Well I found something that may interest you all. Its a very good bet but u have a 50% chance of losing it all.

Its for golden palace I believe but its 200% match on your 100 deposit so you got 300. The trick is you cant withdraw that 200 ever - they deduct 200 from your first withdraw so if you have 199 and withdraw you dont get shit - if you have 201 you only get 1$

Well even with this there is still a huge advantage to this assumming the roulette wheel isnt rigged.

Simply deposit 100 - bet 300 - if you win your up 300 (like 48% chance of winning or something if you bet on odd or even or red or black) - so you are risking 100 to win 300 on basically a 50 50 bet - anyone gonna do it.
