# Reverse vs Euler Sudoku

The clearest difference is in-app purchases: Euler Sudoku at none against Reverse's 1. Euler Sudoku also leads on ads (none vs shown) and update cadence (weekly vs every 3 weeks). Reverse's advantage is rating (5.0 vs 4.8). On price and device support there is nothing between them.

Both are free to download. Reverse sells 1 one-off in-app purchase. Euler Sudoku asks for nothing beyond the download.

Reverse holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Euler Sudoku has 5 ratings behind it against 1, so its average is the more settled of the two.

Reverse ships an update every 3 weeks, Euler Sudoku weekly. The most recent releases landed on October 24, 2026 and October 12, 2026 respectively.
