Verdict

The call

The clearest difference is ads: Tectonic at none against Sudoku World's shown. Tectonic also leads on update cadence (every 2 months vs every 4 months) and iOS requirement (11.4 vs 15.6). Sudoku World's advantage is ratings volume (1.5K vs 39). On price, rating, review sentiment and in-app purchases there is nothing between them.
