# Murder Sudoku vs Quiet Logic

The clearest difference is ads: Quiet Logic at none against Murder Sudoku's shown. Murder Sudoku's advantage is update cadence (every 5 days vs every 4 months) and iOS requirement (15.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Murder Sudoku sells 12 one-off in-app purchases and Quiet Logic sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Murder Sudoku ships an update every 5 days, Quiet Logic every 4 months. Both last shipped on October 31, 2026.
