I guess this is to make people believe they are "lucky" and lure them into the BTC room.
Actually the BTC room (and also the LTC room) has a lower edge at 0.8%. The rolls you did at the FC room (1% edge) would be exactly the same in any other room, the outcome does not depend on where you play or the amount you bet.
There is no trick being applied here to make people feel lucky, it is just a room where you can play with free FakeCoins.
Is there anything unclear about that, and can I help you in any way ?
Alright, thanks for the explanation. Big difference between FC and BTC room is the max bet, but there needs to be a limit in the BTC room of course.
