The single most useful number in any casino is the house edge — the long-run percentage the game keeps from every pound staked. Here's how the main games compare, and what it means for you.
| Game | Typical house edge | Type | Notes |
|---|---|---|---|
| Blackjack | ~0.5% | Skill + chance | With correct basic strategy; more decks nudge it up slightly. |
| Video poker | 0.5–5% | Skill + chance | Best paytables and optimal play get close to break-even. |
| Baccarat | ~1.06% | Chance | Betting "banker"; the "tie" bet is far worse value. |
| Craps (pass / don't pass) | 1.36–1.41% | Chance | Core line bets only; proposition bets are much worse. |
| Roulette — European | 2.70% | Chance | Single zero. Always choose this over American. |
| Slots | 2–15% | Chance | Varies hugely; check the game's published RTP. |
| Roulette — American | 5.26% | Chance | The double zero nearly doubles the edge. |
| Big Six wheel | up to ~24% | Chance | Among the worst value on the floor — best avoided. |
Figures are typical values and vary by operator, ruleset and region. A lower edge improves your chances but never guarantees a win — the maths always favours the house over time.
Blackjack played with correct basic strategy is the standout, at roughly 0.5%. Baccarat's banker bet (~1.06%) and the pass line in craps (~1.41%) follow closely.
The catch: the lowest-edge games tend to reward attention and discipline. The easy, fast games — most slots, American roulette — carry the highest edges.
Both. Individual hands are down to the cards, but your decisions change the long-run maths. Random play sits around a 2% edge; sound basic strategy cuts it to about 0.5%.
Even so, you're not expected to win over time. Strategy makes the game last longer and cost less — it doesn't flip the odds in your favour.
They're marketing — designed to attract new players and keep existing ones returning. "No deposit" spins let you try a game risk-free, which is why they're rare and capped.
Almost all bonuses carry wagering requirements: you must stake the winnings several times over before you can withdraw. Always read those terms first.
Volatility describes how often, and how big, a game pays. Low-volatility games pay small amounts frequently; high-volatility games pay rarely but larger.
It doesn't change the house edge — it changes the ride. High volatility means bigger swings in both directions, and a bankroll can vanish quickly.
Step two is staying in control. Set limits, treat it as entertainment, and know where to find support.
