Book of Crown Free Spins
The free spins round is where Book of Crown earns its 5,000x ceiling. Here's exactly how you trigger it, why the one expanding symbol the game picks decides everything, how retriggers work, and when the Bonus Buy is worth it. Want to know who we are? Read about our Book of Crown coverage.
The base game is the warm-up. Almost all of the big potential in Book of Crown lives in the Free Spins round, so this is the part worth understanding before you spin for real.
How to trigger the round
Land 3 or more Book of Crown symbols anywhere on the 5×3 grid and the Free Spins round begins. The Book is both wild and scatter, so it does not need to sit on a payline to count. Three books is all it takes, and because they pay as scatters you often bank a small win on the same spin that unlocks the bonus.
The expanding symbol is the whole game
Before your free spins play out, the game picks one special Expanding Symbol for the round. That single choice sets the tone for everything that follows. Whenever the chosen symbol lands, it stretches to fill its entire reel and pays from any position, not just left to right along a payline.
Get a high-value symbol as your pick and a run where it keeps landing, and full reels of it stack into the kind of hit that reaches the 5,000x maximum. Draw a low-value symbol, and the round pays more modestly. There's no skill to it, but it is the reason two players can hit the same bonus and walk away with wildly different results.
Retriggers and Bonus Buy
Land 3 or more Books again during the round and you retrigger it, adding another batch of spins on top with the same expanding symbol still in play. A couple of retriggers can turn a quiet start into a serious total.
If you would rather not grind the base game waiting for three books, the Bonus Buy drops you straight into the Free Spins round for a fixed price. It costs more per attempt, so treat it as a faster route to the feature rather than a shortcut to profit. As a medium-volatility slot, Book of Crown keeps the swings sensible either way, but bankroll discipline still matters.
