Split bet meaning in roulette

Split bet meaning: one chip, two numbers

On the roulette layout, numbers sit in a grid of three columns and twelve rows. Any two numbers that share a border can be backed together by placing one chip across that border. That is a split bet. If either number comes up, the chip wins 17 times its value. On French tables it is called à cheval, meaning astride, which describes how the chip sits.

Splits are one of the inside bets, the group of bets placed on the numbered part of the layout. They sit between a straight-up bet on one number and a corner bet on four, in both payout and frequency.

Roulette split bet vs splitting in blackjack

The words overlap, which causes plenty of confusion in search results. In blackjack, to split means turning a pair, such as two 8s, into two separate hands by adding a second stake equal to the first. It is a playing decision, not a bet type. In roulette, a split is a bet on two numbers and involves no decision once the wheel spins. This entry covers the roulette meaning; our blackjack rules guide covers the other.

Split bet payout, odds and house edge

Every bet on a single-zero wheel is priced so the house keeps 1 in 37 of stakes on average. A split wins twice as often as a straight-up bet and pays roughly half as much, so its cost is identical. Standard figures appear in the Wizard of Odds roulette guide (opens in a new tab) and our roulette odds and payouts page.

How many split bets are on a roulette table?

A European layout offers 60 splits in total. Within each of the twelve rows there are two side-by-side pairs, giving 24. Down each of the three columns there are eleven stacked pairs, giving 33. Add the three splits with zero, which are 0/1, 0/2 and 0/3, and you reach 60. American layouts add a split between 0 and 00, plus their own zero pairings.

Splits must be neighbours on the betting layout, not on the wheel. Numbers 32 and 15 sit next to each other on the wheel but cannot be split on the table. Bets on wheel neighbours are made through racetrack call bets instead.

How to place a split bet online

1. Check the table limits; the maximum on a split is usually lower than on outside bets.
2. Pick a chip value.
3. Tap exactly on the line separating the two numbers; the chip should straddle both boxes.
4. Confirm the highlighted numbers are the pair you meant, then lock in the bet.
5. Wait for the spin; at least 5 seconds pass between RNG rounds under UK rules.

Split bets in pounds: worked examples

• £2 on 8/11: if 8 or 11 lands, you win £34 and keep your £2 stake, so £36 returns. Otherwise you lose £2.
• £1 on 0/2 and £1 straight up on 0: £2 staked. Zero lands: £17 + £35 profit, £54 back in total. Two lands: £17 profit, £18 back from £2, net +£16. Anything else: −£2.
• £1 on six different splits: £6 per spin covering 12 numbers. A hit returns £18, net +£12, about one spin in three on average; a miss costs £6.

Splitting stakes across more pairs changes how often you see a return but not the 2.70% cost. Our casino bankroll basics show how to plan total spend around that.

Split bets inside call bets: tiers and orphelins

Racetrack call bets on French and European tables are mostly bundles of splits on numbers that sit together on the wheel. Tiers du cylindre uses six chips on six splits covering the 12 numbers opposite zero: 5/8, 10/11, 13/16, 23/24, 27/30 and 33/36. Orphelins uses five chips: one straight up on 1 and four splits, 6/9, 14/17, 17/20 and 31/34. Each chip is still a normal split with a normal 17:1 payout, so the edge does not change. The racetrack is explained in how to play live roulette.

UK rules that apply to split bets

Roulette is outside the online slot stake limits, so split maximums come from the table, not from law. RNG roulette must take at least 5 seconds per game cycle and cannot autoplay since 17 January 2025, as set out in the Commission’s speed of play decision (opens in a new tab). Placing many splits at once can make stakes per spin climb quickly; reality checks and a time-out are worth using if sessions run long.
