Mongol Treasures Slot Overview
Strip away the scenery and this is a game about horses. Five breeds carry the paytable, each painted into its own little backdrop, a black stallion in grey mountain mist, a white one against snow, a chestnut standing in summer grass, and a Mongolian warrior sits above them all at 500x for five. The idea worth loading it for lives in the free games, where a single symbol gets singled out and grows tall enough to fill an entire reel.
Everything else is 2015 in a good mood. Ten adjustable lines on a 5x3 grid, 96.05% RTP, high volatility, stakes running from 0.10 to 45. The Bonus Pop button on the left rail has aged the best of anything here, because it does not simply sell you the bonus, it lets you nominate which symbol does the expanding.
Theme & Design
The whole game sits inside one long golden hour. Ochre dunes roll along both edges of the grid, a few horses graze in the left distance, and a felt ger with a spear planted beside it holds the right side, all under a sky that never stops being sunset. The reels are parchment panels set in a carved wooden frame with small gold corner filigree, which suits the steppe setting far better than the glossy coloured card royals do. Green J, red A, a pink 10: they look pasted in from a different game.
The character art is where the money went. The warrior has long loose hair, a full beard and a tattooed shoulder; the woman wears a coral robe and a pearl headdress, smiling out of a red-bordered frame with flowers behind her. Wins are presented nicely too, with everything outside the paying line draining to sepia while the winning symbols stay lit and outlined in gold. The sound is ambience rather than a score, and the art shows its decade in places, but the mood holds.

Features & How They Work
Free Games with Expanding Symbols
Three or more scatters anywhere on the reels award 10 free games. Before the first of them spins, one symbol is drawn at random and marked as the expanding symbol for the round. Whenever enough copies of it land to complete a winning combination, each one stretches vertically to cover all three positions on its reel.
Two rules make this bigger than it sounds. Position does not matter, only the count, so those symbols never need to sit next to each other for the expansion to fire. And expanded symbols pay on enabled lines from non-adjacent positions, which suspends the usual left-to-right adjacency requirement for the length of the round. The wild is locked out of all this, since it cannot substitute for the chosen symbol. Scatters landing during the round retrigger it, and free games run at the same bet and line count as the spin that started them.
Bonus Pop
Bonus Pop buys the free games outright, and it hands over the one decision the round normally makes for you: which symbol expands. Nominate the warrior and every expansion pays heavily but turns up rarely. Nominate a royal and expansions come often for small money. The price moves with your stake and with the option picked, landing around 69x total bet at the entry-level choice. The purchase plays out as one base spin that resolves into three scatters, and anything won through it cannot be pushed into the Risk Game. Casinos decide whether the button appears at all.
Wild and Scatter
The Mongolian woman is the wild and pays 200x for five of her own, level with the white horse at the top of the animal symbols. She covers every symbol except the scatter. The scatter counts from any position rather than along a line, and it carries small pays of its own on top of starting the bonus.
Risk Game
Any base win can be pushed into the card gamble, where beating the dealer's card doubles the amount, up to ten times in a row. Jackpot money and Bonus Pop money are both excluded. It is the same double-or-nothing ladder Endorphina drops into nearly everything (some players hit it after every win, most never touch it), and it is still the quickest way to end a session early.
Mystery Jackpots
Three progressive tiers sit above the game, Minor, Major and Grand, awarded at random rather than through anything you can chase. They depend on the operator running the pool, and that money cannot be gambled either.

How Mongol Treasures Plays
Ten lines on a five-reel grid sets the tempo, and the tempo is patient. Base spins mostly hand back royals worth a fraction of the stake, the balance drifts down in small steps, and there is nothing to collect or fill along the way. You are hunting three scatters. That is the base game, all of it.
What is unusual is that the bonus holds a second lottery inside it. Ten free games with the warrior chosen plays nothing like ten free games with the 10s chosen, and you learn which one you got before the first spin even resolves. The tension sits right there, and it is also why the round can land flat: a low-value pick with an unhelpful spread of symbols burns through all ten spins for pocket change. Bonus Pop deletes that coin flip, which probably explains why it is the button most players reach for.
The 5,000x ceiling is a long way from any of this. It wants the top symbol expanded across most of the grid at once, and high volatility means the road there runs through plenty of nothing.
Pros & Cons
Pros
- Bonus Pop lets you choose which symbol expands instead of just buying the round
- Expanding symbols pay from non-adjacent reels, which breaks the normal line rules in your favour
- Warm steppe artwork with five distinct horse portraits, each given its own backdrop
Cons
- The base game is empty between scatter hits: 10 lines, no multipliers, nothing to build up
- The wild cannot cover for the expanding symbol, so an unlucky random pick wastes the whole round
- Card royals clash badly with the hand-painted symbols beside them
Is Mongol Treasures Worth Playing?
Endorphina had a good idea in 2015 and mostly stayed out of its way. Picking your own expanding symbol rather than accepting whatever the game deals is a piece of agency plenty of newer slots still do not give you, and the non-adjacent payment rule gives the free games more reach than a 10-line slot usually gets.
The frame around it is a decade old and looks it. No ante bet, no multiplier ladder, no second feature to break up the base game. For my money the artwork and the Bonus Pop decision carry this further than the maths does. The 2022 sequel, Archery Competition, threw out the expanding symbols for a target-shooting bonus, so it is a separate game rather than a continuation of this one.
