I just cashed out from a casino and I'll get a check from them

the question is:
with a little over a hundred dollars, how should I casino whore?

of course I want to exploit the casinos for as much money as possible so I want to clear the smallest bonuses first, and then as I have enough money I can move up to the higher bonuses

the problem is I might have made accounts at different casinos a long time ago and I might not remember them all
could this cause a problem?
