Golden Tiger Casino - can someone explain this part in the T & C's!?

I recently recieved a letter and a cd in the post, promising me �1500 play money to use within an hour, and after the hour if the balance was over �1500 i could withdraw my winnings (max �200). However, after i had won �147.75, i was told that i would get my money in the form of a bonus, and i would get �10 at a time, after i had wagered 10x this bonus amount. So, to recieve my full bonus, i would have to wager at least �1477.50, depending on which game i was playing. Very misleading, and a bit out of order. Don't use these guys, there's much better bonus schemes out there!!!
