Casino Games Guide: Slots, Live Dealer, Blackjack and Roulette
An overview of the main game types at UK licensed casinos, with a focus on fair play, RNG and software providers.
How UK Licensed Games Are Regulated
All remote gambling offered to British players is regulated by the UK Gambling Commission. Casino games must use certified random number generators (RNG) where the outcome is determined by software, and live dealer games must be run in line with the same standards. Independent testing bodies assess RNG and game logic to ensure fairness. UK operators typically source games from established providers such as NetEnt, Evolution, Microgaming, Playtech, Pragmatic Play and Red Tiger, many of which publish RTP (return to player) figures for transparency.
Online Slots
Slots are the most numerous game type at UK online casinos. Each slot uses an RNG to determine the result of every spin. The RTP is the percentage of total stakes that the game is designed to return to players over the long term; for example, a 96% RTP means that for every £100 wagered, the game is designed to return £96. RTP does not guarantee results in a single session. Many UK slots from providers like NetEnt, Pragmatic Play and Microgaming have RTPs in the mid-to-high 96% range. Volatility (variance) describes how often and how large wins tend to be—high volatility slots pay less frequently but can deliver larger wins. Game counts at top UK sites often run into the thousands, with themes and features varying widely.
Live Dealer Games
Live dealer games stream real tables and dealers from studios. You place bets via the same interface as RNG table games, but the outcome is determined by physical equipment (e.g. cards, wheels) rather than software alone. Evolution and Playtech are leading suppliers of live blackjack, roulette, baccarat and game shows. UK licensed operators must ensure that live games are fair and that the stream and betting systems are secure. Live games appeal to players who want a more social, land-based feel while playing online.
Blackjack
Blackjack is available in both RNG and live dealer formats at UK casinos. The aim is to get a hand total closer to 21 than the dealer without going over. RNG blackjack uses a certified random number generator to shuffle and deal; RTP depends on rules (e.g. number of decks, dealer stand/hit on soft 17). Live blackjack follows the same rules but with a human dealer. Strategy can reduce the house edge in blackjack, but the house always has a mathematical advantage over the long term. Check the rules and RTP for each variant on the operator’s site.
Roulette
Roulette involves betting on where a ball will land on a spinning wheel. European roulette has one zero and a lower house edge than American roulette (two zeros). UK sites offer both RNG and live roulette from providers such as Evolution and Microgaming. RTP for European roulette is typically around 97.3%. As with all casino games, outcomes are random and past results do not influence future spins. Choose a game whose rules and limits suit you and gamble only what you can afford to lose.
Choosing Games at a UK Casino
When comparing UK licensed casinos, look at the breadth of slots and table games, the mix of software providers, and whether RTP is disclosed. A large library from reputable providers gives you more choice and generally indicates a commitment to quality and fairness. For more on how we review operators, see our About Us and Operator Reviews.
