Bonus Rounds & Free Spins

There are 2 ways to start the free spins round. The first is to get 3 book symbols to appear on the reels, and you’ll get 10 free spins. During this round, a random character becomes an expanding symbol. When it appears, it’ll expand to fill all of the reels and pay as a scatter would. This round can re-trigger by landing 3 more wild symbols.

Once you have 99 wilds, the free spins round will start. A random symbol becomes an expanding character. Once you finish your spins, the meter will reset.
