# Merge Brain vs Coin Stack Puzzle

Merge Brain and Coin Stack Puzzle both sit at 4.7 stars, but that hides the real split: 54% of Merge Brain's written reviews are positive against 29% of Coin Stack Puzzle's. Coin Stack Puzzle's advantage is update cadence (weekly vs every 6 weeks) and ratings volume (3K vs 183). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Merge Brain sells 9 one-off in-app purchases and Coin Stack Puzzle sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Merge Brain against 4.7 for Coin Stack Puzzle. That said, the two scores are not equally well evidenced: Coin Stack Puzzle has 3K ratings behind it against 183, so its average is the more settled of the two. Written reviews are what separate them: 54% of Merge Brain's written reviews are positive against 29% of Coin Stack Puzzle's.
