Our Tips for Using the Prime Slots Casino Bonus
Stick to slots with high RTP while clearing wagering — games around 96% and above keep more of your balance in play.
Use the free spins first, on the named game, before you touch your own balance — they expire on their own clock.
Respect the max bet while a bonus is active; most terms void the bonus and its winnings if you exceed it.
