I did some play using "high bets", but it is not as it looks. On a wheel there is no house advantages we can put a load of chips and there is no chance we lose all in a spin.
I set it so we win 0.5 or 0.1 every spin except two numbers there it cost 1.1 each hit.
On every loss, I slowly increase the risk on those numbers and increase the pay out on two other numbers, and when I got a hit there all loss went and a decent plus.
The turnover is large 7336 Euro, but I had only 300 in the bank. Every spin was bet by 10.9 Euro all the time, but with different distribution. WORKS ONLY IF NO HOUSE ADVANTAGES.
It was 673 spins and 101.15 plus, a 33% 0f the used bankroll. Down at most 40 Euro.
