# ™ Sudoku vs Solid Sudoku

The clearest difference is rating: Solid Sudoku at 5.0 against ™ Sudoku's 4.4. Solid Sudoku also leads on update cadence (every 4 days vs every 8 months) and review sentiment (100% vs 82%). ™ Sudoku's advantage is ratings volume (121 vs 5) and iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ™ Sudoku sells 1 one-off in-app purchase and Solid Sudoku sells 2 in-app purchases, starting at $2.99 per year. Whichever you choose, the download price is not the number that matters.

Solid Sudoku holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: ™ Sudoku has 121 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 82% of ™ Sudoku's written reviews are positive against 100% of Solid Sudoku's.

™ Sudoku ships an update every 8 months, Solid Sudoku every 4 days. The most recent releases landed on November 11, 2026 and November 5, 2026 respectively.
