- Online casino games fall into three groups: slots, RNG table games and live dealer games.
- Blackjack played with basic strategy and single-zero roulette offer some of the lowest house edges.
- Every game at a UKGC-licensed casino is independently tested for fairness.
If you enjoy table games, learn basic blackjack strategy. It is the one casino skill that genuinely lowers the house edge.
Types of online casino games
Online slots
The most popular casino games in the UK by far. Video slots range from simple low volatility games to high volatility Megaways and progressive jackpots. Explore video slots.
Table games
Digital versions of casino classics such as roulette, blackjack, baccarat and poker variants, run by a random number generator (RNG). They are fast, available at low stakes and great for learning the rules.
Live dealer games
Real tables, real dealers and real cards or wheels, streamed to your device in HD. Read our live casino guide.
Instant win, crash and specialty games
Scratchcards, Slingo, crash games and other quick-fire formats found in most casino lobbies.
House edge and RTP by casino game
Every casino game has a built-in house edge – the average share of stakes the casino keeps over time. The lower the house edge, the better the odds for players.
| Casino game | House edge / RTP | Notes |
|---|---|---|
| Blackjack | Around 0.5% with basic strategy | Depends on table rules |
| French roulette (La Partage) | 1.35% on even-money bets | Half back on zero |
| European roulette | 2.70% | Single zero |
| Baccarat (banker bet) | About 1.06% | Commission charged on banker wins |
| American roulette | 5.26% | Extra double zero |
| Video slots | RTP usually 94%–97% | Varies by game and version |
| Jackpot slots | RTP often lower | Part of stakes funds the jackpot |
Luck vs skill in casino games
Slots and roulette are pure games of chance – no strategy changes the house edge. Blackjack is different: playing basic strategy reduces the house edge considerably, although the casino still keeps an advantage over time.
Which casino games have the best odds?
- Blackjack with basic strategy and good table rules.
- Baccarat, betting on the banker.
- French or European roulette, thanks to the single zero.
- High RTP slots – look for 96% or above.
Using casino bonuses on table and live games
Bonus terms often weight games differently. Slots usually contribute 100% towards wagering, while table and live games may contribute less or be excluded entirely. Free spins can only be used on the slots named in the offer.
Are online casino games fair?
Yes, at licensed casinos. The UK Gambling Commission requires games to be tested by independent labs, and RNG results must be genuinely random. Live casino results come from physical equipment filmed in real time.
Casino games on mobile
