The casino roulette payout chart No one bothered to explain until they stopped paying out

Look, the moment you stare at a roulette table you’re not seeing colours; you’re seeing a spreadsheet disguised as a wheel. A single‑zero French wheel with 37 pockets yields a house edge of 2.7 %, whereas the double‑zero American version inflates it to 5.3 %. That 2.6 % difference translates directly into the payout chart you’ll be wrestling with when you try to ‘beat’ the odds.

Take the classic “inside bet” on numbers 5, 17 and 32. The nominal payout reads 35 : 1, but the true return‑to‑player (RTP) on a single‑zero wheel is (35 / 37) ≈ 94.6 %. Compare that to a “split” covering 7‑8, which pays 17 : 1, yet its RTP is (17 / 38) ≈ 44.7 % – a stark illustration that the chart isn’t just tidy numbers, it’s a tax schedule.

And then there’s the “dozen” bet. You wager £10, you win £30 if a ball lands in 13‑24. The raw maths: 12 winning numbers out of 37, so the probability is 12 / 37 ≈ 32.4 %. Multiply by the 3‑to‑1 payout and you get an expected value of £10 × (0.324 × 3) ≈ £9.72 – a loss of 28 pence per £10 stake every spin.

Why the payout chart matters more than any “VIP” promise

Bet365 will flash a “VIP treatment” banner promising exclusive tables, yet the underlying chart remains unchanged. The “even‑money” bets (red/black, odd/even) pay 1 : 1 but suffer a 2.7 % house edge, meaning a £50 bet yields an expected profit of £-1.35. William Hill’s glossy “gift” spin on the roulette lobby is just a marketing veneer; the numbers stay the same.

Because the payout chart is static, any “free” spin only shifts variance. If you spin a wheel with a 0.5 % chance of landing on zero, the expected loss on a £20 bet is £0.10 – hardly a charitable donation.

But the chart also reveals hidden quirks. The “en prison” rule on single‑zero tables halves the loss on zero, effectively boosting RTP by about 0.6 %. In plain terms, a £100 even‑money bet after a zero lands in prison returns £100 instead of losing it, shaving the house edge down to roughly 2.1 %.

Practical ways to read the chart without drowning in jargon

First, convert every payout into an “expected return” percentage. For a straight‑up bet on 23, the formula is (35 / 37) × 100 ≈ 94.6 %. Write it down beside the 2.7 % house edge and you instantly see the gap.

Second, rank bets by variance. A single number bet has a standard deviation of roughly 1.79, whereas a column bet’s deviation hovers near 0.65. If you prefer smoother bankroll swings, stick to column bets despite the lower payout.

Third, factor in table limits. A live table at 888casino caps the maximum single bet at £500. If you aim to exploit a 5 % edge by gambling on a “zero spin” promotion, the ceiling slams you back to a meagre £25 expected profit – not exactly a windfall.

• Calculate expected loss: Stake × House Edge.
• Adjust for “en prison”: Divide loss on zero by 2.
• Compare variance: High payout = High variance.

Now, let’s juxtapose roulette with slots. A spin of Starburst can flash a win in 0.5 seconds, but its RTP of 96.1 % mirrors a red/black bet on a single‑zero wheel. Gonzo’s Quest, with a higher volatility, mimics the rollercoaster of chasing a straight‑up number – big payouts, rare hits, identical to the 2.7 % edge you’re already paying.

Because the payout chart is immutable, any “free” bonus is just a re‑skinned version of the same equation. A £10 “free” spin on a roulette app still faces the same 2.7 % edge, which translates to a statistical loss of 27 pence – a paltry gesture that hardly justifies the hype.

And if you think the chart changes with the time of day, you’re dreaming. The wheel’s physics and the casino’s math stay constant whether the sun sets over London or the servers reboot in Malta.

Finally, beware the hidden fees. Some operators levy a £2.50 “service charge” on every roulette session longer than 30 minutes. That fee, when amortised over 100 spins, adds roughly 0.25 % to the house edge – an invisible tax that never appears on the payout chart.

Honestly, the only thing more irritating than a 0.5 % variance in an “en prison” rule is the absurdly tiny font size used for the terms and conditions on the roulette lobby page – you need a magnifying glass just to see the rule about zero handling.
