Bonus Features of Book of 99
The bonus features of “Book of 99” add depth and excitement to the gameplay. Here’s a detailed look at each feature:
Wild Symbol: The wild symbol in “Book of 99” functions like in many slots, substituting for all symbols except the expanding symbol during the free spins. It plays a crucial role in activating the free spins feature, offering a greater chance to trigger this lucrative phase of the game.
Free Spin Feature: To activate the free spin feature, you need to land 3 or more wild symbols on the reels. Upon activation, one of the pay symbols is randomly selected to become an expanding symbol for the duration of the free spins. This feature is central to the game’s high potential for big wins.
Expanding Symbol: This special symbol becomes active only during the free spins. It is selected at the start of the free spins round and has the ability to expand over a reel, creating more opportunities for winning combinations. The expanding symbol enhances the chances of securing significant wins during the free spins. However, it reverts to its regular function once the free spins round is over.
Collection Feature: Unique to “Book of 99”, the collection feature is triggered by landing wild symbols. Each wild symbol landed increases a collection meter by one. When the meter reaches 99, it activates the free spin feature. This special version of the free spin feature comes with an added advantage: it increases the bet without additional cost to the player!
Max win at Book of 99
To attain the maximum win in “Book of 99”, which is 12,075 times the stake, players need to leverage the game’s bonus features effectively. The key is in the free spins round. During this round, a symbol is randomly chosen to become an expanding symbol. If this symbol is one of the higher-paying ones, and it covers all the reels, it can lead to substantial wins.
Maximizing wins involves getting full-screen expansions of high-value symbols during the free spins. Since the game has high volatility, such large wins are rare but possible. Consistently triggering the free spins, either through the collection feature or by landing wilds, increases the chances of hitting the max win.
