Slots, table games and live casino — what they actually are

Slots are the most common casino game type by volume. A typical online casino offers several hundred slot titles from multiple studios, each with its own theme, feature set, and volatility profile. Volatility (or variance) describes how a slot pays: a high-volatility slot pays out less frequently but in larger amounts when it does; a low-volatility slot pays smaller amounts more often.

The RTP (return to player) figure represents the theoretical percentage of total stakes returned to players over millions of spins. An RTP of 96% means, in theory, £96 returned per £100 staked over a very long period — not per session, and not a guarantee.

Operators source slots from game studios, not directly from game companies like Aristocrat or IGT. The studios most commonly found in UK-licensed online casinos include Pragmatic Play, NetEnt, Microgaming, Big Time Gaming, Push Gaming, Relax Gaming and Hacksaw Gaming, among many others.

Standard table games — blackjack, roulette, baccarat, and poker variants — are available at most operators. These are software-based (not live dealer) and run by a random number generator. The rules of blackjack, for example, are consistent across operators, though specific rule variations (number of decks, surrender rules) can differ by title.

Roulette in UK-licensed casinos is typically European (single zero, 2.7% house edge) rather than American (double zero, 5.26% edge). Many operators offer both; if game mathematics matter to you, this distinction is worth checking before you play.

Live casino games are streamed in real time from a studio — or occasionally a real venue — where a human dealer runs the game. The most common live games are roulette, blackjack and baccarat. The experience is closer to a physical casino than a standard software game: you can see the physical wheel spin, the cards dealt, and the dealer's movements.

Most UK-licensed operators use Evolution Gaming (now just “Evolution”) as their primary live casino supplier. Evolution is the market-leading provider and its tables are reliable and consistent across the operators that carry them. Some operators, including 888 Casino, also run their own supplementary live studios — a distinction that adds variety to the live section.

Live casino tables typically have minimum stake requirements above those for standard software games. A live blackjack table might start at £1–5 per hand, which is worth noting if you prefer lower stakes.

Evolution and a few other studios have introduced hybrid game formats — Crazy Time, Dream Catcher, Monopoly Live — that sit between a slot and a live casino game. These use a physical wheel with a live presenter and incorporate multiplier segments that can deliver large single-session wins.

These formats are popular but have volatility profiles that can be extreme in both directions. They are worth understanding before playing: the core game is simpler than blackjack or roulette (you bet on a segment of the wheel), but the variance can be significant.
