# Rainbow Snake! vs Worm Stack

The clearest difference is rating: Worm Stack at 4.7 against Rainbow Snake!'s 3.4. Worm Stack also leads on update cadence (every 2 weeks vs every 3 months) and ratings volume (1.7K vs 8). Rainbow Snake!'s advantage is in-app purchases (none vs 12). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Worm Stack sells 12 one-off in-app purchases. Rainbow Snake! asks for nothing beyond the download.

Worm Stack holds the better App Store score, 4.7 against 3.4. That said, the two scores are not equally well evidenced: Worm Stack has 1.7K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 60% of Rainbow Snake!'s written reviews are positive against 52% of Worm Stack's, so the app with the better star average is not the one people write more warmly about.

Rainbow Snake! ships an update every 3 months, Worm Stack every 2 weeks. The most recent releases landed on September 20, 2026 and October 1, 2026 respectively.
