Once you collect the Progressive Bonus 4 times, you unlock one free spin on the Mega Wheel. Spin the wheel to automatically receive the Mega Bonus.

By the way - the prize you get is calculated based on two things:

• The value of the prize that the wheel has landed on.

• The amount of Facebook friends you have who also play LOTB.

So the more you play, and the more Facebook friends you have in-game - the bigger the prize will be!
