The Sticking Reels & Enlarging Symbol: The Core of the Game
This is where Book of Oz earns its keep. Land three or more Book scatter symbols on the reels, and you start the free spins round. You begin with 6 spins. Before they begin, the game chooses one regular symbol to serve as the special expanding symbol. Whenever that symbol appears on a reel during the bonus, it grows to cover the whole reel and remains there for the duration of your free spins. If you land more of that same symbol, it causes a re-spin and sets your spin counter to 6. This can create a chain reaction. Reels stick one after another, and the screen can be covered with the same high-paying symbol. It’s a thrilling, intense mechanic that can turn a single trigger into a major payout.
