Mystery of Eldorado Slot Symbols

Mystery of Eldorado offers a diverse range of symbols that players will notice as soon as they start spinning the reels. There are almost 10 basic symbols in total, divided into two distinct categories based on their payouts. The low-paying symbols consist of three gems and two idols. Each gem has the same reward ratio, offering a payout of x100 the line bet for a combination of five identical symbols. The idols share a paytable, and players can earn a payout of x150 the line bet by aligning five of the same idol symbol.

On the other hand, the high-paying symbols in Mystery of Eldorado offer more diversity. The Servant and the Assistant share a paytable, with both symbols offering a x750 payout for a sequence of five identical symbols. The Archaeologist symbol is even more lucrative, with a payout of x2,000 for spinning five of this symbol on the same payline. Finally, the Temple symbol is the highest paying symbol in the game, with a payout of x5,000 the line bet for a combination of five Temple symbols.

The game also features a special symbol, the Map, which acts as both a Wild and Scatter symbol. The Map symbol can substitute for any of the basic symbols on the reels and trigger free spins. Additionally, it has its own paytable, with a payout of x2,000 the line bet for spinning five Map symbols.

Mystery of Eldorado Slot Bonus Features

Free Spins Feature

The Free Spins feature in the Mystery of Eldorado slot game is triggered when three or more Scatter symbols (represented by a golden pyramid) appear anywhere on the reels. Players are awarded 10 free spins, and before the free spins begin, a special expanding symbol is chosen at random. If the chosen expanding symbol appears during the free spins, it will expand to cover the entire reel, potentially leading to bigger payouts.

If players land three or more Scatter symbols during the free spins, they will be awarded an additional 10 free spins. This can be re-triggered indefinitely, offering players the chance to accumulate big wins.

Gamble Feature

The Gamble feature in the Mystery of Eldorado slot game allows players to double their winnings by correctly guessing the color or suit of a face-down card. After a winning spin, players can choose to gamble their winnings by selecting either the red or black color or one of the four suits (hearts, diamonds, clubs, or spades) of the face-down card.

If players correctly guess the color of the card, their winnings are doubled. If they correctly guess the suit, their winnings are quadrupled. However, if players guess incorrectly, they will lose their winnings from that spin.

It’s important to note that the Gamble feature is entirely optional, and players can choose to collect their winnings without gambling if they prefer.


The Mystery of Eldorado slot game by Endorphina is a well-designed and exciting online slot game with impressive graphics and sounds. With diverse symbols, a Free Spins feature triggered by Scatter symbols, and a Gamble feature for doubling winnings, players are sure to enjoy an engaging and potentially rewarding gaming experience.
