Verdict
The clearest difference is in-app purchases: Sudoku # at none against ™ Sudoku's 1. Sudoku # also leads on update cadence (every 3 weeks vs every 8 months) and rating (4.7 vs 4.4). ™ Sudoku's advantage is ads (none vs shown) and iOS requirement (13.0 vs 16.0). On price, review sentiment and device support there is nothing between them.

Both are free to download. ™ Sudoku sells 1 one-off in-app purchase. Sudoku # asks for nothing beyond the download.
Sudoku # holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 121 and 395 respectively. Written reviews complicate that: 82% of ™ Sudoku's written reviews are positive against 79% of Sudoku #'s, so the app with the better star average is not the one people write more warmly about.
™ Sudoku ships an update every 8 months, Sudoku # every 3 weeks. The most recent releases landed on October 24, 2026 and October 26, 2026 respectively.
