The four families, and what each one costs to play
The number that matters is the house edge: the share of everything staked that the operator keeps over a long run. On slots it is usually quoted the other way round, as return to player, which sounds friendlier and means the same thing.
| Family | Typical house edge | Rounds per hour | What actually drives the result |
|---|---|---|---|
| Slots | 4-8% | 400-800 | Nothing you do; only the game you chose |
| Blackjack | 0.5-2% | 60-100 | Rules at the table and whether you follow strategy |
| Roulette | 1.35-5.26% | 40-60 | How many zeros the wheel has |
| Live casino | 1-5%, higher on game shows | 30-50 | The variant, plus the pace the dealer sets |
Read the third column next to the first. A 4% edge at 600 spins an hour empties a wallet faster than a 5% edge at forty rounds, and that single fact explains most of the difference between an evening that lasts and one that does not.
Slots: the only decision is which game
There is no skill element in a slot and no decision after the stake. Everything that will happen was set by the studio when they built the maths model and by the certified RTP version the operator chose to run. That makes slots the easiest family to shop in: pick a higher RTP, match the volatility to how long you want the session to last, and then stop thinking about it. The full explanation, including what a 96.5% return does and does not promise, is on the online slots page.

That lobby is doing something worth noticing. The jackpot counter at the top is the largest number on the screen, the grid underneath is sorted by what other people play, and the RTP of every one of those tiles is a click away inside the game rather than on the tile. None of that is against the rules. It just means the information you need is never where your eye lands first.
Table games: the house edge is negotiable
At a table, the rules change the price. Blackjack paying 6:5 instead of 3:2 costs you roughly 1.4 percentage points, which is more than the entire edge of a well-chosen table. A roulette wheel with one zero is about half the price of one with two. These are not small differences dressed up as big ones — they are the difference between a game that gently costs you money and one that does it briskly.
People spend an hour choosing a slot and thirty seconds choosing a blackjack table. It should be the other way round: on the slot you cannot change the price, and at the table you can.

Live casino: a television studio with a bet attached
Live tables are ordinary table games streamed from a studio with a human dealer, which changes nothing about the maths and everything about the pace and the feel. The commercial shift in recent years has been towards game shows — money wheels, bonus rounds, presenters — where the house edge is typically several times that of a live blackjack table and the entertainment is doing the selling. What the studios look like and how the limits are built is set out at live casino.
What to check before you play anything
- The info screen. RTP, volatility, max win and whether a jackpot needs a qualifying stake.
- The table rules. On blackjack: the payout for a natural, whether the dealer hits soft 17, how many decks.
- Game contribution. If you are playing with a bonus, table games usually count for 10% of wagering or nothing at all.
- The clock. Rounds per hour is the multiplier on everything else.
Every site in our tables goes through the same four steps in the same order. We judge what actually happens, not what the front page says.How we test a casino
Which casino game has the best odds?
Blackjack with good rules and basic strategy, at roughly 0.5% house edge. Nothing else licensed in the UK comes close, and the cheat sheet is what gets you there.
Do table games count towards a bonus?
Usually at a heavily reduced rate — 10% is common and some sites exclude them entirely. Always read the contribution table, not the headline.
Is live casino fairer than software games?
Neither is unfair. A live table uses real cards and a real wheel; a software game uses a certified RNG. The edge comes from the rules, not from the medium.
Why are the game shows so popular if the edge is worse?
Because they are entertainment first. That is a legitimate reason to play one — it is only a problem when the price is mistaken for the price of a blackjack table.
