# FlipFlop vs Sudoku

The clearest difference is rating: Sudoku at 4.8 against FlipFlop's 1.0. Sudoku also leads on in-app purchases (none vs 8) and update cadence (every 9 days vs every 7 months). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. FlipFlop sells 8 one-off in-app purchases. Sudoku asks for nothing beyond the download.

Sudoku holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: Sudoku has 703 ratings behind it against 1, so its average is the more settled of the two.

FlipFlop ships an update every 7 months, Sudoku every 9 days. The most recent releases landed on October 7, 2026 and October 24, 2026 respectively.
