>>10496841if you mean 10 minutes of actual play time, not counting the time to turn your money into chips and to walk between tables:
i'd say put it on 1 number on roulette, if you win you'll have 3,600.
then find the high limit area and put that on 1 number, if it hits you'll have 129,600.
now find even higher limit tables (e.g. caesar's spreads roulette that you can bet up to 50k on) and you have some options. one is to split your roll into 4 parts of 32,400 each, put them on 4 numbers. if any of them hit you'll have 1,166,400.
overall odds roughly 0.025*0.025*0.1 = 0.00006, which is 0.006% (it would take you an average of ~16,667 tries to win once)
if you mean 10 minutes from walking into the door (like a mob thug is on your ass and you need to come up with a million before he blows your kneecaps out), you really have no options. run to the jackpot slots and pray to hit a quick million. odds are like 1 in 10-50 million depending on the casino
