Game categories
What's actually in a UK casino library
The headline 'number of games' tells you less than how that number breaks down. Here's how the main categories play, especially on a phone, and where our five operators pull apart.
Slots
Slots are the bulk of every library here, and the number ranges widely — NetBet pushes past a thousand titles while Admiral keeps a tighter, Novomatic-led shelf. On a phone the things that matter are load time and whether the game is built for portrait play; newer studios like Pragmatic Play and Hacksaw handle that better than some older NetEnt classics. If volume is your priority, NetBet and Casumo have the deepest shelves of the five.
Live casino
Live casino streams a real dealer to your screen in real time, and four of our five run it through Evolution, the studio the big brands use. Casumo and Midnite present it cleanly on mobile, with tables that fit a phone without endless pinching. It's the most data-hungry part of any casino, so a steady connection counts for more here than raw library size.
Table games
Beyond the live tables, most sites also offer software versions of blackjack, roulette and baccarat that you play against a computer rather than a dealer. They load instantly and work offline-style without a video stream, which makes them the practical choice on a patchy mobile signal. The selection is fairly even across these operators — this is rarely the category that separates them.
Game shows and instant games
The newer corner of the catalogue covers game-show formats like Crazy Time and quick instant-win titles. Casumo and Midnite lean into these, and they're built squarely for short mobile sessions rather than long sittings. 10Bet and Admiral carry fewer of them, in keeping with their more traditional, sports-led or arcade-led roots.
Library depth and live-casino setup are two of the eight points we score in the full comparison. For the studios behind these categories, see our game providers guide.
