Casino Terms Glossary
Column — is a common roulette wager that covers one vertical line of 12 numbers on the table layout and pays 2:1 when any of those numbers hit. In casino gambling, the term can also describe a vertical reel position in slots, but most players use it for the roulette column bet that balances coverage with moderate risk and steady returns.
Understanding Column
In gambling, Column meaning refers primarily to the roulette column bet. The Column definition is a wager placed on one of three vertical groups of 12 numbers on the layout; it pays 2:1 when any covered number hits and loses on 0 (and 00 in American roulette). Understanding what is a Column bet matters because it balances coverage and payout, affects bankroll volatility, and pairs well with other table bets. It keeps house edge similar to dozens. At 101RTP, we show how column bets influence variance and bankroll through expert guides, honest casino and slot reviews, and practical tool demos.
Examples of Column
Common ways players use Column in casino play include:
- Roulette: Place a chip on “2nd Column” to cover 12 numbers; a hit on 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, or 35 pays 2:1; 0/00 lose.
- Combo play: Pair a Column with Red/Black to smooth variance; expect overlaps that change net returns when both win.
- Wheel choice: On European (single‑zero) wheels, house edge is 2.70%; on American (double‑zero), it’s 5.26% for Column bets.
- Slots usage: In some slots, “column” simply means a vertical reel; features may expand a column or turn an entire column wild.
FAQs
What is a Column bet in roulette?
A Column bet is a casino term for wagering on one of three vertical groups of 12 numbers on the roulette layout. It pays 2:1 when any covered number hits, and it loses on 0 (and 00 on American wheels). It offers moderate risk with higher hit frequency than straight-up numbers.
How does a Column bet compare to dozens?
Both Column and dozen bets cover 12 numbers and pay 2:1, with the same house edge (2.70% on European, 5.26% on American). The difference is layout: dozens are horizontal groups (1–12, 13–24, 25–36), while columns are vertical groups. Players often choose based on preferred number patterns or table visibility.
Can a Column bet help clear casino bonuses?
Often roulette contributes little or is excluded from wagering, so Column bets may not count. Slots usually contribute more. Use 101RTP’s Bonus Value Score calculator to compare slots and stake sizes for better expected value when clearing bonuses, and always read a casino’s terms before planning any gambling strategy.
Is the Column meaning the same in slots and roulette?
Column meaning differs by game. In roulette, it’s a 12-number 2:1 wager. In slots, column typically refers to a vertical reel position that can expand, nudge, or turn wild in features. The Column definition in general casino talk most often points to the roulette bet unless context says otherwise.
Do players gain an edge using Column systems?
No. Systems like progressions do not change the house edge on Column bets. While a Column offers a 2:1 payout with moderate coverage, the underlying edge remains fixed by wheel zeros and payout ratios. Smart bankroll limits and game selection help manage risk but cannot create a long‑term advantage.
Why choose a Column over straight-up numbers?
Column bets hit more frequently than straight-up numbers, reducing volatility. You trade the 35:1 payout for a steadier 2:1 return on 12 covered numbers, which can suit players who want smoother bankroll swings, longer sessions, and simpler gambling decisions on busy casino tables.
How can I practice Column betting safely?
Start with small stakes, track sessions, and prefer European wheels for a lower house edge.
