# Sum 12 vs SUDOKUUU

The clearest difference is ads: SUDOKUUU at none against Sum 12's shown. SUDOKUUU also leads on update cadence (every 2 days vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Sum 12 sells 1 one-off in-app purchase and SUDOKUUU sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Sum 12 ships an update every 3 months, SUDOKUUU every 2 days. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
