Deep in the jungle, a lost civilisation left behind gold beyond imagination. Treasures of Aztec on 399 brings that world to life with cascading reels, expanding wilds, and free spin rounds that can multiply your winnings up to 5000x. It's one of the most played slots on the platform — and once you try it, you'll understand why.
Treasures of Aztec is a high-volatility slot built around the mythology and imagery of the ancient Aztec civilisation. The game runs on a 6×5 grid with a cascading reel mechanic — meaning every winning combination disappears and new symbols fall into place, giving you multiple chances to win from a single spin. It's the kind of mechanic that can turn a modest bet into something much more significant if the right symbols keep landing.
On 399, the game is available in both demo and real-money modes. The demo lets you get familiar with the cascading system and the free spin trigger before you commit any real funds. Once you're comfortable, switching to real-money mode is straightforward and your first deposit on 399 qualifies for the welcome bonus.
The visual design is genuinely impressive — rich jungle backgrounds, detailed Aztec temple symbols, and smooth animations that don't slow down even on mid-range Android phones. 399 has optimised the game for mobile play, so the experience on a phone is just as good as on a desktop browser.
The game packs in several mechanics that work together to create big win potential. Here's what you need to know before you spin.
Winning symbols vanish and new ones fall from above. Each cascade in a single spin can trigger another win, creating chain reactions that build up quickly. On 399, a single spin can cascade five or six times if the symbols cooperate.
Each consecutive cascade within a single spin increases the multiplier. Start at 1x, hit a second cascade and it jumps to 2x, then 3x, and so on. During the free spin round on 399, this multiplier doesn't reset between spins — it keeps climbing.
Land four or more scatter symbols to trigger the free spin round. You start with eight free spins and the cascade multiplier carries over between spins. This is where the 5000x maximum win on 399 becomes genuinely reachable.
The golden jaguar acts as the wild symbol and expands to cover an entire reel when it lands. An expanded wild on a reel loaded with high-value symbols can produce some of the biggest single-spin wins available on 399.
The sun stone scatter pays anywhere on the grid regardless of position. Four scatters trigger free spins, five give you ten spins, and six award twelve. Retriggers are possible during the bonus round on 399, extending your session further.
Don't want to wait for the scatter to land naturally? 399 offers a bonus buy option that lets you purchase direct access to the free spin round for a fixed multiple of your bet. It's a faster route to the high-multiplier bonus on 399.
Treasures of Aztec uses a cluster pays system — you need a group of five or more matching symbols connected horizontally or vertically to form a win. Here's a breakdown of the main symbols and their approximate payout values for a cluster of five on 399.
Unlike traditional payline slots, Treasures of Aztec on 399 pays for clusters of five or more matching symbols that are connected horizontally or vertically anywhere on the 6×5 grid. Larger clusters pay more — a cluster of fifteen or more of the golden idol symbol combined with a high cascade multiplier is how the biggest wins on 399 happen.
Treasures of Aztec carries a published RTP of 96.7%, which is above average for the slot category. In practical terms, this means the game returns a higher proportion of bets over time compared to many other slots available on 399 and elsewhere.
The volatility is high, which is the trade-off for that 5000x maximum win potential. High volatility means wins come less frequently but tend to be larger when they do land. If you're the kind of player who prefers steady small wins, this game will test your patience. But if you're comfortable with longer dry spells in exchange for the chance at a genuinely big payout, Treasures of Aztec on 399 is built for you.
The bonus buy feature on 399 is worth considering if you want to skip straight to the free spin round where the real multiplier action happens. It costs more upfront but removes the waiting time for the scatter to land naturally.
