System 1

It relies on a simple chance (black, red, even numbers, odd numbers). If you lose you will double the amount on the same field.  Example: It is 1 euro to “red” when “Black” wins you just put 2 euros on the “Red”. Now, when “Red” wins, you won 1 Euro (3 Euro in total were played and you get the use and profit, ie 2 2 euros). If Black wins again but you just put 2 times the last use, ie 4 euros. Win it now, you get a total of 8 euros (Profit).

This system is based on the probability, ie on average, would have at 10 roulette casino games 5 times red and black to win 5 times.

System 2

The same system as the system 1, but it tripled the amount if you lose until you win.
Example: It is a euro set on Black – Red wins. Then set back 3 euro on Black – Black wins. One gets then 6 euros.

System 3

It is easy chances as black, red, even numbers or odd numbers. Every time you win if you doubled the use and every time you lose, you halve the amount in the betsson casino.
