# Camp Mahjong vs Screw Master

Camp Mahjong and Screw Master both sit at 4.7 stars, but that hides the real split: 100% of Camp Mahjong's written reviews are positive against 30% of Screw Master's. Camp Mahjong also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Screw Master's advantage is ratings volume (11K vs 134) and update cadence (fortnightly vs every 2 months). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Screw Master holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Screw Master has 11K ratings behind it against 134, so its average is the more settled of the two. Written reviews complicate that: 100% of Camp Mahjong's written reviews are positive against 30% of Screw Master's, so the app with the better star average is not the one people write more warmly about.

Camp Mahjong ships an update every 2 months, Screw Master fortnightly. The most recent releases landed on November 7, 2026 and November 9, 2026 respectively.
