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).
After that,
he will move to pragmatic play again ~xd
Interesting. In the past I used to think that Pragmatic Play slots were not that rewarding. My wins on those slots were always below 100x, 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.
I think that is why you are wrong,normally it depends on the slot but lately Pragmatic Play have been really really bad as slots people are struggling in all casinos to hit something decent with them.I don't know what happened to them but to me it looks to win huge in Pragmatic slots nowadays is much harder than passing a difficult math test.
I personally have shifted view and got back to Play n Go,I usually play 30-50 dollars and I feel better knowing I have played my chances better as the bonus there will fall within such range playing with minimum bet of 0.10 while in Pragmatic slots even catching the bonus in base spins is becoming mission impossible.F*ck them as the worst provider for me.
