Feature Testing

Swedish studio that iterates rather than innovates wildly, perfecting systems over time. One drop with quadruple the normal chance of triggering the bonus game. Triggered when you clear the entire grid during the Spacecorn feature.

Those who enjoy gem themes may especially appreciate this slot’s unique twist. Pirots introduces players to a cast of feathered pirates. The game is optimized for both desktop and mobile play, providing seamless adventure wherever you are. The first thing that grabs your attention is the beautifully crafted pirate theme. From the cannonball sound effects to the vivid graphics depicting treasure maps and pirate ships, every detail immerses you in this adventurous world.

Step 8: Explore X-iter Feature Buys

Unlock the Free Drops feature to activate special modifiers that can supercharge your winning potential. ELK Studios has also integrated their signature X-iter mode, allowing players to purchase direct access to bonus rounds for those who prefer instant action. Free Drops begin when three Bonus symbols land, granting 8–12 spins with a permanently expanded 8×8 grid. During this round, all Symbol Collection effects are amplified, and the Lost in Space feature can trigger more frequently. The Super Bonus variant—accessed via the X-iter™ buy feature or rare triggers—doubles all cash prizes and guarantees max grid expansion.

This removal creates cascades while leaving behind Wilds, Multipliers, or instant credits. The unpredictability of alien targeting adds delightful chaos, with strategic depth emerging from how the invasions disrupt symbol patterns to create new winning paths. It’s a perfect thematic fit, casting players as defenders reclaiming treasure from cosmic thieves. Landing coins or bridge symbols resets the counter back to three.

Step 2: Understand the CollectR Mechanic

The game maintains 94.0% RTP across all modes including X-iter. Stakes cannot change during active rounds, and malfunctions void all stakes and wins.

Triggered when one of the three collected bonus symbols is a super bonus symbol. The game starts on an 8×8 grid and all upgrade symbols affect all four gem types simultaneously. Five free drops are awarded, with the same rules as the regular bonus game applying. Pirots 4 distinguishes itself through its dynamic grid expansion from 6×6 to 8×8, triggered by corner bomb detonations. Each bomb receives a random bird colour at round start, creating strategic anticipation as birds move across the metallic space station. When a bird collects at a bomb’s position, the explosion removes a 3×3 area of gems and eliminates the corresponding space station section, transforming it into a tunnel.

So if you’ve upgraded your blue gems to level 3, a Wild collected by the blue bird counts as a level 3 blue gem. Gems are faceted crystals that come in four colours, each matching one of the birds. Every gem has five levels – they start at level 1 (no crown) and can be upgraded to level 5 (crown with a bright star). If you’re playing the demo version, you’ll see “DEMO PLAY” with a €5,000 balance in the information panel. Your bet and balance update after each spin, so you can track where you stand without any real-money risk. Pirots 4 maintains 94.0% RTP for base game and all five X-iter purchase modes.

The Pirots 4 demo game begins on a 6×6 metallic space station grid but expands to a maximum 8×8 configuration when corner bombs detonate. These corner bombs, positioned at each inner corner of the space station, receive random bird colours at the start of each round. Three top-rated slots similar to Pirots 4 offer creative mechanics and engaging bonus features.

Over extended play sessions, this difference becomes noticeable. For comparison, if you wagered 10,000 at 96% RTP, expected return would be 9,600 (400 loss). The 200 difference represents the impact of the lower RTP over the same volume of play. They’ll launch something like Cygnus, see it work, then build it into a five-part saga.

Visual intensity increases from dark to bright as levels rise. Established core mechanics of bird movement and gem collection that continue through subsequent versions. This parity allows accurate assessment of the game’s behaviour before committing real stakes. Extended demo sessions provide reliable indication of actual gameplay experience, including how frequently bonuses trigger and typical win sizes across different features. You’re playing the exact same game build as the real money version—same mechanics, same drop patterns, same RNG engine. The demo was last updated December 2024, keeping it identical to the live version.

Pirots 2 (ELK Studios) features cluster-pay wins, upgradable amber bird symbols, and persistent feature progress for larger payouts. Nitropolis 4 (ELK Studios) boasts Nitro Reels, 4096+ ways to win, cascading action, and up to 50,000x max win. Wild Toro 2 (ELK Studios) stands out with Walking Wild respins, dynamic action zones, and bonus-triggered multipliers, keeping gameplay highly interactive and varied. Landing three or more Bonus symbols activates the Bonus Game, where you receive a set number of free drops on an expanded grid. During this round, all symbol collection effects are amplified, and the chance to trigger additional features increases.

Unlike traditional cascading slots where symbols simply disappear, here each bird actively hunts gems of their colour whilst collecting every feature symbol they encounter. Instead, it engages players through continuous interaction – birds moving, symbols being collected, meters filling, grids transforming. The player is constantly watching for what the birds will do next, which turns passive spins into active viewing.

Instead, symbols drop in clusters, and bird characters interact with them on-screen. These parrots can collect, transform, or consume certain symbols, unlocking progression toward multipliers or unlocking the next game level. Cluster wins are formed by 5 or more identical symbols touching horizontally or vertically.

The CollectR mechanic works exactly as it would with real stakes. The demo runs on virtual credits—no card details, no hidden charges. You start with a play balance and can spin as much as you want to get a feel for the collecting birds and corner bomb mechanics. Regular Switcheroo randomly swaps two adjacent birds horizontally or vertically.

Your balance, settings, and game history synchronize automatically, creating a unified gaming ecosystem. Fresh off their wild west triumph, the fearful four’s celebrations were cut short when a space monster emerged through a black hole and snatched their treasure. With no time to lose, they dove into the vortex just before it sealed. Now, the mission to reclaim their stolen bounty begins – across the stars and beyond. I’ve spent over 7 years writing iGaming content through Upwork and for UK publications like Buzz Publishing, specializing in casino and game reviews including this one.

First game in the series introducing the collecting birds mechanic. Most straightforward implementation without the feature complexity of later entries. When collected by a bird, this coin instantly pays whatever amount is required to reach the 10,000x cap. For example, if you’ve already won 3,500x your bet, the MAX WIN coin pays the remaining 6,500x to hit the cap. Wilds substitute for any gem at whatever win level that gem is currently at.

How Does Pirots 4 Compare to Other Pirots Slots?

The Space Bandit does not collect Black Hole, Spacecorn, or Transform symbols, discarding them instead. It activates corner bombs when collecting at their positions and accumulates values and multipliers on its spaceship. The birds’ movements across the grid are fluid and full of personality, while features like grid expansions, explosions, and black holes add constant visual excitement. The cartoon-style graphics are crisp and detailed, ensuring the action looks great on both desktop and mobile devices. Complementing the visuals is an engaging soundtrack that perfectly matches the space adventure vibe—catchy, energetic, and never intrusive, even during extended play sessions. The combination of top-tier audio, playful animations, and a lively atmosphere creates an immersive experience that keeps players entertained from the first spin to the last.

Game continues until drops are exhausted or win cap is reached. Different gameplay mode focused on coin collection rather than gem collecting. These birds physically move around and collect symbols that touch them orthogonally (up, down, left, right – not diagonally). Each bird collects gems matching its own colour, plus any feature symbols it touches. The expandable grid from 6×6 to 8×8 transforms gameplay dynamically.

Pros and Cons of Pirots 4

Crucially, your progress on the symbol collection meter and gem payout levels carries over into the Free Drops, giving you a head start toward bigger wins. It detonates once the birds can no longer collect symbols, clearing a 3×3 area of the grid and removing part of the space station. This expands the grid — up to a maximum size of 8×8 — unlocking more symbols and boosting your win potential. Each corner of the space station grid contains a corner bomb, randomly assigned to one of the birds. When a bird collects a symbol positioned on top of a bomb that matches its colour, the bomb is armed. If an Alien Invasion, corner bomb, or other feature symbol was pending when the bonus game triggered, it activates as part of the first free drop.

Red hexagon gems (collected by purple bird):

Space StationBombs expand the grid size and allow the birds to move inside the space station, collecting up to 2 feature symbols per section. Pirots 4 takes players on a high-energy, interstellar adventure, starring a quirky crew of parrot astronauts in pursuit of their stolen treasure across the cosmos. The narrative picks up after the birds’ Wild West escapade, launching them into a galactic chase after a space monster snatches their loot through a black hole. This sci-fi theme is infused with humor and personality, blending the charm of cartoon birds with the intrigue of space exploration. The slot’s setting is a vibrant, ever-expanding grid that sits within a futuristic space station, where every spin feels like a new chapter in the birds’ cosmic quest. One bird teleports to the edge of the grid or to the next symbol it can collect along its trajectory.

Visually and conceptually, Pirots 4 is a swirling cocktail of psychedelic birds, alien tech, and treasure-fueled nonsense – but somehow, it works. Building on the identity of the previous Pirots titles, ELK has again crafted a grid-based adventure bursting with charm and chaos. The reels take place in an alien sky world, where animated parrots stomp across the board, eat symbols, and transform them into upgraded tiles, bonuses, or multipliers.

Pirots flips that—four cartoon parrots move across the grid, actively hunting down matching crystals and feature symbols like they’re on a treasure hunt. Each bird collects its own colour, and what they gather upgrades throughout the round, building from basic gems to crowned crystals worth serious money. It’s ELK Studios trying something properly different with the “CollectR” mechanic, and it worked well enough they’ve since made five sequels, including Pirots 4.
