the majority of its adjacent moons, with ties again broken by the player who played the planet.

The player who controls the most suns at the end of the game wins.
