Roulette the divide rule

write 1 and bet 1u to ec [lose] next spin
write 2 and bet 1u to dozen [lose] so the debt now is 2u so divide it so we have 2 debts of 1u+1u so we have 2 players with debts 1u---1u so next spin one of 2 players bet so

write 2---[1] and bet 1u to dozen [lose] so next spin
write 3---[1] and bet 1u to line [lose] so next spin 2 players bet so
write 4---2 and bet 1u to line and 1u to dozen [dozen wins] so 2=0 so we have 1 player with debt=4 so next spin

write 5 and bet 1u to line [lose] next spin
write 6 and bet 1u to corner [lose] so now divide 6/2=3+3 so now we have 2 players with debts 3---3 so next spin one player bet so

write 4---[3] and bet 1u to line.......etc if you understood the mechanism make your own strategy just be carefull after dividing 1 player bet next 2players next 3players .....etc see an example
