ReceptionRating · Positive reviews · Number of ratings

リバーシ Online holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Othello for all has 19 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 36% of Othello for all's written reviews are positive against 21% of リバーシ Online's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Othello for all ships an update every 3 months, リバーシ Online every 2 months. The most recent releases landed on October 26, 2026 and October 5, 2026 respectively.
