Don't be afraid. hahaha. For starters try the play'n go slot games. This provider makes me addicted to playing slot due to its good return compared to another provider.
Yeah, try Play N' Go, my approach is just spinning 50 spins on every slot, if it spawns a free bonus early, i'll hop on another slot, since Play N' Go tends to eat bankroll after too many spins. My number of bets is 50 auto spin, if it does not hit the bonus round I'll try another 20 and then 10 auto spin, then change slots whether I hit the bonus round or not. As I stated Play N Go has a tendency of eating your bankroll if you stay in a single slots for too long. Aside from that, if you happen to get a bonus after hundreds of spins, there is a tendency that the reward will be shitty. So I think it is not worth grinding to get the bonus round in Play N Go.
