Just made a bag of money, thought I should probably pass on my learnings...

Play roulette.

Bet 5 on black. If red wins, bet 10 on black, if red wins again, bet 20 on black, if red wins again bet 40 on black.. doubling the amount you play until you win. When you win, start over from scratch again. You won't lose any money this way..think it over if you don't understand.

You can do it with figures as high as you want, it'll still work. Just rememeber to keep track of how much you're betting and how much the betting limit is. If you run out of headroom, you can potentially lose alot of money if the odds are against you..

You'll always win, so long as you don't run out of money or hit the maximum bet limit.

Easy.

Have fun :P
