Free Spins with a Random Expanding Symbol
You need a minimum of three book symbols to trigger the free spins bonus. These symbols are scatters, wilds and bonus symbols all in one. 10 free spins are awarded, regardless of whether you trigger the bonus with 3, 4 or 5 book symbols.
Before the spins start the book expands to fill the reels. The centre shows flipping pages, each with a game symbol on it. When it stops, that symbol is selected. It is now an expanding symbol for the duration of the bonus.
When a win is possible with the special symbol, it grows to cover all three spots on the reel. This will frequently connect wins over multiple win-lines. If you are lucky enough to hit your symbol on every reel, they will all expand. You now get the maximum 5 of a kind wins over all 10 win-lines.
Free spins can be retriggered with three or more book symbols.
