# OLYM vs Ghost Castle Adventure

The clearest difference is in-app purchases: Ghost Castle Adventure at none against OLYM's 7. Ghost Castle Adventure also leads on ratings volume (409 vs 23). OLYM's advantage is update cadence (every 3 weeks vs every 7 months) and rating (4.0 vs 3.6). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. OLYM sells 7 one-off in-app purchases. Ghost Castle Adventure asks for nothing beyond the download.

OLYM holds the better App Store score, 4.0 against 3.6. That said, the two scores are not equally well evidenced: Ghost Castle Adventure has 409 ratings behind it against 23, so its average is the more settled of the two. Written reviews complicate that: 48% of OLYM's written reviews are positive against 55% of Ghost Castle Adventure's, so the app with the better star average is not the one people write more warmly about.

OLYM ships an update every 3 weeks, Ghost Castle Adventure every 7 months. The most recent releases landed on September 4, 2026 and September 13, 2026 respectively.
