i would do what the other guy did. if you dont need the 100 then thats just extra cash. id save 50 to buy weed and shit, then spend the other 50 on tickets. wether they be $1 $5 or mix of both. see what you get. always save 50 of you winnings and then if you dont get 50, or indeed the level you set stop playing.

thats my rule when ever i go to a casino, i set my stake and once i make that back i keep it so i always win, then i play with the money the rest of the night always pocketing after a certain level to ensure that the house doesnt win

peace
