Reversi starts with four discs in the center of an 8×8 board. Dark moves first. A legal placement brackets opposing discs in one or more of eight directions, and the bracketed lines flip from that move.
Play as Dark against the computer, which plays Light, or choose local two-player mode on one device. When a side has no legal move its turn passes; the match ends when neither side can move. Matches are not saved.
Reversi is a single-board match rather than a level campaign. Choose computer mode, where you are Dark and the computer is Light, or local two-player mode on one device.
A player with no legal move automatically passes. When neither player can move, the match ends even if some squares are empty; the side with more discs wins, and an equal count is a draw.
Before placing a disc, look for every straight line it could bracket. One placement can flip opposing discs along multiple directions at the same time.
A corner cannot be bracketed from beyond the board. Consider whether an available move near a corner could give the opponent access to it.
Compare the moves each side will have after a placement. Flipping more discs immediately is not the only way to improve a position.
If the other player has no legal placement, their turn is skipped automatically and play continues with the player who can move.
When neither player has a legal move, the game ends and only the Dark and Light discs on the board are counted. More discs wins; equal counts are a draw.
There is no online multiplayer. Choose the computer opponent or local two-player mode on the same device.
No. Matches are not saved. Restarting or switching modes begins a fresh game.
If the side to move has no legal placement, its turn is skipped. The other side continues if it can move.
Yes. When neither side has a legal move, the game ends and only the discs on the board are counted. Empty squares do not belong to either side.
It returns to the start of your previous turn and removes all computer replies before your next turn, including consecutive computer moves after an automatic pass.
