How the Game Plays

Mystery of Eldorado by Endorphina takes players deep into the South American rainforest on a quest for the fabled city of gold. The visual design features lush jungle backdrops and ancient stone temples, setting a professional tone for its 5x3 grid. Winning combinations are formed by landing matching symbols across 10 fixed paylines, starting from the leftmost reel. High-value symbols include the golden temple and the intrepid explorers, while colorful gemstones represent the lower tier of payouts. The central symbol is the treasure map, which pulls double duty as both the Wild and the Scatter, substituting for other icons to complete wins.

Free Spins Explained

Landing three or more Map symbols triggers the bonus round, awarding 10 free spins. Before the round begins, a random symbol is chosen to act as a special expanding symbol. If enough of these symbols land to form a win, they expand to cover the entire reel, paying out across all active lines regardless of whether they are adjacent. This mechanic is highly reminiscent of classic "Book of" slots and provides the game's highest payout potential. The feature can also be retriggered by landing additional scatters during the free spins.

Bonus Pop and Risk Game Explained

For those who prefer to bypass the base game, the Bonus Pop feature allows direct entry into the free spins for a fixed cost. Additionally, Mystery of Eldorado includes a classic Endorphina Risk Game. After any successful spin, players can choose to gamble their winnings in a card-based mini-game. You are presented with one face-up dealer card and four face-down cards; picking a card higher than the dealer's doubles your win, with the option to repeat the process up to ten times.
