Easy,
Go for the jugular, take 1 5c spin on "Sonic Boom".
If you win, take it to Munchkins at 15c per spin, or play 9 lines at 9c per spin.
Then move to Thunderstruck if you get the biscuits & free spins (if I have left you any that is

).
Thunderstruck is partial to dispensing 5 Rams, try to convince the slot you are a Weatherman

If you hit something here, this could get your 7c up to enough to make min cashout, and really p1ss off the casino.
PS - If you can, leave another 7c behind after you cash out
