Verdict

The call

The clearest difference is ads: Icon Sudoku at none against Illuvium's shown. Icon Sudoku also leads on update cadence (every 2 days vs every 5 weeks). Illuvium's advantage is iOS requirement (12.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
