Verdict
The clearest difference is in-app purchases: Skill 15 at none against 15 Puzzle Challenge.'s 1. Skill 15 also leads on ads (none vs shown) and iOS requirement (8.0 vs 13.0). 15 Puzzle Challenge.'s advantage is ratings volume (1.4K vs 2) and update cadence (every 4 months vs every 19 months). On price, rating, review sentiment and device support there is nothing between them.

Both are free to download. 15 Puzzle Challenge. sells 1 one-off in-app purchase. Skill 15 asks for nothing beyond the download.
15 Puzzle Challenge. holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: 15 Puzzle Challenge. has 1.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 64% of 15 Puzzle Challenge.'s written reviews are positive against 71% of Skill 15's, so the app with the better star average is not the one people write more warmly about.
15 Puzzle Challenge. ships an update every 4 months, Skill 15 every 19 months. Both last shipped on October 21, 2026.
