Razor Shark is one of my favorite slots game that I'll never missed to play although only few tens spins.
Let him try.
At least he will know the reality once he experience by him self before he see a big win from other user. He will think, f*ck these is hard to hit the bonus while he playing on top slot from (Relax, Push, and other).

Interesting. In the past I used to think that Pragmatic Play slots were not that rewarding. My wins on those slots were always below 50x, but then one day I won this

on Twilight Princess by Pragmatic Play, and it was my personal record 1,172.75x of my bet

and I've changed my mind. I'm not winning anything big since then, but at least I know, Pragmatic slots can deliver.
