Verdict

The call

The clearest difference is ads: PlusGrid at none against Sudoku's shown. PlusGrid also leads on update cadence (every 3 days vs every 3 months) and review sentiment (100% vs 72%). Sudoku's advantage is ratings volume (222 vs 1). On price, in-app purchases, device support and iOS requirement there is nothing between them.
