Verdict

The call

The clearest difference is in-app purchases: Restore Number at none against Sudoku's 1. Restore Number also leads on iOS requirement (9.0 vs 12.0). Sudoku's advantage is ads (none vs shown) and update cadence (fortnightly vs every 6 weeks). On price, rating and device support there is nothing between them.
