The series of games featuring these mad feathered friends from ELK Studios has long been a hallmark of the provider. We’ve seen them as pirates, explored jungles, and even donned cowboy hats. But this time, the developers have decided that Earth simply isn’t enough. Get ready to play Pirots 4, because our old mates are off to conquer the depths of space!

Key Features of the Pirots 4 Slot
Before diving into the intergalactic hunt for profit, it’s worth checking the “onboard log” of this ship. The slot retains its signature high volatility, meaning the game might test your patience for ages before unleashing a string of big prizes.
- Provider: ELK Studios.
- Mechanics: the provider’s unique CollectR™ system.
- Grid: 6×6 playing field with the potential to expand to 8×8.
- Max Win: x10,000 your stake.
- RTP: around 94%.
- Volatility: high.
In the Pirots 4 slot, everything revolves around collecting colourful gems — one colour for each bird. The higher the gem’s level (there are 7 in total), the bigger the payout. If you’re not yet familiar with how the birds scamper across the grid “devouring” symbols of their colour, I strongly recommend starting with the Pirots 4 demo so you don’t burn through your bankroll just learning the rules.
Symbols, Locations and the CollectR™ Mechanic

Unlike classic slots, Pirots4 has no paylines. Four birds are always present on the grid (red, purple, green, and blue). They move vertically and horizontally, gobbling up symbols that match their colour.
- Low Symbols: basic-level elements.
- High Symbols: elements upgraded to level 7 using special rocket symbols.
- Wilds: substitute for any gem at its current level.
- Scatters (Bonus): land three of these and you’re straight into the bonus game.
The most thrilling part of the Pirots 4 mechanic is the unpredictability of the birds’ paths. When one hits a rocket or another modifier, it can zoom across the entire grid, triggering a chain reaction of collections.
Locations: Lost in Space, Frozen Fury, Inferno

One of the standout features of the Pirots 4 slot is the dynamic change of environment. Depending on the game phase and the activation of bonus features, players travel between three distinct cosmic sectors.
- Lost in Space — the base cosmic location and your entry point into the game. It offers the classic game pace along with the Alien Invasion mechanic, where a space adversary interferes in the round and boosts winning potential.
- Frozen Fury — an icy zone with a more cautious and tactical rhythm. The key mechanic revolves around the Yeti, who freezes the birds and thereby increases the multiplier.
- Inferno — the final fiery location with the most aggressive pace. Here, fire minions appear, setting birds ablaze and triggering chain reactions with rapid movement and the generation of symbols or coins.
Special Symbols: Bombs, Black Hole, Spacecorn

ELK Studios are renowned for turning slots into something akin to a video game. When you play Pirots4, the Collection Bar at the top of the screen becomes your best friend. By collecting gems, you fill the bar, which then drops additional modifiers onto the grid:
- Corner Bombs. When a bird collects a bomb, it detonates only after all possible collections on the current grid are finished. The explosion clears nearby symbols (except special ones), refreshes the grid, and expands it to the maximum 8×8 size. This opens up new space for manoeuvres.
- Black Hole. One of the most spectacular features. It sucks in gems and triggers an avalanche of new symbols falling in. The real magic lies in how the black hole repositions the birds into often far more favourable spots, letting the collection chain continue exactly where it looked like it had hit a dead end.
- Upgrade. These rocket symbols increase gem values. A silver rocket upgrades gems of the same colour as the bird that collected it, while a golden rocket boosts the level of every gem on the grid at once.
- Coins. Your route to instant profit. Coins carry stake multipliers. If a bird reaches the rare Max Win coin — you instantly bag the top prize of x10,000.
- Transform. Converts a group of gems surrounding the bird into symbols matching the bird’s colour, or into special symbols, to help fill the progress bar.
- Spacecorn. When a bird eats popcorn, it fills empty cells on the grid, allowing the feathered crew to hop over gaps to reach the symbols they need.
With such a rich array of mechanics, every spin in the Pirots 4 slot feels wildly unpredictable. You never know whether a routine collection of a blue gem will snowball into a chain of explosions and teleports that ultimately triggers the bonus round. It’s precisely this controlled chaos that players adore about the entire Pirots series.
Bonus and Super Bonus Games

The bonus game in Pirots 4 is a sophisticated mathematical progression. The round triggers when the birds collect three bonus symbols — golden skulls.
In the standard bonus mode, the cumulative effect becomes the key factor. Unlike the base game, where counters reset after every unsuccessful collection, the following rules apply here:
- Persistent Grid Growth. If a bomb detonation expands the playing field from the base 6×6 to 7×7 or the maximum 8×8, that size is locked in for the remainder of the feature.
- Symbol Level Carryover. Every gem upgrade (via Upgrade symbols) becomes permanent. If the birds collectively push the blue crystal level to 5, every subsequent free drop will feature blue gems dropping at that exact value.
- Accelerated Modifier Bar. The progress bar at the top of the screen fills much faster in the bonus, thanks to birds frequently landing helpful symbols such as popcorn or black holes.
If the bonus is activated with a Super symbol (the three-eyed skull), the game shifts into Super Bonus mode. From an expert perspective, this is the slot’s “Overdrive” state. The main differences that define the Super Bonus potential are:
- Instant 8×8 Grid. No need to waste early spins expanding the field with bombs — the game launches straight onto the maximum 8×8 grid.
- Enhanced Special Symbol Generation. In Super Bonus, the algorithm drops Coins and Upgrade All symbols far more frequently.
- Modifier Synergy. Black holes and teleports work in tandem much more often. Birds almost never get stuck, turning each free drop into a prolonged sequence of 20–30 cascading collections.
To illustrate the payout difference: average wins in the regular bonus tend to hover between x50–x150, whereas Super Bonus is built for runs of x500 and beyond, all the way up to the x10,000 cap. This is precisely why experienced players frequently turn to the X-iter™ feature.
Pirots 4 Demo: Why You Should Start with the Free Version
Many experts recommend the same thing: before depositing any money, open the Pirots 4 demo. Why is this especially important here?
- Complexity of the mechanics. You need to grasp how the birds interact and how black holes behave.
- X-iter™ feature. The demo lets you test-purchase every bonus mode for free, so you can see which one tends to deliver the best return.
You get exactly the same mathematical model as in the real-money version — just without risking actual cash.
Who Will Enjoy This Slot?
If you’re tired of bland fruit slots — play Pirots 4. The game is a perfect fit for:
- Fans of intricate bonus mechanics
- Players willing to endure long “dry” spells in exchange for one explosive bonus
- Those who appreciate high-quality graphics and humour in the design
And of course, it will appeal to fans of the rest of the Pirots series — this is a brilliant next chapter in the adventures of the pirate parrots.
Final Verdict
The fourth instalment in the franchise proves that ELK Studios still has plenty of fresh ideas. The cosmic theme refreshes the series, while the refined black hole and teleport mechanics make the gameplay even more dynamic. My verdict: one of the standout releases of the year. That said, given its punishing volatility, my main piece of advice is simple — start with the Pirots 4 demo, get a real feel for the game’s rhythm, and only then set off in pursuit of genuine cosmic treasures.
