Verdict

The call

The clearest difference is ads: Infinity Sudoku 9x9 at none against Mars's shown. Infinity Sudoku 9x9 also leads on review sentiment (100% vs 91%). Mars's advantage is ratings volume (22K vs 2) and iOS requirement (12.0 vs 16.0). On price, rating, update cadence and in-app purchases there is nothing between them.
