Verdict

The call

The clearest difference is in-app purchases: Seadoku at none against Sudoku's 7. Seadoku also leads on update cadence (fortnightly vs every 3 months). Sudoku's advantage is iOS requirement (12.0 vs 18.0). On price, review sentiment, ads and device support there is nothing between them.
