# Sudoku vs CueQuanta

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

Both are free to download. Sudoku sells 4 one-off in-app purchases and CueQuanta sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Sudoku ships an update fortnightly, CueQuanta every 5 days. The most recent releases landed on October 31, 2026 and October 25, 2026 respectively.
