Tiers du Cylindre is a roulette call bet that covers 12 numbers on the side of the European wheel opposite zero. It is usually placed as six split bets. The name sounds advanced, but the math is simple: it is wheel-sector coverage with the normal single-zero roulette house edge.
Quick Facts
- The name means “third of the wheel.”
- Tiers covers 12 numbers.
- It sits opposite the zero section on the European wheel.
- Common placement uses 6 split bets.
- Each split pays 17 to 1 if it wins.
- It is common on racetrack layouts.
- Standard single-zero house edge is usually 2.70%.
Plain Talk
Tiers du Cylindre is the cleanest major call bet because it is built from six split bets.
Instead of covering the zero neighborhood like Voisins du Zéro, Tiers covers the opposite side of the wheel. Players often use it when they like the idea of covering a physical wheel section but do not want the larger 9-chip Voisins package.
The bet still does not create an advantage. It covers 12 numbers out of 37. When one of those numbers lands, one split bet usually wins. When any other number lands, all six chips lose.

How It Works
The common Tiers du Cylindre numbers are:
| Wheel sector | Numbers commonly included |
|---|---|
| Tiers du Cylindre | 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33 |
The usual layout placement is six splits:
| Split bet | Numbers covered | Common payout |
|---|---|---|
| 5/8 | 5, 8 | 17 to 1 |
| 10/11 | 10, 11 | 17 to 1 |
| 13/16 | 13, 16 | 17 to 1 |
| 23/24 | 23, 24 | 17 to 1 |
| 27/30 | 27, 30 | 17 to 1 |
| 33/36 | 33, 36 | 17 to 1 |
Roulette table rules and approved wagers are controlled by the house and regulator. You can compare public procedures in the Nevada roulette rules of play and the Massachusetts roulette rules. For a broader summary of roulette probability and house edge, see the Wizard of Odds roulette basics.
Why Tiers is easy to misunderstand
Tiers covers about one third of the wheel, but not exactly one third in a fair-price sense.
| Item | Count |
|---|---|
| Covered numbers | 12 |
| Total European pockets | 37 |
| Uncovered pockets | 25 |
| Chips used | 6 |
| Winning chip type | Split |
The bet often feels clean because every chip is a split. That makes settlement simpler than Voisins or Orphelins.
Roulette Table Example
A player places Tiers using 10-unit chips. Six split bets are placed, so the total wager is 60 units.
| Spin result | Settlement | Result idea |
|---|---|---|
| 30 lands | Split 27/30 wins | One 10-unit split pays 170 units profit |
| 8 lands | Split 5/8 wins | One 10-unit split pays 170 units profit |
| 0 lands | No Tiers chip wins | All 60 units lose |
| 21 lands | No Tiers chip wins | All 60 units lose |
A winning Tiers spin looks dramatic because a split pays 17 to 1. But five other split chips lose at the same time. The net result is not the same as one isolated split bet.
From the Casino Side:
Tiers is dealer-friendly compared with some call bets. The standard pattern is six splits, and trained roulette dealers know it quickly.
The operational risk is still timing and clarity. A player must have the value available, the dealer must repeat or confirm if house procedure requires it, and the chips must be placed before betting closes. If the table is busy, Tiers can be one of several racetrack bets hitting the layout at the same time.
Floor supervisors also watch whether players understand minimums. A 5-unit table minimum does not always mean a 5-unit total Tiers bet. It often means each required chip must meet the unit value accepted by that layout or terminal rule.
For the casino, Tiers is useful action: six chips, simple settlement, normal edge.
Common Mistakes
- Thinking “third of the wheel” means the bet wins one third of the time exactly.
- Forgetting the total stake is six chips.
- Comparing the 17 to 1 split payout without subtracting losing chips.
- Believing the opposite side of zero is “due” after zero-side results.
- Using Tiers as a wheel-bias guess without real evidence.
- Confusing Tiers with dozens or columns on the layout.
- Assuming all online roulette games offer the same racetrack options.
Hard Truth
Tiers is not a discount on roulette. It is six split bets wearing a smarter jacket.

Deeper Insight
Tiers is popular because it gives order to randomness. The player is not scattering chips across the whole table. The player is making a neat wheel-sector decision.
That can be a good entertainment choice. It is not a mathematical improvement.
Tiers also teaches a useful lesson about payout illusions. A split pays 17 to 1, which sounds strong. But Tiers is six split bets, not one. If one split wins, the other five lose. So the player must look at the package result, not just the headline payout.
The same logic applies to many roulette systems. Players remember the winning part of a bundle and mentally discount the losing pieces. Casinos do not discount them. Every chip is counted.
If you play Tiers, play it because you like that wheel section and understand the stake. Do not play it because the name makes the bet feel smarter.
Formula / Calculation
Coverage probability:
P(Tiers hit) = 12 / 37 = 32.43%
Expected loss for a 6-chip package on a single-zero wheel:
Expected Loss = Total Amount Wagered × House Edge
With 10-unit chips:
Total wager = 6 × 10 = 60 units
Expected loss = 60 × 2.70% = 1.62 units per spin
Formula Explanation in Plain English
Tiers covers 12 of the 37 pockets, so it should hit about 32.43% of the time over a huge sample. But every spin costs six chips. The house edge applies to the full amount wagered, not to the name of the bet.
