When you open the demo version, you’ll notice that the game takes place in an Amazonian setting surrounded by ancient temples. There are some beautiful details and animations in the game that are triggered when wins are hit, helping to provide a more immersive experience. The action takes place over 5 reels and 3 rows and has 10 selectable paylines. In the game controls, which are underneath the reels, you can place bets from between 1p and £100 per spin. This is a decent betting variance that should appeal to most gamers, whether high or low rollers.

The Rules and Features of Mystery of Eldorado

The rules of Mystery of Eldorado online are simple and the game’s mechanics are very similar to other Endorphina titles, for instance Luxury Life or Lucky Dice 3. All you need to do is land the symbols in the correct combinations over your selected paylines and you can win. To make things more exciting, there are a number of special features to this game. The Free Spins game is triggered once you hit 3 Scatter symbols across the reels. This combination will also bring a multiplier of up to 200x your bet. In the free spins round, the game also picks one symbol to become an expanding symbol that stays active for the duration of the round.

Like most Endorphina games, there is a Gamble round that is available every time you win and can be opened by selecting ‘Take Risk’ below the reel. In this round, 5 cards appear, with one card face up and the rest face-down. You will need to select one face-down card in the hopes that it is higher in value than the card shown. If it is, your wins are doubled but if it’s not, you lose your winnings. Unfortunately this is not one of the feature buy slots gaining popularity these days.

There are nine different symbols represented on the board. These are the Eldorado Map which is both the Wild and Scatter, two archaeologists, a treasure wielding assistant, some golden artifacts and the city of Eldorado itself, which can bring a multiplier of 50,000 that can help to bring you the max Jackpot prize of £500,000. The inclusion of both the Wild and Scatter feature as the same symbol means that there are plenty of opportunities to win. The simplicity of the paylines in addition to the numerous features and captivating graphics makes this game well worth the time and is undoubtedly one of Endorphina’s better offerings.
