Verdict

The call

Sudoku· and Sudoku ▦ both sit at 4.7 stars, but that hides the real split: 62% of Sudoku·'s written reviews are positive against 38% of Sudoku ▦'s. Sudoku· also leads on monetization model (ad-supported vs free with in-app purchases) and iOS requirement (13 vs 15.0). Sudoku ▦'s advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (104K vs 17K). On price, rating, ads and in-app purchases there is nothing between them.
