Go for 1st place or just avoid last — your strategy is your own. ■ Rules ① The basic rules are just like traditional Othello: players take turns placing stones and flip the opponent’s stones when sandwiching them. ② When the board is full, rankings from 1st to 4th are determined by who has the most stones. ③ If you can't make a valid move, you can place a stone on any empty space adjacent to an opponent’s piece. ■ Online Play ・Battle real-time with players around the world! ・Share a room code to easily play with friends. ・If fewer than four players join, CPU players will automatically fill in. Fully free to play — no hidden fees!

Verdict
The clearest difference is ads: 壁リバーシ at none against 4's shown. 4's advantage is update cadence (every 2 months vs every 19 months) and iOS requirement (12.0 vs 14.0). On price, in-app purchases and device support there is nothing between them.
