Tier et Tout Strategy

The Tier et Tout roulette betting strategy was first used in the 19th century when renowned gambler Thomas Garcia employed it in Germany to great success.

The strategy is commonly used for even-money outside bets, but it can be utilized for any roulette wager due to its simplicity in nature. In this guide, we’ll demonstrate how the Tier et Tout system works, what are its strengths and weaknesses, put it to the test, and see if it’s a viable roulette strategy. Keep in mind that this strategy does require quick decision-making at times, which may intimidate novice players.

How the Tier et Tout Strategy Works

The Tier et Tout strategy is based on dividing your roulette bankroll into two distinct portions for each round. The first portion consists of one-third of the total bankroll, while the remaining two-thirds form the second portion. For example, if your initial bankroll is AU$150, the first portion would be AU$50, and the second portion would be AU$100. The bankroll total must be divisible by 3 at all times, and we’ll explain what happens if it’s not. To simplify things, we’ll only bet on even-money Black bets for this demonstration, although the strategy works with all even-money bets. This is how the basic process goes:

  • We place an AU$50 on Black (our first portion)
  • If the ball lands on Black, we profit AU$50, and our total bankroll rises to AU$200. As 200 is not easily divisible by 3, we set AU$20 aside and divide AU$180 by 3. We adjust the stake amounts to AU$60 and AU$120 and bet AU$60 on Black again.
  • If our bet loses, we wager the second portion on Black again. In our case, that would be AU$120.
  • If we lose both portions within one iteration, we adjust the starting sum to the initial bankroll of AU$ 150.
  • If we won on the second spin, our bankroll would have been AU$240, which would then be divided accordingly.

As you could notice from our example, the bankroll sometimes totals to a number that’s not easily divisible by 3. In cases like this, you should put the difference aside and divide the remaining into portions of ⅓ and ⅔. The key is to always decrease the amount to make it divisible by 3.

We’ll now see how the Tier et Tout strategy works in practice. We’ll have a hypothetical session of 5 spins, and we would use a starting bankroll of AU$90, which means that our portions are AU$30 and AU$60.

  • Step 1

    We place an AU$30 bet on Red and we lose the initial wager. For the next spin, we bet the remaining AU$ 60 - our second portion.

  • Step 2

    We bet AU$60 on Red and the bet is successful, bringing our total to AU$120. After adjusting our stakes, we start the next round with an AU$40 bet and AU$80 as our second portion.

  • Step 3

    We wager AU$40 on Red and win again, increasing our bankroll to a total of AU$160. As we can’t easily divide AU$160 by 3, we set aside AU$10 and adjust our stakes to AU$50 and AU$100. We place our wager.

  • Step 4

    Unfortunately, our AU$50 bet on Red loses. We now have to wager the second portion, which equals AU$100.

  • Step 5

    Our AU$100 bet on Red wins, bringing our total to AU$200.

For our next spin, we have to reduce our sum to a number that’s easily divisible by 3, and in this case, it would be AU$180. So, our portions would be AU$60 for the first bet and AU$120 in reserve.

Testing the Tier et Tout Strategy

To see how the Tier et Tout strategy performs in real life, we decided to put it to the test by using a simple JavaScript program that factors in several variables:

  • The session will last for 1,000 spins
  • Three players will participate, with bets of AU$ 9, AU$ 45, and AU$ 60.
  • The starting bankroll is AU$ 1,000 for each player.

Let’s see how Playey 1 did:

And this is how Player 2’s session went:

Putting Tier er Tout to the Test

Now let’s check out Player 3’s results:

Tier er Tout to the Test

As you can see from our tests, each of the three players zeroed out. In fact, none of them even made it to the 1000th spin. Player 1, which had the smallest bet size, made it to the 714th spin before zeroing out. Player 2 wasn’t as lucky, and their bankroll plummeted to zero on the 146th spin, while Player 3 only lasted 78 rounds. So, it’s evident that a bigger starting unit accelerates the crash, which means that Tier et Toute can’t be recommended as a long-term strategy.

However, what we can also see from the graphs is that the Tier et Tout strategy can work if used sparingly. Each of the three players was in profit at some point, and Player 1’s total bankroll was AU$ 2,728 at one point. Player 2’s total bankroll equaled AU4,058 around the 50th spin, while Player 3 was in a profit early on before going down.

Pitfalls of Tier et Tout

The graphs display one of the biggest downsides of this system: it doesn’t work as a long-term strategy. Moreover, if you’re starting with larger bets, it can burn through the bankroll very quickly. Experiencing two consecutive losses is detrimental to the bankroll, and the chances of that happening are above 25%.

Tier et Tout doesn’t give you any advantage over the house age, and it’s just a simple betting strategy. It also required players to access their bankroll sizes before each spin and calculate the amount of each bet, which can be confusing to new players. If you intend on using it, we suggest having a pencil, paper, and a calculator next to you.


The main conclusion from this Tier et Tout guide is that it's not effective as a standalone strategy, and that’s especially true for long sessions. However, if you use it from time to time and you're able to correctly time your exit, it has the potential to generate decent profits, especially if you start with a substantial bankroll. Although Thomas Garcia once used this system successfully at a casino, it's primarily attributed to luck. Nevertheless, it's important to note that using this method exposes you to the risk of rapidly depleting your bankroll.

Despite being more complex than other common betting methods, Tier et Tout is relatively simple. If you have quick thinking abilities and can keep track of your bankroll's changes, you can enjoy testing this system through a free online roulette game.
