They ask you to deposit $100 and they will give you $100 bonus. You must wager $1800 or more. After that, if your balance has, say, $100 left, they say this is their bonus. You can only withdraw 25% or $25. The other $75 must stay in the accout. Further, you have to play with the $75 and you only have one chance to withdraw money above $75, if you can get the balance above $75. After that withdrawal, the $75 disappears. Is this a bonus or a trap? Feedback appreciated.
