Online Slots — The Most Popular Casino Game
Slots account for approximately 70% of online casino revenue in the UK. They’re the simplest games to play — no strategy required — and offer the widest variety of themes, features, and payout structures.
Types of Online Slots
- Classic Slots — 3 reels, limited paylines (1–5), simple gameplay inspired by traditional fruit machines. Examples: Mega Joker, Break da Bank.
- Video Slots — 5+ reels, multiple paylines (10–100+), rich graphics, bonus features, and storylines. This is the dominant category. Examples: Starburst, Gonzo’s Quest, Book of Dead.
- Megaways Slots — dynamic reel systems offering up to 117,649 ways to win per spin. The number of symbols on each reel changes every spin. Examples: Bonanza Megaways, Big Time Gaming titles.
- Progressive Jackpot Slots — a portion of every bet contributes to a growing jackpot that can reach millions of pounds. Examples: Mega Moolah (record £13.2m payout), Mega Fortune, Divine Fortune.
- Branded Slots — licensed games based on films, TV shows, bands, or cultural properties. Examples: Jurassic World, Game of Thrones, Narcos.
Understanding Slot RTP
Return to Player (RTP) is the theoretical percentage of wagered money that a slot pays back to players over millions of spins. An RTP of 96% means that for every £100 wagered, the game returns £96 on average. The remaining 4% is the house edge.
| RTP Range | Rating | Example Slots |
|---|---|---|
| 97%+ | Excellent | Mega Joker (99%), Blood Suckers (98%), Starmania (97.87%) |
| 96–97% | Good | Starburst (96.09%), Gonzo’s Quest (96%), Book of Dead (96.21%) |
| 95–96% | Average | Many branded slots fall in this range |
| Below 95% | Below Average | Check individual game info — some popular titles have lower RTPs |
Slot Volatility Explained
Volatility (or variance) describes the risk profile of a slot:
- Low volatility — frequent small wins, lower risk, good for casual play and bonus wagering
- Medium volatility — balanced mix of win sizes and frequency
- High volatility — infrequent but larger wins, higher risk, longer dry spells between payouts
Your choice should match your bankroll and playing style. High-volatility slots require a larger bankroll to weather the variance, while low-volatility slots offer steadier, more predictable sessions.
Table Games — Strategy Meets Entertainment
Blackjack
Blackjack is the most popular table game at UK online casinos, offering one of the lowest house edges in the casino when played with basic strategy — as low as 0.5% in some variants.
Common online blackjack variants include Classic Blackjack, European Blackjack, Blackjack Surrender, Multi-Hand Blackjack, and Perfect Pairs. Each has slightly different rules regarding doubling down, splitting, and side bets. Always check the specific rules of the variant you’re playing.
Roulette
Online roulette comes in three primary variants:
| Variant | Zeros | House Edge | Best For |
|---|---|---|---|
| European Roulette | Single zero (0) | 2.70% | Best odds for players |
| French Roulette | Single zero (0) + La Partage | 1.35% (even bets) | Lowest house edge available |
| American Roulette | Double zero (0, 00) | 5.26% | Avoid — significantly worse odds |
Baccarat
Baccarat is a straightforward game with three possible outcomes: Player win, Banker win, or Tie. The Banker bet carries a house edge of approximately 1.06%, making it one of the best bets in the casino. The Tie bet (house edge ~14%) should generally be avoided despite its attractive 8:1 or 9:1 payout.
Craps
Craps is one of the most exciting casino games, whether played online or at a live table. The game centres around dice rolls, with the Pass Line bet (house edge 1.41%) being the most fundamental wager. Combined with Odds bets (which carry zero house edge), craps offers some of the best mathematical odds in the entire casino.
Online craps is available in both RNG (random number generator) and live dealer formats. For UK players, we’ve written dedicated guides covering how to play craps, craps strategy, and craps odds and payouts. You can also find the best online craps sites for UK players.
Live Dealer Games — The Premium Casino Experience
Live dealer games bridge the gap between online convenience and the authentic atmosphere of a land-based casino. Real dealers operate physical tables from professional studios, streamed in HD video to your device in real time.

Game Shows — The Newest Category
Evolution Gaming pioneered the game show category, creating TV-style productions with interactive elements. These games have become hugely popular with UK players:
- Crazy Time — money wheel with four bonus games, offering multipliers up to 25,000x
- Dream Catcher — simple money wheel format with multiplier segments
- Lightning Roulette — European roulette with random lightning multipliers up to 500x

- Deal or No Deal Live — interactive version of the popular TV show
Game shows typically have higher house edges than traditional table games but offer entertainment value and the potential for large multiplier wins.
Video Poker
Video poker combines elements of slots and poker, requiring some degree of strategy to optimise returns. The best video poker variants offer RTPs above 99% when played with perfect strategy — making them some of the best-value games in the casino.
| Video Poker Variant | Optimal RTP | Strategy Complexity |
|---|---|---|
| Jacks or Better (9/6) | 99.54% | Moderate |
| Deuces Wild (Full Pay) | 100.76% | High |
| Double Bonus Poker | 99.17% | Moderate |
| Joker Poker | 98.60% | Moderate |
Scratch Cards and Instant Wins
Online scratch cards and instant win games offer quick-play entertainment with immediate results. They’re typically simple — reveal symbols or numbers to see if you’ve won. RTPs range from 60% to 95%, with most falling in the 85–92% range. While convenient, they generally offer worse value than slots or table games.
RTP Comparison Across Game Categories
| Game Category | Typical RTP Range | House Edge | Strategy Required |
|---|---|---|---|
| Video Poker (optimal play) | 99.0–100.7% | 0–1% | Yes — significant |
| Blackjack (basic strategy) | 99.0–99.5% | 0.5–1% | Yes — moderate |
| Craps (Pass + Odds) | 98.6–99.4% | 0.6–1.4% | Minimal |

Frequently Asked Questions
What casino game has the best odds for players?
Blackjack with basic strategy offers the lowest house edge among common casino games at around 0.5%. Craps with Pass Line plus maximum Odds bets comes close at 0.6%. Video poker variants like Jacks or Better (9/6 pay table) can return 99.54% with optimal play. French roulette with the La Partage rule has a house edge of just 1.35% on even-money bets.
What does RTP mean in online casino games?
Return to Player (RTP) is the theoretical percentage of all wagered money that a game returns to players over its lifetime. An RTP of 96% means the game pays back £96 for every £100 wagered on average. This is a long-term statistical measure — individual sessions will vary significantly above and below the RTP figure due to variance.
Are online casino games rigged?
Games at UKGC-licensed casinos are not rigged. They use Random Number Generators (RNGs) that are independently tested and certified by agencies like eCOGRA, iTech Labs, and GLI. The UKGC requires all licensed operators to use certified fair games and publishes audit results. The house edge is built into the mathematics of each game — the casino doesn’t need to cheat to be profitable.
Can I play live dealer craps at UK online casinos?
Yes, several UK casinos offer live and first-person craps from providers like Evolution Gaming. First Person Craps provides an immersive 3D experience with the option to switch to a live-hosted table. You can find our recommended operators on our best online craps sites page, and learn the game with our how to play craps guide.
What is the difference between high and low volatility slots?
Low volatility slots pay out frequently but in smaller amounts, making them suitable for casual play and bonus wagering. High volatility slots pay out less often but with larger individual wins, requiring a bigger bankroll to sustain longer sessions. Medium volatility offers a balance between the two. Your choice should depend on your budget, playing time, and risk tolerance.
