to back six numbers pick two out of each dozen.the nearer to each other the better. even money bets one unit if a win put two units on the next even money bet you are now winning three units. or losing three. if winning go back to one unit. if losing put two units on a even money. let it ride if a win. you are now winning three units or losing five. if losing. put three units on a even money and so on. the best numbers for the six are8.11.23.13.30.36. i suggest you wait till these numbers have not played for a while and then start playing.
