Thomas Donald Roulette Strategy

Thomas Donald Roulette Strategy

The Thomas Donald strategy is one of the most respected betting systems for roulette fans. This strategy allows gamblers to receive good profits using simple algorithm of betting. The main idea of the Thomas Donald is to increase bets every time you lose and decrease every time you win. It is crucial to play even money bets like red/black, 1-18/19-36 etc. So, if you lose you need to increase your bet by 1 coin. If you win you should decrease your bet by 1 coin. Everything is extremely simple. Let’s try to calculate how much can you win with such system. Ok, let’s say that there were 37 rounds of the game. You always placed bet on red. Alright, from 37 spins there were 18 reds, 18 blacks and 1 zero (most typical scenario according to the theory of probability).

Now we can draw a simple table to make the situation more understandable:

round outcome Bet win/loss Balance
1 red 1 +1 +1
2 red 1 +1 +2
3 red 1 +1 +3
4 black 2 -1 +2
5 black 3 -2 0
6 black 4 -3 -3
7 red 3 +4 +1
8 red 2 +3 +4
9 red 1 +2 +6
10 black 2 -1 +5
11 black 3 -2 +3
12 black 4 -3 0
13 red 3 +4 +4
14 red 2 +3 +7
15 red 1 +2 +9
16 black 2 -1 +8
17 black 3 -2 +6
18 black 4 -3 +3
19 red 3 +4 +7
20 red 2 +3 +10
21 red 1 +2 +12
22 black 2 -1 +11
23 black 3 -2 +9
24 black 4 -3 +6
25 red 3 +4 +10
26 red 2 +3 +13
27 red 1 +2 +15
28 black 2 -1 +14
29 black 3 -2 +12
30 black 4 -3 +9
31 red 3 +4 +13
32 red 2 +3 +16
33 red 1 +2 +18
34 black 2 -1 +17
35 black 3 -2 +15
36 black 4 -3 +12
37 zero 5 -4 +8

According to our table we have won 18 times and lost 19 times. At the same time we managed to have 8 coins profit! Surely if we were luckier we could win even more.

Now you might start thinking that using of the Thomas Donald system is the guaranteed way to make profits playing roulette. But we have to disappoint you. There is no guaranteed winning strategy. And the Thomas Donald system has got its own cons. First of all you should know that this strategy is extremely good for high-rollers. Thus if you are lacking money you should avoid using the system. Experts say that your bankroll has to be as big as 3000 initial bets. Therefore if you place $1 bets you need to have $3000 on your account. Probably not so many gamblers can afford to risk $3000. Another problem of the Thomas Donald system is that it will generate profits only in case of even outcomes. But let’s assume that your bet won only 10 times from 37 spins. In this case you will lose quite much. Therefore the Thomas Donald system cannot guarantee positive result.
