A large headline number does not automatically make a casino's game library useful. The better test is whether the catalogue contains the categories, providers and navigation tools that make games easy to find and understand.
Check category coverage Look for a useful mix of slots, table games, live casino and any other sections the site claims to specialise in.
Review provider breadth A library with several established providers can offer more variety in mechanics, design and game formats than a catalogue dominated by one source.
Test search and filters Search should handle exact titles and common terms, while filters should help narrow by category or provider without forcing endless scrolling.
Compare desktop and mobile availability Some titles may be missing on smaller screens or specific devices. Check the catalogue on the device you actually use.
Read game information Rules, RTP information where supplied, volatility descriptions and feature explanations should be accessible before or during play.
Look beyond newly added games A good library balances new releases with stable categories and clear navigation instead of pushing only the latest titles.
Check what happens when a game disappears If a title is removed, the site should not leave broken favourites or dead search results that create a confusing experience.

Conclusion
Game-library quality is about coverage, providers, search, mobile access and clear information. Raw title count is only one small part of the comparison.
