I've been playing (without real money, of course!) Roulette online using the "Roulette Advanced Strategy" that has been mentioned here before. It's at: http://mycasinostrategy.com/ I haven't played 100,000,000 trials, but so far it's worked pretty well, IF I stop when I win, like you're supposed to. Anyway.... the chart stops at 20 spins, with a bankroll of $3450. Does anybody know how this chart could continue for, say, 30, 40, 50 or more spins? I can't find any pattern in how those bet sizes are increasing. I get the impression it's sloppily calculated, and could be much better. Those increases in bet size, in percents, look like: 200 66 40 86 62 67 69 69 Very bizarre, especially the 40 and the 86, but it's fascinating to play with this... another point is that because each spin is independent, you don't need to use the same 7 numbers each time, another reason I suspect this is sloppily calculated.
