# Kunai Master vs Stack Rush

The clearest difference is review sentiment: Kunai Master at 84% against Stack Rush's 33%. Kunai Master also leads on rating (4.9 vs 3.7) and ratings volume (6.6K vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Kunai Master sells 15 one-off in-app purchases and Stack Rush sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
