# Prisms vs Digital Sudoku ⊞

The clearest difference is in-app purchases: Digital Sudoku ⊞ at none against Prisms's 1. Digital Sudoku ⊞ also leads on update cadence (every 8 days vs every 17 months). Prisms's advantage is ads (none vs shown) and ratings volume (19 vs 2). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. Prisms sells 1 one-off in-app purchase. Digital Sudoku ⊞ asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Prisms against 5.0 for Digital Sudoku ⊞. That said, the two scores are not equally well evidenced: Prisms has 19 ratings behind it against 2, so its average is the more settled of the two.

Prisms ships an update every 17 months, Digital Sudoku ⊞ every 8 days. The most recent releases landed on October 11, 2026 and October 14, 2026 respectively.
