I have never played there but this is what I found.
Tigergaming used to be Gutspoker and had very slow payouts. Now rumored to be involved/related to Zerorake and Dutch Boyd. Both very bad if you are recruiting players. Also some players say when you clear the sign up bonus you have to request it instead of automaticaly getting it.
Unless things have changed, your players will hate you if any of the above is true.
