Can You Bet on Both Red and Black in Roulette? Betting Explained
Roulette is one of the most recognisable games in any casino, with its spinning wheel and those striking red and black pockets.
Many players wonder what happens if you put chips on both colours at once. Is it a smart way to protect your stake, or does it just look that way at first glance?
This guide explains exactly how the bet works, what it pays, and why the green zero matters far more than most people think.
How Do Red And Black Bets Work On The Roulette Table?
Red and black are among the simplest wagers you can make. Place a chip on red or black and you are backing the next winning number to be one of the 18 red or 18 black pockets on the wheel. These are even‑money bets, which means a winning £5 stake is paid £5 in winnings, plus your £5 stake is returned.
Although the payout is 1:1, the probability of success is not exactly 50/50. A standard European wheel has 37 pockets in total (numbers 1–36 plus a single green zero), so a red or black bet wins on 18 of those 37 outcomes. That equates to a win probability of about 48.65% and a house edge of 2.70%.
American wheels add a green double zero as well, taking the total to 38 pockets. With the same 18 red and 18 black numbers, the chance of winning a red or black bet becomes roughly 47.37%, which increases the house edge to about 5.26%. These figures are averages over time and do not predict any single spin.
If the ball lands in a green pocket, red and black both lose, unless a specific table rule applies. Under la partage, common on some European tables, half of your even‑money stake is returned when zero hits. Under en prison, your even‑money stake is held “in prison” for the next spin; if it then wins, your original stake is released without additional profit. Always check the table rules before you play, as availability of these rules varies.
Red and black are treated as independent outcomes on each spin. Past results do not influence future results, and no pattern can guarantee a win. Table limits apply to both stakes and payouts, and all wins and losses are determined by the final resting pocket of the ball.
Roulette is a game of chance. Only stake what you can afford to lose, consider setting deposit and time limits, and take breaks to keep play enjoyable and within your means.
What Happens If You Bet On Both Colours At Once?
Backing red and black together means every coloured number on the wheel is covered. Because even‑money bets pay 1:1, one of your bets will win and the other will lose whenever the ball lands on a coloured number. If you place equal stakes on each colour, your net position on those spins is break‑even, although you are staking twice the amount to achieve that outcome.
Be aware that house rules vary: some tables may restrict opposite even‑money bets, so always check the game rules before you play. Outcomes are random and no staking pattern can change the underlying odds.
The exception is the green zero (and green double zero on American wheels). When a green number appears, both red and black lose at the same time. That is where the house edge sits. On a single‑zero (European) wheel there are 18 red, 18 black and 1 green pocket, so there is a 1 in 37 chance that both bets lose together. On a double‑zero (American) wheel there are 2 green pockets, so this happens 2 times in 38 on average.
In expected value terms, staking the same amount on both colours yields a long‑run loss equal to the game’s house edge on your total stake: about 2.70% per spin on single‑zero and about 5.26% per spin on double‑zero. For example, if you bet £1 on red and £1 on black each spin, your expected loss is roughly £0.054 per spin on a single‑zero wheel (around £5.40 over 100 spins), or about £0.105 per spin on a double‑zero wheel (around £10.50 over 100 spins).
This raises a natural follow‑up: if most spins return your stake, what do the numbers look like over time? In practice you will often break even on coloured results, punctuated by occasional greens that produce a full two‑stake loss. Variance may mean you see more or fewer greens than average in the short term, but over time the figures tend to align with the house edge, resulting in a gradual net loss overall.
Gambling should be entertainment, not a way to make money. Set limits, only stake what you can afford to lose, and take breaks. No strategy, including backing both colours, can eliminate the house edge or guarantee profit. 18+ only.
Payouts And Expected Returns When Betting Both Colours
If you place £5 on red and £5 on black, your total at risk on that spin is £10. On a European wheel, 36 of the 37 pockets are coloured either red or black, while the single green zero is neither colour.
For those 36 coloured outcomes, one £5 bet wins and the other £5 bet loses, so your net result for the spin is £0. On the remaining outcome, the green zero, both £5 bets lose and you are down £10 for that spin.
Put into expected terms:
- European wheel: you break even 36 times out of 37, and lose £10 one time out of 37. That equates to an average loss of about 27 pence per spin for a £10 total stake, which is roughly a 2.7% house edge on the total amount staked.
- American wheel: you break even 36 times out of 38, and lose £10 two times out of 38. That equates to an average loss of about 53 pence per spin for a £10 total stake, which is roughly a 5.26% house edge on the total amount staked.
Although this approach can feel steady because many spins end with no change, the cost over time comes from the green pocket(s). Betting both colours reduces volatility but does not alter the built‑in house edge.
Different table rules can affect what happens on zero (for example, some variants may offer partial returns on even‑money bets). Always check the specific rules for the game you are playing, as returns can vary by wheel type and house policy.
Roulette is a game of chance and outcomes are random. No staking pattern that only uses red and black can remove the house advantage, and past results do not predict future results. Only gamble what you can afford to lose and consider setting limits. 18+ only.
Can You Cover Zero Or Double Zero When Betting Both Colours?
Red and black do not include green. If you want a chance to return something when the ball lands in a green pocket, you must place a separate straight‑up bet on zero, or on both zero and double zero on an American wheel.
Placing this extra chip changes how your round settles without changing the underlying odds. Outcomes are random and each spin is independent, and no staking pattern can remove the built‑in house edge.
For example, with £5 on red, £5 on black, and £1 on zero:
- If red or black lands, one colour bet wins and the other loses, but the £1 on zero also loses. Your total for the spin is minus £1.
- If zero lands, the straight‑up bet pays 35 to 1 and typically returns £36 including the £1 stake. After subtracting the £10 lost on the colour bets, your net is £26 for that spin.
On an American wheel with both zero and double zero, you would need to bet on each green pocket separately to have coverage on both. On some European or French variants, special rules such as la partage or en prison may affect even‑money bets when zero lands, which can reduce losses on the red/black stakes, but the green pockets still favour the house overall.
This kind of add‑on does not eliminate the house edge. It simply shifts when wins and losses occur, trading frequent small negatives for the occasional larger positive. Over time you should expect the total return to be below break‑even, and you should only gamble with money you can afford to lose.
Are There Table Rules That Prevent Betting Both Colours?
In most casinos, you may place chips on both colours at the same time. It is treated as a standard combination of outside bets and, under normal circumstances, will not cause issues with the dealer. Do note that this is not an advantage play: the bets largely cancel each other out, and zero (or double zero, depending on the wheel) can still result in a loss on both colour bets.
Rules can vary by venue, game variant, and limit level. Some higher limit areas or private games may restrict opposite even‑money bets to keep the game flowing or to manage table exposure. Electronic or automated roulette terminals can also have specific settings about simultaneous opposite wagers, and promotional chips may be excluded from such bets.
Table minimums and maximums apply to each bet, and some venues may count opposing wagers towards your overall limit. If you are unsure, a quick glance at the table plaque or a polite check with the dealer or host will clarify what is permitted at that table.
From a numbers perspective, staking the same amount on red and black typically returns nothing gained when either colour hits, but you still risk losing when zero appears. On some European variants, rules like La Partage may reduce the loss on even‑money bets if zero lands, but the house edge remains and cannot be eliminated.
Play for entertainment only, never as a way to make money. Set limits, never chase losses, and only gamble if you are 18+.
Practical Examples Of Betting Both Red And Black
Imagine placing £10 on red and £10 on black on an even‑money bet. If the ball lands on red, that bet pays 1:1, so you receive £20 back in total: £10 in winnings plus the return of your £10 red stake. The £10 placed on black loses. If the ball lands on black, the situation is simply reversed.
In either of those colour outcomes, your bankroll is unchanged for that spin because one winning stake offsets one losing stake. You have action on the wheel, but no profit is created and no loss is recovered by covering both colours.
If the ball lands on zero, neither colour wins. Both £10 stakes are lost and you are £20 down for that spin. This is where the house edge comes from on colour bets: the green pocket(s) turn a neutral pair of colour bets into a net loss when they appear.
Across a session, those occasional green results create the gradual drain described earlier. Outcomes are random and independent, and no staking pattern can predict or influence where the ball will land.
Swap the amounts and the arithmetic is the same. Whether you use £1 chips or £25 chips, colour outcomes simply return your total stake for that round, while green outcomes cost the lot staked on both colours.
Betting larger amounts does not change the expectation; it only increases the size of wins and losses when zero appears. Covering both colours does not reduce the house edge or guarantee a profit. Set sensible limits, only stake what you can afford to lose, and avoid chasing losses.
How To Place Simultaneous Red And Black Bets On European And American Wheels
On the layout, the red and black betting areas sit among the outside bets around the edge of the table. To cover both colours, place equal-value chips on each area so that one stake is on red and an identical stake is on black.
Online tables mirror the same layout and rules. Selecting both colours with matching amounts achieves the same effect, with even-money payouts (1:1) applying to the winning colour while the other colour loses. In most cases this results in a net break-even on that spin, excluding the effect of green pockets and any variant-specific rules.
European wheels have one green pocket (0), while American wheels have two (0 and 00). When the ball lands in a green pocket, both red and black lose, which is the long-term cost of this approach. As a guide, the house edge on even-money bets is typically about 2.70% on European wheels and about 5.26% on American wheels.
Some European variants may apply rules such as la partage or en prison on zero, which can reduce the loss on even-money bets. Always check the specific game rules and paytable at your table, as these features are not universal.
Table limits also matter. Minimums and maximums apply to each outside bet in its own right, not to the combined total. For example, a £5 minimum per outside bet means you would need to place £5 on red and £5 on black to cover both, and each side is subject to its own maximum.
Set sensible limits, keep an eye on the impact of green results, and remember that outcomes are determined by chance on the wheel or RNG. Treat betting on both colours as a way to observe how roulette pays and how the house edge operates, not as a route to profit. Only wager what you can afford to lose, take breaks, and stop if play is no longer enjoyable.
