Triple Zero Roulette: The Odds of Every Bet on a 39-Pocket Wheel

Quick answer

Triple zero roulette uses a 39-pocket wheel: numbers 1 to 36 plus three zero pockets. Payouts stay the same as on other wheels, so every standard bet has a 7.69% house edge (3 ÷ 39), almost three times the 2.70% of a single-zero wheel. In our simulation of 1,000 spins on red, only 0.69% of players finished ahead.

Triple zero roulette is played on a 39-pocket wheel: the numbers 1 to 36 plus three green zero pockets. The payouts are the same as on any other roulette wheel, so the extra zeros go straight to the house. Every standard bet carries a 7.69% house edge, according to the Wizard of Odds, almost three times the 2.70% of a single-zero wheel.

This guide covers how the triple zero roulette wheel is set up, the exact odds and edge of every bet, and what happened when we simulated 100,000 players betting on red for 1,000 spins each.

The triple zero roulette wheel

A triple zero wheel has:

  • 36 numbered pockets, 1 to 36, split 18 red and 18 black, as on every roulette wheel.
  • Three zero pockets, commonly marked 0, 00 and 000. They are green and belong to no colour, odd/even or high/low group.
  • 39 pockets in total, each with a 1 in 39 chance on a fair spin.

That makes it the third member of the roulette family:

Wheel Zero pockets Total pockets House edge
Single zero (European) 1 37 2.70%
Double zero (American) 2 38 5.26%
Triple zero 3 39 7.69%

Our single 0 roulette wheel guide covers the 37- and 38-pocket wheels and their history.

Spotting a triple 0 roulette table

The quickest check is the betting layout. Look at the zeros above the number grid: one zero means single zero, 0 and 00 mean double zero, and a third box for 000 means triple zero. Online, the game name or rules panel should state the wheel. If a game has three zero boxes, every bet on it costs 7.69% unless the rules say otherwise.

The odds and the math

Probability on a fair wheel is favourable pockets divided by total pockets, as Britannica's guide to gambling odds explains. Roulette pays as if there were 36 pockets, so each additional zero widens the gap between true odds and payout.

house edge = 1 − (numbers covered × (payout + 1)) ÷ 39

Straight up: 1 − (1 × 36) ÷ 39 = 1 − 0.9231 = 7.69%. Red: 1 − (18 × 2) ÷ 39 = 7.69%. Shortcut: 3 zeros ÷ 39 pockets = 7.69%.

RTP (return to player) is 100% − 7.69% = 92.31%. For every 100 USDT wagered, about 92.31 USDT comes back on average.

Every bet on a triple zero wheel

The table lists every standard bet with its payout, true odds (losing pockets to winning pockets), win chance and edge, from our exact calculations.

Every bet has the same 7.69% edge. A single number wins 1 time in 39 but pays as if it won 1 in 36; red wins 18 times in 39 but pays as if it won 18 in 36.

Every bet costs about 4.99 USDT more per 100 USDT wagered than on a single-zero wheel. Our American vs European roulette comparison does the same exercise for the double-zero wheel.

Worked example: 10 USDT on red

There are 18 red pockets out of 39. A winning bet returns 20 USDT.

  • Expected return: (18 ÷ 39) × 20 = 9.23 USDT
  • Expected loss: 10 − 9.23 = 0.77 USDT per spin, or 7.69%

On a single-zero wheel the same bet loses 0.27 USDT per spin on average, and on a double-zero wheel 0.53 USDT.

What our simulation shows: 1,000 spins on red

We simulated 100,000 players per wheel, each betting 1 USDT on red for 1,000 spins, to see what the triple-zero edge does to a bankroll compared with the other wheels.

1,000 spins of 1 USDT on red, 100,000 players per wheel
WheelHouse edgeExpected lossMedian resultPlayers aheadMiddle 90% of results

Median loss after 1,000 spins of 1 USDT on red
European (single zero) 28 USDT American (double zero) 52 USDT Triple zero 76 USDT

What the triple zero results show:

  • Only 0.69% of players finished ahead, about 1 in 145. On a single-zero wheel it was 18.68%.
  • The median player lost 76 USDT of 1,000 USDT wagered, close to the 76.9 USDT the 7.69% edge predicts.
  • Even the lucky end lost. 95% of triple-zero players finished at -24 USDT or worse. On a single-zero wheel, the top 5% were at least 26 USDT up.

The more you play, the closer results get to the edge. OpenStax calls this the law of large numbers. On a triple-zero wheel, that convergence works against you faster than on any other standard wheel.

Why the triple-zero edge bites harder over time

The edge doesn't just make the average worse; it shifts the whole spread of results. On a single-zero wheel, the middle 90% of our players ranged from -80 to +26 USDT, so a fair share of sessions straddled break-even. On the triple-zero wheel, the same range moved down to -128 to -24 USDT. Variance is roughly similar on all three wheels; the triple-zero edge simply drags the whole distribution further below zero.

Strategy: what works and what doesn't

What doesn't work:

  • Betting systems. Our test of Martingale, D'Alembert and Fibonacci found each lost close to the wheel's edge per USDT wagered. Britannica notes that betting systems cannot overcome the house edge.
  • Betting on the zeros. A zero bet pays 35 to 1 and wins 1 in 39, the same 7.69% edge as any other number.
  • Covering more numbers. Your hit rate rises; your cost per USDT doesn't change.

What helps:

  • Choose a different wheel. Moving to single zero cuts the cost by about two-thirds; to double zero, by about a third.
  • Bet less in total. Expected loss = stake × spins × 0.0769. Our roulette payout calculator shows it for any bet on a triple-zero wheel.
  • Set limits first. Our stop-loss simulation shows what session limits can and can't do.

Triple zero roulette with USDT

At 7.69%, a triple-zero wheel costs more per USDT wagered than many crypto-native games. Crash and dice games built on the published 1% formula lose about 1 USDT per 100 wagered; our dice game guide shows how that works. If you play with a USDT bankroll, add network fees to the edge when you budget: on a 100 USDT session they come out of the same pot. The full house edge picture across games is in our roulette house edge guide.

Common mistakes

  • Not noticing the third zero on the layout.
  • Thinking the payouts are adjusted for the extra zero. They aren't.
  • Betting on 000 because it "covers" the new pocket.
  • Expecting a system to work better on a triple-zero wheel.
  • Comparing triple zero with other wheels by win rate per spin instead of cost per USDT wagered.

Frequently asked questions

What is triple zero roulette?

It's a roulette variant whose wheel has three zero pockets instead of one or two, for 39 pockets in total. The numbers 1 to 36 and the payouts are the same as on other wheels. The extra zeros mean more spins where outside bets lose and inside bets aren't paid fairly, which pushes the house edge to 7.69%.

What is the house edge on triple zero roulette?

7.69% on every standard bet, from a single number to red or black. It comes from 3 zero pockets out of 39: 3 ÷ 39 = 7.69%. The Wizard of Odds lists the same figure. That compares with 2.70% on a single-zero wheel and 5.26% on a double-zero wheel.

Is triple zero roulette worth playing?

On cost alone, it's the most expensive standard roulette wheel. For every 100 USDT you wager, you lose about 7.69 USDT on average, against 2.70 USDT on a single-zero wheel. Over 1,000 spins of 1 USDT the expected loss is 76.9 USDT, and in our simulation only 0.69% of players finished ahead. If another wheel is available, it's cheaper.

What are the odds of hitting a number on a triple zero wheel?

1 in 39, or 2.56% per spin. The bet pays 35 to 1, while the true odds are 38 to 1 against, so you're short three units each time. That gap is the 7.69% house edge. On a single-zero wheel the same bet wins 1 in 37 (2.70%).

Can a betting strategy beat triple zero roulette?

No. A betting system changes when you win and lose but not the edge on each bet. Our test of Martingale, D'Alembert and Fibonacci on a single-zero wheel found every system lost about 2.7% of the amount wagered, matching the wheel's edge. On a triple-zero wheel the same logic means losing about 7.69% of what you wager.
