# Sudøku vs Flying Penguin

The clearest difference is ads: Flying Penguin at none against Sudøku's shown. Sudøku's advantage is update cadence (every 4 days vs every 9 days) 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. Sudøku sells 1 one-off in-app purchase and Flying Penguin sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Sudøku ships an update every 4 days, Flying Penguin every 9 days. The most recent releases landed on September 24, 2026 and September 20, 2026 respectively.
