Overturn – a Reversi game

CodeOn, s.r.o.

About this game

Place a disc, outflank a line, and watch it flip to your color. Overturn is the classic game of Reversi: simple rules, deep strategy, and one good move can turn the whole board over.

Every move must outflank at least one straight line of your opponent's discs, horizontally, vertically or diagonally, between the disc you place and one of yours. Every outflanked disc flips. No legal move? You pass. When neither side can move, the player with more discs wins.

AN OPPONENT WORTH YOUR TIME
• Three difficulty levels, from a gentle first game to an expert that counts the endgame down to the last disc
• Classic rules: four discs in the center, Black moves first, pass when you cannot move

THREE BOARDS IN ONE APP
• 8×8: the classic board
• 6×6: small, quick and sharp
• 10×10: the big board for long games

MADE TO BE PLAYED, NOT ENDURED
• A wooden board you actually want to look at, with discs that really turn over
• Or switch to Glass: a dark smoked-glass board with glass discs
• Legal moves shown on the board, take a move back, or rematch in a tap
• Replay any game move by move from your match history
• Pass & play on one device, or pick your side and take on the computer
• No ads. No account. Works offline.

Pull up a chair, take Black, and make the first move.
