About
No time to overthink. 20 FLIP is speed reversi: 20 seconds per move.
— How to play —
Play fast rounds on a compact 6x6 board against the CPU, 20 seconds per move. Win and your streak grows as tougher CPUs step in. Lose, and you can watch a rewarded ad to retry with the same streak and the same opponent.
Beyond speed mode, the app also includes standard 8x8 reversi: play solo against the CPU, or pass-and-play with a friend on the same device.
— Who it's for —
• Quick brain breaks between tasks
• Reversi/Othello fans who want a faster pace
• Anyone chasing a longer win streak
• Friends or family playing pass-and-play
