@SyGambler It is the market movement. Their boost is fixed so sometimes there is no boost at all - depend when you catch it and other the boost got even bigger when the odds dropped.
Now they started match winner boost promo where it is included in the odds so you don't have to wait to get topped manually and actually it is stated there is no max bet. But yeah even boosted they are worse than other bookies odds.
