DEGEN Studios announced Book of Dizzy on 10 November 2026, a slot whose reels can grow from a 5x3 grid to 5x5 and which adds a gamble before its free spins bonus.

The release follows the studio's Loot Box Legends launch on 4 November, making Book of Dizzy its second new slot in a little over a week. The studio describes itself on its homepage as a developer of high-volatility slots.

How the Book of Dizzy reels expand

The game opens on a 5x3 grid with 10 paylines. A payline is a line across the reels on which matching symbols must land to pay. On any spin the reels can expand at random, and the payline count rises with the grid.

GridPaylines
5x3 (starting grid)10
5x415
5x520

A second feature, the Expanding Symbol, is chosen at random. It stretches to cover whole reels, and a win still pays when reels without the symbol sit in the middle of the sequence. That removes the usual requirement that a winning run be unbroken from the left. According to DEGEN's game page, Expanding Reels and the Expanding Symbol can both trigger on the same spin, so a spin can combine a taller grid with full-reel symbols.

G3 Newswire reports a maximum win of 10,000x the stake.

Free spins: three modes tied to Wild Scatter count

The bonus round is triggered by Wild Scatters, symbols that act as both a scatter (a symbol that pays or triggers features regardless of position on a payline) and a wild. The number landed decides which version of free spins the player gets.

5Master Spellbook

The three modes give the bonus a tiered structure, with five scatters reaching the top mode directly rather than only adding spins to the base one.

The Pre-Bonus Gamble

The most distinctive mechanic sits between the trigger and the free spins. In the Pre-Bonus Gamble, a player can try to improve the coming round in one of three ways:

  • raise the height of the reels;
  • remove low-paying symbols;
  • upgrade the Expanding Symbol.

Each enhancement is gambled separately, and a failed attempt forfeits the bonus, according to the company's release as carried by EEGaming and G3 Newswire. The feature turns the bonus entry into a risk decision, which suits a studio that positions itself in the high-volatility segment. Operators and players weighing the game should note that the downside is the loss of the bonus itself, not a smaller upgrade.

Where Book of Dizzy fits in supplier content

Expanding reels and symbol-upgrade mechanics sit in a crowded part of the slot catalog, and new releases from smaller studios usually reach players through operator partnerships. Earlier Gamingo coverage shows how that distribution works, from NetBet Italy's partnership with ELK Studios to White Hat Studios' Pennsylvania launch with Caesars and PopOK Gaming's tie-up with BC.Game.

DEGEN's approach is to compete on mechanics rather than theme alone. Book of Dizzy pairs a familiar book-style bonus with a variable grid and a player-controlled risk step, and it follows Loot Box Legends, which the studio built around switchable RPG and FPS modes.

Frequently asked questions

What is Book of Dizzy?

Book of Dizzy is a video slot from DEGEN Studios. It opens on a 5x3 grid with 10 paylines, and the reels can expand at random to 5x4 or 5x5. Its main features are Expanding Reels, a random Expanding Symbol, a free spins bonus with three modes and a Pre-Bonus Gamble.

How many paylines does Book of Dizzy have?

The slot has 10 paylines on its starting 5x3 grid. When the reels expand to 5x4 the count rises to 15 paylines, and on a full 5x5 grid it reaches 20 paylines. The number of active paylines therefore depends on how far the reels have grown on a given spin.

How do you trigger the free spins in Book of Dizzy?

Free spins are triggered with Wild Scatters. Landing 3 Wild Scatters starts the Open The Book mode, 4 start Turn The Page, and 5 start Master Spellbook. A higher scatter count therefore leads to a different version of the bonus round.

What is the Pre-Bonus Gamble in Book of Dizzy?

The Pre-Bonus Gamble is an optional step before free spins begin. Players can try to increase reel height, remove low-paying symbols or upgrade the Expanding Symbol. Each enhancement is gambled separately, and if an attempt fails, the player forfeits the bonus round.

How does the Expanding Symbol work in Book of Dizzy?

A randomly chosen Expanding Symbol expands to cover entire reels. It still pays when reels without the symbol break up the winning sequence. It can also activate on the same spin as the Expanding Reels feature, so a single spin can combine both.
