# Sudoku vs PlusGrid

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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PlusGrid holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Sudoku has 222 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 72% of Sudoku's written reviews are positive against 100% of PlusGrid's.

Sudoku ships an update every 3 months, PlusGrid every 3 days. The most recent releases landed on November 1, 2026 and October 31, 2026 respectively.
