Ask any regular at a UK casino which game offers the better return and you will get a different answer depending on who you speak to. The truth sits in the published house edge figures, and they tell a more nuanced story than the pub argument suggests. Slots carry higher volatility and, on paper, a larger built-in advantage for the operator. Table games look gentler, but only if you play the right bets. Here is how the numbers actually stack up.

Understanding return-to-player percentages matters because they decide how much of every £100 staked comes back over the long run. That figure is fixed for slots and variable for tables, which is the first clue to why a straight comparison is tricky. Neither category wins outright across the board.
The house edge in plain numbers
Modern UK-licensed slot games typically publish RTPs between 92% and 97%. That means the house edge ranges from roughly 3% to 8% depending on the title, and some progressive jackpot games sit lower still because a slice of every stake funds the prize pool. A 96% RTP slot returns £96 for every £100 wagered over millions of spins , but only in theory, and never in a neat sequence.
Table games are a different beast because you choose your bet. European roulette carries a 2.7% house edge, while the American double-zero version jumps to 5.26%. Blackjack played with basic strategy can push the edge below 1% on favourable rulesets. Baccarat on the banker bet sits at about 1.06%, and the player bet around 1.24%.
Set those side by side and the pattern is clear. A well-played table game beats almost every slot on pure mathematics. A badly played one does not.
| Game | Typical house edge | Typical RTP |
|---|---|---|
| Slots (standard) | 3% – 8% | 92% – 97% |
| European roulette | 2.70% | 97.30% |
| Blackjack (basic strategy) | 0.50% – 1% | 99% – 99.50% |
| Baccarat (banker) | 1.06% | 98.94% |
| Craps (pass line) | 1.41% | 98.59% |
Why slots still feel like better value
RTP is not the same as experience. Slots offer something tables rarely match: the chance of a multiplier that turns a 50p spin into a four-figure return. That upside is baked into the maths, which is precisely why the base game pays less frequently. A 96% slot might return nothing for 200 spins and then deliver a 500x win in a single bonus round.
Stake flexibility is another factor. Many UK slots accept spins from 1p upwards, so a £10 session can last far longer than the same amount on a £5 minimum table. For players who want entertainment per pound rather than the best theoretical return, that matters enormously.
Speed also plays a role. A slot player might complete 600 spins an hour; a blackjack player perhaps 60 hands. Higher RTP on the table game does not automatically mean a smaller loss in real terms, because the slot player is cycling far more money through the machine. The house edge applies per wager, not per session.
Choosing the game that suits your bankroll
If your priority is stretching a bankroll with minimal exposure, blackjack using basic strategy is hard to beat. Learn the correct plays and a sub-1% edge gives you the fairest fight in the building. European roulette is simpler to learn and still respectable at 2.7%, though avoid the American wheel entirely.
Slots suit a different mindset. Accept the higher edge in exchange for variance, and pick titles with published RTPs at the upper end of the range. Anything at 96% or above is competitive; anything under 94% is worth a second look before you commit.
Ultimately, neither format pays better in every scenario. Table games reward skill and discipline; slots reward patience and luck. Check the RTP, understand the rules, set a spending limit in pounds before you start, and treat the difference between the two as a question of style rather than superiority.
