Avalanche™ Wins and Expanding Reels

Gonzo Goes Mental builds its gameplay around the Avalanche™ feature, where winning symbols disappear and new symbols fall into their places, creating opportunities for consecutive wins within a single spin. Each Avalanche increases the main-game multiplier by +1, starting at x1 and reaching up to x5.

Every spin begins on a 5×4 grid, but the appearance of partially visible Colossal Symbols can push the reels higher, expanding the playing area to as many as eight rows. These oversized symbols can occupy 2×2, 3×3 or 4×4 positions, adding another dimension to the game's growing number of winning ways.

Colossal Symbols and Wild Features

Colossal Symbols represent groups of matching symbols on the reels, with larger versions counting as multiple symbols when evaluating winning combinations. Their presence can dramatically change the layout of a spin, particularly when combined with the Avalanche™ mechanic.

Two types of Wilds add further possibilities. Regular Wilds substitute for playing symbols, while Calamity Wilds introduce an additional surprise: when involved in a win, they can randomly place between two and five regular Wild symbols onto the reels before the next Avalanche.

Fire Frames and Growing Winning Ways

Winning combinations involving Wild or Calamity Wild symbols can create Fire Frames, transforming the way symbols behave in the affected positions. Regular symbols inside these frames split into two, while Colossal Symbols can split into multiple smaller symbols, increasing the available winning ways.

The interaction between Fire Frames, Wilds and Avalanches gives each spin the potential to develop beyond its original layout, with new combinations emerging as symbols disappear and the grid changes.

Delusional, Mad and Mental Spins

Collecting Bonus symbols during a single spin unlocks the game's Free Spins feature. Three Bonus symbols award 5 Free Spins, six award 8 and nine award 11, introducing three increasingly intense bonus levels: Delusional Spins, Mad Spins and Mental Spins.

During Free Spins, the Avalanche™ multiplier increases by +2 after each cascade and can reach an extraordinary x666. Expanded reels also remain in place throughout the bonus, rather than returning to their original height after each spin.

Additional Bonus symbols contribute towards upgrading the feature from Delusional to Mad and ultimately Mental Spins, with each upgrade adding three more Free Spins.

Special Features and Multiplier Enhancements

Free Spins can unlock Special Features that make Gonzo's nightmare even more unpredictable. Every three collected Bonus symbols unlock a Special Feature spot, which can reveal additional effects or remain empty.

Possible rewards include extra or locked Fire Frames, Calamity Wilds and multiplier enhancements. The Broken Wheel can increase the multiplier to values as high as x666, while the Locked Wheel prevents it from resetting for the remainder of Free Spins.

These effects introduce new ways for the reels and multipliers to evolve as the bonus progresses.

Elevate Feature

Gonzo Goes Mental also includes the Elevate Feature, offering several ways to influence gameplay or access bonus rounds directly.

Bonus Hunt increases the chance of triggering Free Spins, while Calamity Explosion guarantees a winning combination containing a Calamity Wild. Players can also choose direct entry into Delusional Spins, Mad Spins or Mental Spins, with each option carrying a different cost based on the current bet.

Gonzo's Wildest Adventure Yet

Gonzo Goes Mental transforms the familiar El Dorado expedition into a surreal jungle nightmare, where ancient stone faces, unpredictable transformations and increasingly powerful multipliers keep the adventure moving. With Expanding Reels, Colossal Symbols and three escalating Free Spins levels, NetEnt gives its famous explorer a darker and more chaotic journey than ever before.
