Rivoko

One stone. Four directions. A board that changes with every move. Rivoko is a turn-based strategy game played on a 5×5 board. Place a black or white stone and flip the first existing stone in each horizontal and vertical direction—even your own. Make a line of four or more to win, but look closely: your move can give your opponent the winning line. CLIMB THROUGH FIVE RIVALS Meet Nio, Kira, Bram, Vey and Nox. Earn unassisted wins to unlock the next rival, then win with both colors to master each challenge. PLAY TOGETHER Challenge a friend in local two-player mode on one iPhone. Take turns, switch colors for a rematch and review the game move by move. LEARN BY PLAYING Four interactive lessons introduce the rules. Preview the stones that will flip before you commit. Use hints and undo in solo training, then put what you learned into practice. PICK UP WHERE YOU LEFT OFF Matches, settings and achievements are saved on your device. Revisit completed games with a move-by-move replay. MADE FOR QUIET FOCUS Enjoy a tactile board, animated 3D rivals, light and dark themes, and English or German. Rivoko works entirely offline, with no accounts, ads or in-app purchases.
