Verdict

The call

⋆Sudoku and Sudoku both sit at 4.7 stars, but that hides the real split: 100% of Sudoku's written reviews are positive against 64% of ⋆Sudoku's. Sudoku also leads on ads (none vs shown) and update cadence (every 3 days vs monthly). ⋆Sudoku's advantage is ratings volume (161K vs 5). On price, rating, in-app purchases and device support there is nothing between them.
