# Sudoku vs Memory Maths

The clearest difference is ads: Memory Maths at none against Sudoku's shown. Memory Maths also leads on update cadence (weekly vs every 3 weeks). Sudoku's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.6). On price and in-app purchases there is nothing between them.

Both are free to download. Sudoku sells 3 in-app purchases, starting at $1.99 per 7 days and Memory Maths sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Sudoku ships an update every 3 weeks, Memory Maths weekly. The most recent releases landed on October 20, 2026 and October 19, 2026 respectively.
