Overview
Mystery of Eldorado is a jungle treasure hunt from Endorphina, sat on a classic 5x3 grid with 10 paylines. Nothing fancy about the layout, but the theme is the usual lost-city-of-gold stuff: Amazonian vibes, a ruggedly handsome treasure hunter, a scientist lady, and a grumpy lost soul guarding the loot.
Game Details and Betting
RTP sits at 96.05%, which is bang on average, and volatility is high. So yeah, expect some patches where the reels do nothing, mate. Bets run from 0.10 up to 45 a spin, so it suits small budgets and folks happy to push it a bit harder.
Top symbol win is 500x your stake for five pyramids, which isn't life-changing numbers. For a high-vol slot I'd honestly hope for a bigger ceiling, but the free games with the expanding symbol is really where the proper pay is meant to come from.
Symbols and Paytable
Four main symbols do the heavy lifting here. The pyramid is your top dog at 500x for five-of-a-kind. The treasure hunter man pays 200x for five, and the girl scientist chips in 75x for five. Decent enough spread, nothing mad.
The Map is the star though. It's both Scatter and Wild rolled into one, so it subs in for regulars AND triggers the free games. Five Maps landing also pays 200x the base bet. Handy little symbol to have on your side.

Bonus Features
Land 3 or more Map scatters and you get 10 Free Spins. At the start of the feature, the game picks one random symbol to be the special expanding one. When that symbol lands and there's a win on the cards, it stretches out to cover 3 positions on its reel. Pays on non-adjacent spots too, which is nice.
Free games can re-trigger during the feature, so you can push your luck further. There's also the classic Risk Game where you can gamble any win to double it, and a Bonus Pop option, though that one isn't available everywhere depending on the casino.
