# Hanoi Tower vs Screw Unlock

The clearest difference is update cadence: Screw Unlock at every 3 weeks against Hanoi Tower's every 7 months. Screw Unlock also leads on rating (4.8 vs 4.5) and review sentiment (44% vs 25%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Hanoi Tower sells 1 one-off in-app purchase and Screw Unlock sells 15 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
