Tier et Tout Strategy

Last updated: 03.13.2023 by Andrew Shepard

Tier et tout is a roulette betting strategy that was devised in the 19th century by a famous gambler named Thomas Garcia. It became quite popular after Garcia employed the tactic with great success at a German casino.

While Tier er Tout is typically used on even-money outside bets, it can be applied to any roulette bet. As you will find out in this tutorial, Tier er Tout is pretty easy to understand. However, it requires some quick thinking which might scare off newer players.

How Tier er Tout Works

The main idea of Tier er Tout is that you start by dividing your bankroll into two parts. One-third of the bankroll is the first portion, while the remaining two-thirds make up the other. So, if you hit the roulette table with $90, then the first part is $30, and the second portion is $60. The key is that your bankroll total is always divisible by 3. To keep it simple, we will only wager on even-money Red bets. So, here’s the general flow:

  • We wager $30 on Red.
  • If we win, we profit $30, bringing out a bankroll up to $120. Conveniently, $120 is divisible by 3. We adjust our stake amounts to $40 and $80 and repeat the process on the next spin.
  • If our first spin loses, then we wager the remaining $60 in the next spin.
  • If we lose 1\3 and 2\3 within one iteration, we play the next spin with an initial sum of 90.
  • If our second spin is a winner, we also end up with a $120 bankroll which would then be divided accordingly.

When using Tier er Tout, you will sometimes end up in a situation where your bankroll totals something like $160, which isn’t divisible by 3. In a case like this, you would put $10 aside and divide the remaining $150 into portions of $50 and $100. That is, we will always decrease the amount in order to make it a multiple of 3. You then simply repeat the same process.

Let’s see how it works in practice using an imaginary session of 5 spins. We will assume we have a starting bankroll of $90 which means our bet progression will start at $30 and $60.

  • Step 1

    We wager $30 on Red and lose. We need to bet the remaining $60 on the next spin.

  • Step 2

    We wager $60 on Red and win. We now have $120, which means we have to adjust our stake amounts. We start the next iteration with a $40 bet and $80 in reserve.

  • Step 3

    We place $40 on Red and win again. With the $40 gain, our bankroll is now at $160. Because $160 isn’t divisible by 3, we put $10 aside and set the stakes at $50 and $100. We will wager $50 next round.

  • Step 4

    We wager $50 on Red and lose. We have to wager the remaining $100 next round.

  • Step 5

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

So, how much do you think you have to stake on the next spin? If you guessed $60, then you are correct. Yes, we had $200 in our bankroll after the fifth spin, but don’t forget that according to this system, we reduce our sum so that it is divisible by 3; in our case, it is 180.

We end up with a $60 stack and a $120 stack for the next cycle.

Putting Tier er Tout to the Test

Let’s put Tier er Tout to the test. We will use a simple JavaScript program which factors in:

  • A 1,000-spin session
  • Three players staking bets of $9, $45, and $60, respectively.
  • All three players start with $1,000 each.

The results for Player 1 are graphed below.

Here’s how Player 2 fared:

…and finally, Player 3’s results:

Tier er Tout to the Test

It’s pretty easy to see that Tier er Tout has a negative effect on your bankroll as none of the players in our simulation completed the full 1,000-round session. Player 1 lasted the longest, making it all the way to the 714th move, while Player 2’s bankroll bottomed out on the 146th move. Player 3, the biggest bettor, only lasted 78 rounds. We also see that a bigger base unit greatly accelerates the crash.

While we can’t recommend Tier er Tout as a long-term strategy, the graphs show that the system can be effective if used sparingly. Each player in the simulation was playing with house money at some point and could have walked away with impressive profits had they called it quits in a timely manner. Player 1 was up $1,728, while Player 2 was up $3,058. Meanwhile, Player 3 was up a couple of hundred dollars early on. We also see several other positive spikes.

Pitfalls of Tier er Tout

One of the most significant downsides to Tier er Tout is illustrated in the above graphs. It simply doesn’t work as a long-term strategy. On top of that, it can burn through a bankroll very quickly especially if you are starting with larger bets. However, an even bigger issue lies in the fact that two consecutive losses will decimate your bankroll. If you are using the Tier er Tout system on even-money outside bets, the chances of losing two in a row are slightly above 25%. Tier er Tout is just a betting strategy. It doesn’t give you any advantage over the house edge.

One last thing that you should keep in mind is that Tier er Tout requires players to constantly assess their bankroll sizes and calculate the amount of each bet. If you are new to this system and plan to give it a try, you might want to consider having a pencil and paper on you.


The most significant takeaway from this Tier er Tout guide is that the system isn’t effective when used exclusively in long sessions. On the flip side, using it intermittently can yield decent profits if you time your exit just right. This is especially true if you are fortunate enough to have a big starting bankroll. Even though Thomas Garcia once used the system successfully at a casino, it’s safe to say that luck was on his side. Again, those who use this method are always at risk of quickly depleting their bankrolls.

Despite being a little more complex than other popular betting strategies, Tier er Tout is quite basic. If you can think on your toes and stay on top of every shift in your bankroll, you can have a lot of fun experimenting with this system playing a free online roulette game.
