Hello Tollens,

Good question.

Roulette is an exceptionally well balanced game and that's one of its many charms.

No method offers an "advantage" in the sense of "being better than the other", but they do offer different risk-reward parameters. To put it philosophically, **you cannot turn the odds in your favor, but you can still use a strategy**.

Let's take these 3 scenarios:

1) Bet 4 units in 4 different numbers for 1 spin

You have 4/37 (~11%) 27chance of winning 32 units (total 36) 5,4

You risk the loss of 4 units.

2) Bet 4 units on 1 number for 4 spins

Your chance of winning at least 1 bet is 1-(36/37)(36/37)(36/37)(36/37) = ~10,5%

But in this scenario you can win on the first spin, in which case you only risk 1 unit instead of 4. Or you could win multiple times (up to 4 times) if you were extremely lucky. So the chance of win in this scenario is slightly less than the previous, but offers some extra benefits.

3) Bet 4 units on the same number

Your chance of winning is 1/37 =~2,7% , but in case of a win you gain 140 units! (total 144)

You risk the loss of 4 units.

The conclusion is that there are no better or worse bets on European roulette. There are only strategies, and we can decide our bets to fit our strategies....
