Tiers du Cylindre means “third of the wheel” and refers to a European roulette wheel-section bet covering the section roughly opposite zero. It is often associated with a set of split bets on numbers in that wheel sector. This glossary page defines the term; for the full game explanation, read Roulette and the Glossary.
Plain Talk
Tiers du Cylindre is one of roulette’s named wheel-section bets. It does not follow the table grid. It follows the order of numbers around the wheel.
Players often call it “tiers” for short. In plain English, it means: “cover this third of the roulette cylinder.” The exact placement depends on the accepted house convention or electronic layout.
| Term | Plain-English meaning | Where it appears | Why it matters |
|---|---|---|---|
| Tiers du Cylindre | A wheel-section bet covering a third of the wheel | European roulette racetrack | Covers a named sector opposite zero |
| Tiers | Short name for the same bet | Dealer calls, electronic terminals | Common table shorthand |
| Split bet | Bet covering two numbers | Inside layout | Often used to place tiers |
| Wheel section | Group of numbers by wheel order | Racetrack diagram | Decides coverage |
Where You See It
You see Tiers du Cylindre mostly on European roulette layouts with racetrack betting. Some live casinos allow it as an announced bet; some electronic roulette terminals display it as a clickable wheel sector.
Basic rules published by regulators and casinos, including Nevada’s roulette rules of play and The Venetian’s roulette basics, explain the main roulette bet types. Named wheel-section bets are usually governed by house-specific procedures.
Why It Matters
Tiers matters because it shows the difference between table geography and wheel geography. On the layout, the covered numbers may not look connected. On the wheel, they sit in the same broad zone.
For players, the risk is cost confusion. A named bet sounds like one idea, but it can require several chips. Always check the total wager before the spin.
Example
A player asks for tiers by one unit at a table that accepts the bet. The dealer places the required split bets in the accepted pattern. If one of the split numbers hits, that winning split bet is paid; the other split bets lose.
The player is not betting on “a third” with one chip. The player is buying a bundle of inside bets.
From the Casino Side:
From the casino side, Tiers du Cylindre is handled as a known announced-bet pattern where the game offers it. The dealer must place it cleanly and repeat or confirm the bet when required by procedure.
For electronic roulette, the system calculates and displays the total chips. That reduces disputes and makes the bet easier for beginners to place, but it can also make the player spend faster.
Common Misunderstanding
The common misunderstanding is thinking tiers has a different house edge because it has a special name. Usually, the bet is just a package of standard inside bets.
The payout rules still come from the underlying bet types and roulette wheel. A French name does not improve expected value.
Hard Truth
Tiers du Cylindre may sound like refined casino language, but the cashier does not care how elegant the bet sounded. Only the chips won or lost matter.

Tiers can look compact because the dealer or terminal treats it as one named bet. But for bankroll purposes, count the chips. If the bet requires six chips and each chip is $10, the total action is $60.
