4 Masks of Inca: Slot Overview
One thing you can say about parts of the Games Global studio family is that they really have a thing for masks. Provider Foxium adds another to the collection with 4 Masks of Inca. The name is partly spot on and partly a touch deceptive. On the one hand, 4 Masks of Inca is absolutely a South American-themed slot, complete with the sort of sights and sounds you’d expect from a game set in that region. On the other hand, while the title may bring 9 Masks of Fire to mind, the two are actually miles apart in how they play and feel—aside from both featuring masks, there’s not much overlap.
A hallmark of Foxium releases is the studio’s careful presentation and knack for building an attractive scene. 4 Masks of Inca may not be the most jaw-dropping Inca slot ever made, but it opens with a nicely atmospheric intro featuring a stern ruler on his throne before the action begins. From there, Foxium uses a currently popular top-down perspective and fills the setting with appealing Incan stone textures, plenty of polished animations, and a clean set of UI/game elements. The music matches the tone too—dark and brooding rather than showy, but with a refined quality that suits the theme.

Sitting above the temple—palace, or whatever the exact location is meant to be—is the main grid. It uses 5 reels with 3 rows, and play runs across 20 paylines. 4 Masks of Inca is a medium volatile slot and comes in four RTP configurations, topping out at 96.22%. Bets range from 20 p/c to $/€12 per spin, and players can choose whether to enable the Boost. Turning Boost on increases the stake by 50% in exchange for better chances of triggering free spins, Inca Battles, and Wild Puma Awards.
Standard payouts come from landing at least 3 matching symbols, starting from reel 1. The lower-value symbols are Inca-styled 9-A royals, paying 1.25 to 3.75 times the bet for a 5 OAK line win, while the premium symbols are four detailed mask icons. The masks return 7.5 to 10 times the bet for a 5-of-a-kind. Puma wilds can appear on any reel and substitute for any regular paying symbol. Wilds arrive with a multiplier of up to x5, and if a win includes multiple wilds, their multipliers are multiplied together. A 5 wild line pays 25 times the bet.
4 Masks of Inca: Slot Features

Wilds also contribute to a feature called Wild Puma Collect, and players should note the free spins round, the Inca Battle feature, and the bonus buy option.
Inca Battle
In the base game there are 4 tokens in red, purple, blue, and green. Tokens can land on high-paying symbols and are collected into their matching meter when they appear. Once 3 tokens of the same colour have been collected, an Inca Battle begins. When triggered, players receive 5 spins, and each mask is assigned a value of 10x to 10,000x the bet. Across those 5 spins, whichever mask lands the most times awards its prize.
Wild Puma Collect
Wilds that land during the base game are collected by the Wild Puma Collect meter. This may result in a random activation where the Wild Puma Award hands out a prize worth 10x to 50x the bet.
Free Spins
Hitting 3 scatter symbols in the base game on reels 1, 3, and 5 triggers the free spins feature. To begin, 3 free spins are granted. However, whenever a wild symbol lands, it becomes sticky on the reels with an x1 multiplier for the rest of the feature and resets the spin count. On every spin, the multiplier on one random wild is increased by +1. As in the base game, if more than one wild is involved in a win, the multipliers are multiplied together.
Buy Free Spins
After the free spins round has been triggered once naturally, players can then purchase it going forward. The price is 60x the bet.

4 Masks of Inca: Slot Verdict
Anyone familiar with the Gameburger Studios success 9 Masks of Fire will quickly see that 4 Masks of Inca isn’t trying to imitate it in the slightest. Similar titles aside, this is its own game. Another plus is that it doesn’t feel like a carbon copy of other slots set in this region either, even though Inca/Aztec themes are everywhere. Yes, some artistic elements will naturally feel familiar—there’s only so far you can push originality with this subject—but Foxium has still delivered strong visuals, ensuring 4 Masks of Inca is packed with attractive details, both static and animated. The audio side holds up nicely too.
The gameplay is solid as well. While the medium volatility may not be as intense as some players prefer, the features still bring plenty of swing. Inca Battle is perhaps the steadier of the bunch, since it’s essentially a contest to see which mask appears most often during the set number of spins and then pays its assigned value—ideally the 10,000x one, or close to it. Free spins, meanwhile, felt like it could go either way in a big way. Sticky wild multipliers combined with a rising multiplier element made it feel very unpredictable, in a similar spirit to Relax Gaming’s Top Dawg$ or even Dead or Alive 2 if you stretch the comparison. It may not deliver the same white-knuckle tension as NetEnt’s classic, but with potential wins up to 20,000x the bet, there’s definitely room for something special to happen.
All told, 4 Masks of Inca may not be Foxium’s headline release, but it’s a well-crafted package regardless. With strong presentation, fitting audio, and features that run smoothly, it shows there’s still plenty of Inca-inspired territory left for slot developers to explore.
