Since each bonus is viewed separately, the site will automatically prioritize which bonus you are playing through. This may mean your play is not actively counting towards the most recently activated bonus.
When multiple bonuses are activated your play will count towards one bonus at a time, play will not start counting towards your next bonus until:
The wagering requirements of the first bonus are met;
The bonus funds from the first bonus have been depleted; and
The active bonus is forfeited.
