Three Exciting Game Modes! [VS CPU] Challenge a tough CPU opponent with five difficulty levels! ▼ How Turn Order is Decided At the start of the game, toss an Othello piece to determine who goes first. Black moves first, and White moves second. [VS 2P] Play a face-to-face match on a single device! [VS ONLINE] Enjoy online battles with randomly matched opponents! Each player has a total of 3 minutes, with a countdown running during their turn. ▼ What happens if you run out of time? A piece will be placed randomly in an available spot! However, from the next move onward, you can still place a piece manually within 3 seconds. *Rating and ranking features coming soon!

Verdict
The clearest difference is in-app purchases: オセロ練習用 at none against Reversi Effect's 3. オセロ練習用 also leads on ads (none vs shown). Reversi Effect's advantage is update cadence (every 5 days vs monthly) and iOS requirement (13.0 vs 17.6). On price and device support there is nothing between them.
