Girevik Eurobet shares their ring tables with
Partypoker, EmpirePoker and a few other sites so its practically the biggest online poker site. If you play on Party and i play on Eurobet we can play on the same table.
The only differences are the lack of MTT's (dont know about SnG's) because they dont share them with Party so they dont have traffic and the very bad idea of having online cashier.
If someone plays on Party or Empire without rakeback he is dumb if he doesnt sign up.
To clear the bonus you just have to get dealt a hand that results in a raked pot (it doesnt matter when/if you fold). I think you have to play 10 times X your bonus amount in hands (not sure though).
Edit: 10 times X your bonus amount.
