So this is my strategy that seems to work pretty well for me. Assume 100 units (I've done this with $1, $5 and $25 chips) 4 units on ten numbers straight up 20 units on 3 columns that have 3 numbers not included in any of the straight up numbers This covers 19 numbers on a 37 number wheel assuming only 0. The odds of winning are greater than 50%. A win on a straight up number gives a 44% return. A win on a column gives a 140% return. If these were the odds on a slot machine everyone would be playing it. Now use my strategy to win!
