Roulette is one of the most popular table games you’ll find in a casino, whether online or in person. With a wide range of betting options, it’s easy to feel unsure about what each choice really means.
If you’ve wondered whether you can back two columns at once, how that affects your chances and payouts, and what rules apply, this guide will answer those questions in plain language. Read on to get a clear picture of the mechanics and implications of betting on two columns.
How Do Column Bets Work in Roulette?
Column bets are classed as outside bets and cover 12 numbers each on the betting layout. The table shows three long columns of numbers; to place a column bet you put chips on the box at the end of your chosen column marked “2 to 1.” If the winning number sits in that column, the column bet pays at 2 to 1.
This bet lets you cover a broad selection of numbers in a single stake, trading a smaller payout for wider coverage compared with inside bets like a straight-up number. The zero (and double zero in American roulette) sits outside these columns, which is why it affects the house edge.
A note on outcomes: each spin is independent and its result cannot be predicted. Keep that in mind when choosing how to spread your bets.
To move on, let’s check whether casinos allow backing more than one column at once.
Is It Allowed to Bet on 2 Columns at the Same Time?
Yes — you may place bets on two columns in the same spin. Both online and land-based casinos accept multiple column wagers, so you can cover 24 numbers by staking on two of the three "2 to 1" boxes.
Placing two column bets has a few straightforward consequences:
- You increase the total amount you risk for that spin because you are making two separate wagers.
- You broaden your coverage on the wheel, since two columns together include 24 of the 37 or 38 numbers depending on the wheel.
- The fundamental payout rules remain unchanged: a winning column bet pays 2 to 1 for the stake placed on that column, while the losing column bet is lost.
Remember that even with two column bets you do not cover the whole wheel. The remaining numbers, including zero, are still uncovered and can result in no column wins. Also bear in mind that staking on two columns doubles the stake exposed to the house edge; it does not reduce the house edge itself.
What Are the Odds When Betting on 2 Columns?
Covering two columns means you back 24 numbers out of the total wheel numbers. In European roulette (single zero) that is 24 out of 37, roughly 64.9%. In American roulette (with 00) it is 24 out of 38, about 63.2%.
Those figures reflect the proportion of numbers you have covered, not a guarantee of success. If the ball lands on zero or on the single column you did not back, both column bets lose. Splitting the wheel this way affects both the chance of a win and the size of any net return when you do win.
To make the maths clearer, consider the payouts and the resulting expected outcome when you place equal stakes on two columns. A winning column pays 2 to 1, so if you stake 1 unit on each of two columns:
- If one of your columns comes up you receive 3 units from that winning bet, so with 2 units staked in total your net profit is 1 unit.
- If the ball lands on one of the numbers you did not cover (including zero or 00) you lose both stakes, a net loss of 2 units.
Putting the probability and payoff together shows the house edge remains the same as for single-column or other even-money bets. For example:
- European roulette: win probability 24/37 ≈ 64.9%, lose probability 13/37 ≈ 35.1%. Expected return per 2 units staked is about -0.0542 units, which is a loss rate equivalent to the standard house edge of 2.7% per unit.
- American roulette: win probability 24/38 ≈ 63.2%, lose probability 14/38 ≈ 36.8%. Expected return per 2 units staked is about -0.1052 units, which corresponds to the higher house edge of about 5.26% per unit.
Understanding these probabilities and how the payout is applied helps you weigh the likelihood of a small net win against the risk of a larger loss. Remember that over the long term the built-in house edge means losses are statistically more likely than gains.
Payouts for 2 Column Bets Explained
Each column bet pays at 2 to 1. When you win on a column, the payout applies only to the column that contains the winning number — a single number cannot belong to more than one column.
For example, if you stake £5 on two columns (total £10) and the winning number is in one of those columns, that winning column returns £10 in profit plus your £5 stake, so you receive £15 from the winning bet and your losing £5 wager is lost. The net return on the spin in that case is £5 profit on a £10 total stake.
Payouts remain the same regardless of how many columns you back; the trade-off is between coverage and net return. With that in mind, the effect of the zero becomes clearer.
What Happens If the Ball Lands on Zero?
If the ball lands on zero, column bets do not win because zero is not part of any column. Both column wagers will lose under standard European or American roulette rules. The presence of the zero pocket removes what would otherwise be a straightforward 1 in 37 or 38 chance for each number in those wheels.
This is one of the features that creates the house edge and is why the number of zero pockets on the wheel changes the overall expected return for players. In practice this matters because:
- zero is excluded from all column and most even-money bets, reducing the chance those bets succeed;
- payouts for winning column bets stay the same even though there is an extra losing outcome, which lowers the long-term return;
- American roulette with two zero pockets therefore gives the house a larger built-in advantage than European roulette with a single zero.
Knowing how zero affects your coverage is important when deciding how much to stake on multiple columns. If you cover large parts of the table you still face the same zero-related loss when the ball lands on that pocket, so staking and risk management should take that into account.
With rules and payouts covered, it helps to clear up some common misunderstandings.
Myths About Multiple Column Betting
Several persistent myths surround multiple column betting. One is that covering more columns guarantees a win each spin — covering 24 numbers does not eliminate the possibility of defeat, because zero and the remaining column still exist.
Another is that certain systems can turn column bets into a long-term winning strategy. No betting pattern can alter the expected return built into the wheel’s layout; past spins do not influence future outcomes. Treat these claims with caution and focus on the factual mechanics explained earlier.
If you’re comparing different bet types, it’s useful to see how column bets stack up.
Comparison: Column Bets vs Other Roulette Bets
Column bets cover 12 numbers and pay 2 to 1, sitting between inside bets and the even-money outside bets in both risk and reward. Outside even-money options (red/black, odd/even, high/low) cover nearly half the wheel and pay 1 to 1, offering higher win frequency but smaller payouts. Inside bets such as straight-up numbers cover a single number and pay up to 35 to 1, with far lower hit rates.
Across these bet types the expected house edge remains driven by the zero pockets: about 2.7% for single-zero wheels and roughly 5.26% for double-zero wheels. Your choice will depend on whether you prefer wider coverage with smaller jackpots or narrower coverage with larger ones.

Key Rules to Remember for Betting on 2 Columns
Before you place two column bets, keep these practical points in mind so your play is clear and controlled.
You may place bets on any two columns per spin, staking on the “2 to 1” boxes at the end of each chosen column. Each column covers 12 numbers (zero and double zero are excluded from columns). Only the column containing the winning number pays 2 to 1; stakes on the other column are lost. If zero appears, both column bets lose. The total of your column stakes is your combined risk for that spin, and the presence of zero(s) determines the house edge.
If you ever want to limit how much you play or need support, tools such as deposit limits and self-exclusion options are available. Play within your means and make choices that fit your budget.
That covers the practicalities of betting on two columns and brings together the odds, payouts and rules so you can make an informed decision next time you sit at the table.
