Verdict

The call

The clearest difference is in-app purchases: Sudoku· at none against Sudoku's 10. Sudoku· also leads on ratings volume (17K vs 1.1K) and iOS requirement (13 vs 15.6). Sudoku's advantage is ads (none vs shown) and review sentiment (95% vs 66%). On price, rating, update cadence and device support there is nothing between them.
