# Sudoku World vs Tectonic

The clearest difference is ads: Tectonic at none against Sudoku World's shown. Tectonic also leads on update cadence (every 2 months vs every 4 months) and iOS requirement (11.4 vs 15.6). Sudoku World's advantage is ratings volume (1.5K vs 39). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Sudoku World sells 1 one-off in-app purchase and Tectonic sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Sudoku World against 4.8 for Tectonic. That said, the two scores are not equally well evidenced: Sudoku World has 1.5K ratings behind it against 39, so its average is the more settled of the two. Written reviews are what separate them: 85% of Sudoku World's written reviews are positive against 82% of Tectonic's.

Sudoku World ships an update every 4 months, Tectonic every 2 months. Both last shipped on October 29, 2026.
