now i've experienced a very funny thing.
i used now a bonus (60%) because i got an email that i'm now a VIP silver player, so i tried the bonus out and guess what, since that i have so much playtime and i got so many bonus rounds, so i made only a $20 deposit and got a full balance of $32 and could wager a little bit about $500 but then i certainly lost the money.
but that was not all, because after that i used my 2nd bonus, which was also a 60% and started again with a $32 balance, after depositing my $20 and could again wager about $500 and have a playtime about some hours before i busted out, so why does this now only happen, when i use a bonus and not, when i make deposits which are much higher and with my own money, without any bonus?
but it's certainyl again only randomness
