# Puzzle Clock vs Rubik Master

The clearest difference is update cadence: Rubik Master at every 4 days against Puzzle Clock's every 4 months. Rubik Master also leads on rating (4.5 vs 4.1) and ratings volume (297 vs 21). Puzzle Clock's advantage is review sentiment (75% vs 48%) and monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Puzzle Clock sells 4 one-off in-app purchases and Rubik Master sells 2 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Rubik Master holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Rubik Master has 297 ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 75% of Puzzle Clock's written reviews are positive against 48% of Rubik Master's, so the app with the better star average is not the one people write more warmly about.

Puzzle Clock ships an update every 4 months, Rubik Master every 4 days. The most recent releases landed on September 6, 2026 and September 21, 2026 respectively.
