Bonus Features

Wild Symbol and Scatter Symbol

The Mystery of Eldorado slot game introduces a versatile symbol, the Map of Eldorado, which serves dual roles as both the Wild and Scatter symbol. In its Wild capacity, it adeptly substitutes for any symbol to complete winning combinations. However, it’s important to note that during the Free Spins feature, it cannot substitute for the special expanding symbol.

In its Scatter role, the Map of Eldorado symbol holds the key to unlocking the Free Spins feature. Land three or more of these symbols anywhere on the reels, and the adventure takes an exciting turn.

Free Spins

Triggered by landing a minimum of three Scatter symbols, the Free Spins feature awards players with 10 free spins accompanied by a special expanding symbol. Before the free spins commence, a symbol is randomly chosen to become the special expanding symbol for the entire duration of the round. Should there be enough of these special symbols to form a winning combination, the expanding symbol activates. As it unfolds, the symbol can expand to cover three positions on the reel where it lands during the free spins, even in non-adjacent positions. This captivating feature maintains the same bet and line settings as the base game and can be retriggered within the ongoing Free Spins feature.

Gamble Feature

A familiar and enticing element, the Gamble feature offers players the chance to double their winnings. Upon opting for the gamble feature, a new game unfolds with five cards, one of which is face-up. The objective is to choose a card and hope it surpasses the face-up card, doubling your winnings. Successful guesses grant the option to collect the doubled winnings or continue the doubling adventure. However, an incorrect guess results in losing everything and returning to the base game. The Gamble feature adds an extra layer of excitement and risk for those seeking an adrenaline-fueled gaming experience.


Mystery of Eldorado delivers an immersive and visually stunning slot experience. Set against the backdrop of a South American adventure, the game’s symbols and features, including the Map of Eldorado and Free Spins with expanding symbols, add excitement to the quest for the Golden City. With captivating graphics and thrilling bonuses, Mystery of Eldorado promises both entertainment and the potential for rewarding exploration in the heart of the jungle.
