Tier et Tout Roulette System — Simple Guide, Examples & Real-World Risks (UK)
Tier et Tout is a 19th-century staking plan that splits your bankroll into one-third and two-thirds and adjusts after each result.
It’s fast to run and works on any roulette bet, but most players use it on even-money (Red/Black, Odd/Even, High/Low).
Below is the clean, modern version—Otto’s steps, a 5-spin example, traps, and smart stop rules.

Tier et Tout — What It Is
- Split your current bankroll into ⅓ (first portion) and ⅔ (second portion).
- Bet the first portion. If it wins, add the profit to your bankroll.
- If the first bet loses, bet the second portion next spin.
- After the second spin (win or lose), recalculate the bankroll. If it isn’t divisible by 3, skim a small amount aside so it is, then split again into ⅓ & ⅔ and continue.
- Common use: stick to French (La Partage) or European wheels on even-money bets.
Quick Start (1-Minute Setup)
- Pick a base session bankroll that’s comfortable (e.g., £90, £180, £300).
- Divide by three → make two stacks: ⅓ and ⅔ (e.g., £30 / £60).
- Choose a single even-money bet (e.g., Black) and stick to it.
- Run the sequence: first portion → if lose, second portion → then recalc & split.
- Use stop rules (below). Celebrate small wins; walk on peaks.

Tier et Tout Example — £90 Bankroll on Black (European Wheel)
Start: £90 → split to £30 / £60. Bet Black every spin.
| Spin | Portion Bet | Stake | Outcome | Session Bankroll | Next Split |
|---|---|---|---|---|---|
| 1 | ⅓ (first) | £30 | Lose | £60 | — |
| 2 | ⅔ (second) | £60 | Win | £120 | £40 / £80 |
| 3 | ⅓ | £40 | Win | £160 | Adjust to /3 → skim £10 → £150 → £50 / £100 |
| 4 | ⅓ | £50 | Lose | £100 | — |
| 5 | ⅔ | £100 | Win | £200 | Adjust to /3 → skim £20 → £180 → £60 / £120 |
Skimming is just parking a small amount aside so the remainder divides cleanly by 3. You can pocket it or keep a “side pot.”
Bankroll & Table Limits
- Pick a session size you can repeat—e.g., 30–100 base units.
- Check table max: the second portion (⅔) must always fit under limits, even after a few wins/losses.
- Set gates: stop-loss (e.g., ⅔ of session) and stop-win (e.g., +⅓ or +½ session). Walk on either.
- Prefer single-zero wheels; French (La Partage) is best for even-money bets.

Reality Check — Consecutive Losses
On European even-money, a single spin loses about 51.35% of the time (includes 0). Losing two in a row happens roughly 26% of the time. Plan for that.
Pros
- Very easy rhythm (⅓ then ⅔; resplit)
- Fits any roulette bet (best on even-money)
- Skimming creates “lock-in” moments
- Clear, mechanical next bet—no guesswork
Cons
- Doesn’t beat the house edge long-term
- Two quick losses can drain a session fast
- Frequent resplits + skims require focus
- Table limits cap recovery after bad runs
Traps, Tests & Smart Use
- Not a profit engine: Tier et Tout structures stakes; it doesn’t change odds. Use stop-win/stop-loss.
- Short bursts work best: 15–25 minutes; bank a skimmed “side pot” and reset.
- One bet only: stick to your chosen even-money—switching mid-sequence adds noise.
- Start small: test the cadence on European / French (La Partage) then scale.
Tier et Tout — FAQ
Is Tier et Tout good for beginners?
Yes—once you learn the ⅓ / ⅔ cadence. Use tiny stakes first and practise on single-zero wheels.
Which bets should I use it on?
Any bet works, but even-money keeps swings manageable. French (La Partage) improves even-money value.
What bankroll should I start with?
Pick a session that splits cleanly into ⅓ and ⅔ (e.g., £90 → £30/£60). Ensure the ⅔ bet fits table limits.
Can Tier et Tout beat the house edge?
No system can. It’s a staking plan. Use it to structure play, not to guarantee profit. Stop on peaks.
What if my bankroll isn’t divisible by 3?
Skim a small amount aside until it is. Keep a “side pot” so the running stack divides cleanly every resplit.
