The £150 roulette system is called after the amount of money usually placed with this system.
1.) Bet £50 on the first dozen (1st 12). Your odds are 1 to 3.
2.) Bet £50 on the second dozen (2nd 12). Your odds are 1 to 3.
3.) Bet £5 on 10 random selected numbers from the third dozen (3rd 12). Your odds are 1:35 on each number.
If you take a look at the following sheet you can see, that the bets cover all your numbers except the zero and 2 numbers from the third dozen. If you won in the first or second spin, then your winning was £150 so you made a profit of £100 or £50. If you won in the third round then your winning was £180 so you made plus £30 overall profit.
