Mystery of Eldorado Slot Review

Released June 2019

The Mystery of Eldorado game can be found at casinos offering Endorphina software. Endorphina are one of the newer casino software providers on the market but they have managed to gain distribution with some of the largest casino networks currently active within the market. As a standard Endorphina do publish the RTP/House Edge information for their slots games within the game help file or paytables. As a software provider not licensed in the UK, and as such not required to publish this information, this is a significantly player friendly practice. As such we can state that the Mystery of Eldorado House Edge is 4.00%.

Mystery of Eldorado is a 5 reel slots game and each reel is 3 symbols high. The game uses 10 paylines, playing from left to right.

Special Symbols

Wild/Scatter – The game’s Scatter symbol is the “Eldorado Scroll”. You need 3 or more of them anywhere on the reels at once to trigger the Free Spins feature. It also happens to be the game’s Wild symbol, meaning it will substitute for all paying symbols, along with paying out regardless of paylines.

Valuable Symbol – The slot’s most valuable symbol is the “Golden Pyramid”.

Bonus Features

Free Spins – Once you have triggered the Free Spins by landing 3 or more of the Scatter symbols you will be awarded 10 Free Spins and a Special Expanding symbol. Before the Free Spins begin a symbol is chosen at random to become the Special Expanding Symbol. When a win is formed with that symbol, all of them will expand to fill the reel that they appear on. Expanded Symbols will pay out after the standard symbol payout.

Take Risk – Whilst you might not necessarily class this as a bonus feature, it does play a significant role in the gaming experience. With every win you get the chance to try and double your win by trying your luck in a game of “Play Your Cards Right” with the game’s dealer. If you can flip over a card that is higher than the one the dealer is showing you will double your win. Flip a card that is lower than the dealer’s and you lose the lot. This round continues until you either choose to stop gambling or you lose out to the dealer. In the result of a tie, no one wins.


You cannot help but love how good Mystery of Eldorado looks. The character symbols are well-drawn, full of detail and colour, as are the other symbols. Of course, looking good is not enough for a good score, something that the Wilds and the Free Spins with the Special Expanding symbol just about make up for. A bonus feature wouldn’t go amiss, and neither would the inclusion of some random features to help break up the monotony. The house edge is nothing for us to get excited about either, which means that this is decent game that falls flat just at the end.
