DEGEN Studios launches expanding-reel slot Book of Dizzy

The new title adds variable reel heights, persistent expanding symbols in free spins, and a pre-bonus gamble feature.

DEGEN Studios has released Book of Dizzy, a slot title built around expanding reels, expanding symbols and a pre-bonus gamble mechanic.

The game starts on a 5x3 grid with 10 paylines, with reels able to expand randomly to 5x4 or 5x5. A random symbol can also become an Expanding Symbol that covers entire reels when triggered, and the company said it can still pay even if non-expanded reels interrupt the sequence. Expanding Reels and Expanding Symbols can also trigger on the same spin.

In the free spins feature, three Wild Scatters trigger “Open The Book”, which keeps one Expanding Symbol active for the duration of the bonus. Four Wild Scatters unlock “Turn The Page”, expanding the reels to 5x4 and removing one symbol from the setup. Five Wild Scatters trigger “Master Spellbook”, opening the full 5x5 grid and adding the highest-paying premium symbol as an additional Expanding Symbol.

DEGEN Studios also includes a “Pre-Bonus Gamble” before free spins begin. According to the company, players can gamble to increase reel height, remove low-paying symbols, or upgrade the Expanding Symbol, with each enhancement gambled separately; a failed attempt forfeits the bonus.

Danny Gordon, Head of Studio at DEGEN Studios, said “Book of Dizzy is designed to keep messing with the reels. One spin can make the grid bigger, another can turn whole reels into the same symbol, and sometimes Dizzy throws both at you at once.

“The Pre-Bonus Gamble is where players get to play sorcerer themselves. They can make the reels bigger, clear out weaker symbols or cast a stronger Expanding Symbol into play, but every extra spell comes with the risk of losing the lot.

“By the time Master Spellbook opens, the game has pretty much torn up its own rulebook. Bigger reels, more Expanding Symbols and fewer symbols getting in the way make it feel like Dizzy has finally let all the magic loose.”
