Mystery of Eldorado is a video slot experience created by the provider Endorphina. In this Mystery of Eldorado slot review you’ll learn about its core features (including RTP, max win, and volatility), the bonus mechanics, and what helps the game stand out — along with the areas where it may fall short.
Mystery of Eldorado is played on a 5 reel layout with up to 10 paylines/ways. The game includes a variety of features such as Expanding Symbols, Gamble, Retrigger, Scatter Pays, Special Symbol, Wilds, and more. There’s also a dedicated free spins bonus round, which is typically where the game’s biggest win potential comes into play.
The standard RTP (Return to Player) for Mystery of Eldorado slot is 96% (Could be lower on some sites). This payback is good and considered to be about average for an online slot. Theoretically, this means that for every €100 put into the game, the expected payout would be €96. However, the RTP is calculated on millions of spins, which means that the output for each spin is always random.
