Reversi, played among the stars.

The rules are the ones you already know. Trap a line of your opponent's discs between two of yours and the whole line turns over. Whoever holds the most when no moves remain wins. A game takes only a few minutes.

What is different is what happens while you play.

EVERY DISC YOU TURN OVER EARNS STARDUST

Not wins—captures. A long game that goes the wrong way still pays, because a close match you lost was still a match worth playing. A harder opponent pays more for the same game.

Stardust buys the surface the board is cut from, the stone it sits on, the discs themselves, the sky behind it, the way the pieces move, and the music. Nine worlds to play in, from Earth and the Moon to a hot rod's space station and a haunted Hallow's Eve.

EIGHT CONSTELLATIONS, HIDDEN IN PLAIN SIGHT

Six items make a set, and nothing tells you which six. The descriptions are the clues. Find every piece of a look and it names itself—Blockworld, Moonfall, Deep Nebula, the Trophy Room—and the board starts behaving like the place it came from.

The Trophy Room cannot be bought at all. Its six pieces are handed over one at a time by six different achievements, and the last of them arrives only when you own everything else.

TWO PLAYERS, ONE PHONE

Play a friend in Pass & Play—make your move, hand the phone over—or lay it flat between you in Table-Top, where each end of the screen faces the player sitting there. Nothing to set up, nothing to sign in to, and no ads between two-player games.

A BOARD THAT REACTS

Turn four discs at once and a comet crosses the sky. Turn five and the fireworks start, growing larger the more you capture. You probably shouldn't touch those.

Win, and the whole board slams over from your side and shows you a face.

HONEST ABOUT MONEY

Nothing in the game has to be bought. The Stardust Shop takes only the currency you earn by turning over your opponent's discs: no Stardust packs, no premium currency, and every cosmetic is earned by playing.

If you'd like to support the studio, the optional Supporter upgrade removes the ads and adds 50% more Stardust to every match. Everything it speeds up, you can still earn without it.
