Pirots 4 is an online slot developed by ELK Studios and released on July 24, 2025. The fourth main instalment in the Pirots series takes the four colourful parrots into outer space, where they encounter alien enemies, mysterious portals and an unusual collection of bonus features.
The game retains the distinctive CollectR mechanic introduced in the original Pirots, where parrots collect matching gems rather than forming traditional paylines.
Pirots 4 starts with a 6×6 grid that can expand to 8×8. It has a theoretical RTP of 94%, medium-high volatility and a maximum advertised payout of 10,000× the stake.
The game also includes two additional worlds, Frozen Fury and Inferno, each introducing its own setting and gameplay variations.
Theme and Visual Design
Pirots 4 begins in outer space, with the four parrots exploring a mysterious space station after following an alien creature through a black hole.
The original environment features distant planets, asteroids and a metallic playing grid surrounded by space-themed machinery.
The colourful parrots remain the main characters, representing blue, green, purple and red.
The game later received two additional environments.
Frozen Fury introduces an icy planet inhabited by a Yeti, while Inferno takes place on a fiery world featuring Charlie the mech and his fire minions.
These additional worlds provide visual variety while retaining the series’ familiar collection-based gameplay.
Gameplay and CollectR Mechanics
Pirots 4 uses ELK Studios’ CollectR mechanic.
Instead of relying on conventional paylines, the four parrots move across the grid and collect gems matching their respective colours.
A parrot can collect a matching gem when it appears directly above, below, left or right of its current position.
Diagonal collection is not possible through the standard mechanic.
When a parrot collects a symbol, it moves into that position and can continue collecting additional adjacent gems.
The collection sequence continues until no further eligible symbols can be reached.
Special symbols can extend these sequences by transforming gems, creating new paths or activating additional features.
Gem Symbols and Upgrades
Pirots 4 features four gem colours, each with seven payout levels.
Collecting Upgrade symbols increases the value of the gems.
At their highest levels, the gems offer the following values:
| Gem Colour | Maximum Value |
|---|---|
| Blue | 7.5× stake |
| Green | 10× stake |
| Purple | 15× stake |
| Red | 30× stake |
Regular Upgrade symbols improve one gem colour, while Upgrade All symbols improve every colour.
Depending on the symbol, upgrades can increase gem values by one, two or three levels.
These upgrades become particularly important during bonus rounds, where their progress remains persistent between spins.
Special Symbols and Features
Pirots 4 includes several symbols that interact with CollectR.
Wild Symbols
Wild symbols can substitute for regular gems and can be collected by any parrot.
They help extend collection sequences and can contribute to the Collection Meter.
Coin Symbols
Coin symbols carry instant cash values expressed as multiples of the selected stake.
Collecting a Coin awards its displayed value.
A rare maximum-win Coin can award the game’s advertised maximum payout of 10,000× the stake.
Transform Symbols
Transform symbols change nearby gems into the colour of the collecting parrot.
This can create additional collection paths and extend the current sequence.
Spacecorn
Spacecorn fills empty grid positions with symbols that parrots can cross once.
This allows them to reach gems and special symbols that would otherwise be inaccessible.
The mechanic is also connected to the Lost in Space bonus feature.
Black Hole
The Black Hole feature absorbs symbols and up to three parrots before redistributing them across the grid.
Depending on the outcome, fewer parrots may remain active.
This can significantly change the available collection paths and the colours that can still be collected.
Collection Meter
Pirots 4 includes a Collection Meter that tracks collected gems and Wild symbols.
When the meter fills, a feature award is stored.
Up to three awards can be stored during a collection sequence.
Once the parrots can no longer collect symbols, the stored feature symbols are introduced onto the grid.
These awards can include Wilds, Coins, Upgrades, Transform symbols and other special features.
The Collection Meter creates opportunities for additional activity after the initial collection sequence has ended.
Power Clash and Switcheroo
Pirots 4 introduces two mechanics involving direct interaction between the parrots.
Power Clash
Power Clash activates when three or more parrots become adjacent to each other.
The parrots engage in a fight that removes symbols within a 5×5 area.
They then move in random directions, collecting and activating special symbols along their paths.
This can clear large sections of the grid and create new collection opportunities.
Switcheroo
When two parrots become adjacent, they may swap positions if doing so creates an opportunity to collect additional gems.
Switcheroo allows the parrots to access collection paths that would otherwise be unavailable.
Alien Invasion
Alien Invasion is one of Pirots 4’s main features.
During the feature, a Space Bandit appears above the grid and moves between randomly selected columns.
The Bandit collects gems and most special symbols as it travels.
If it encounters a parrot, the two characters enter a duel.
When the Bandit wins, its multiplier increases by one and the defeated parrot is removed for the remainder of the feature.
If a parrot wins, Alien Invasion ends and the accumulated prize is awarded with the applicable multiplier.
If all four parrots are defeated, the Bandit collects the remaining eligible symbols and awards its accumulated prize.
Additional Coin symbols are then introduced onto the grid.
The feature creates opportunities for multipliers and larger collections, although outcomes remain random.
Space Station and Portals
The playing grid is surrounded by a space station divided into four sections.
Certain corner positions can activate explosions when collected by the appropriate parrot.
These explosions destroy sections of the station and expand the grid.
Pirots 4 begins with a 6×6 layout and can eventually reach 8×8 positions.
The remaining station sections can also function as tunnels.
Parrots may travel through these tunnels when matching symbols are available at the entrance and exit.
Special symbols can sometimes be collected during the journey.
Once the grid reaches its maximum size, portals appear in the corners.
These portals allow parrots to travel between different parts of the grid, creating further collection opportunities.
Lost in Space Bonus
Lost in Space is a separate bonus feature that activates when the entire grid is cleared during the Spacecorn mechanic.
The feature takes place on an 8×8 grid.
It begins with three drops, which reset whenever a new qualifying symbol lands.
Only Coin symbols, bridges and empty positions can appear.
Each parrot occupies a corner of the grid.
The objective is to connect groups of Coins to the parrots using the available bridges.
Connected Coin values are collected when the feature concludes.
Lost in Space introduces a different style of gameplay from the standard CollectR mechanic.
Bonus Game and Super Bonus Game
The regular Bonus Game activates when three Bonus symbols are collected during the same base-game spin.
The feature begins with five free drops.
Several elements remain persistent throughout the bonus:
- Grid expansion.
- Gem upgrade levels.
- Collection Meter progress.
Each additional Bonus symbol collected during the feature awards one extra free drop.
The Super Bonus Game activates when the triggering combination includes at least one Super Bonus symbol.
Super Bonus begins with the grid expanded to its maximum 8×8 size.
Additionally, all Upgrade symbols improve every gem colour.
This creates greater opportunities to increase gem values throughout the bonus.
However, neither bonus guarantees a profitable result.
X-iter and Bonus Buy Options
Pirots 4 includes ELK Studios’ X-iter system.
Players can purchase specific gameplay conditions at different costs.
| X-iter Option | Cost | Feature |
|---|---|---|
| Bonus Hunt | 3× stake | Approximately four times the normal chance of triggering the Bonus Game |
| Alien Invasion | 25× stake | Guaranteed Alien Invasion |
| Lost in Space | 50× stake | Guaranteed Lost in Space feature |
| Bonus Game | 100× stake | Direct access to the regular bonus |
| Super Bonus Game | 500× stake | Direct access to Super Bonus |
The Super Bonus purchase begins with the maximum grid size and enhanced upgrade mechanics.
All X-iter options involve additional upfront costs and do not guarantee profitable outcomes.
Availability depends on the casino and applicable regulations.
Frozen Fury World
Frozen Fury is an additional world introduced after the original release.
It replaces the space environment with an icy setting featuring a Yeti.
Many of the core mechanics remain similar, but several features receive new variations.
One of the most important changes is Yeti Snack Time, which replaces Alien Invasion.
During this feature, the Yeti freezes parrots entering its area.
Each frozen parrot doubles the Yeti’s multiplier.
The resulting multiplier can increase the value of collected prizes.
Frozen Fury also introduces an icy variation of the Coin Game, where connected Coin values can receive additional multipliers.
The world offers a different presentation and feature interactions while retaining the CollectR foundation.
Inferno World
Inferno is the third world available in Pirots 4.
It takes place on a fiery planet where the parrots encounter Charlie the mech and his fire minions.
One of the main additions is the Fire Minions mechanic.
Fire Minions can ignite nearby parrots, causing them to move rapidly across the grid and leave trails of gems and Coins behind.
The Inferno Coin Game also introduces a special button.
When activated, Charlie sets all four parrots on fire, triggering additional movement and symbol interactions.
Inferno provides another variation of the familiar collection mechanics, with an emphasis on explosive effects and unpredictable movement.
RTP and Volatility
Pirots 4 has a theoretical RTP of 94%.
This is below the approximately 96% RTP offered by many other online slots.
The game is classified as medium-high volatility.
Its reported hit frequency is 25%.
These figures describe the game’s theoretical mathematical characteristics and do not predict the outcome of individual spins.
Players should verify the active RTP in the game information menu before playing.
Maximum Win and Betting Range
Pirots 4 offers a maximum advertised payout of 10,000× the stake.
The largest potential wins depend on valuable Coin symbols, upgraded gems and combinations of special features.
The referenced betting range is 0.20 to 100 per spin.
Betting limits may vary depending on the casino, currency and game configuration.
The maximum payout is a theoretical limit rather than an expected result.
Mobile Compatibility
Pirots 4 is available on compatible desktop computers, smartphones and tablets.
The game’s colourful graphics and animated characters translate well to mobile devices.
However, the expanding grid and numerous special features can make the interface busy on smaller screens.
Players unfamiliar with CollectR may need some time to understand the different mechanics.
Pirots 4 vs Pirots 3
Pirots 4 continues the CollectR formula established in the earlier games.
Both titles feature four parrots, collectible gems, upgrades, expanding grids and several interacting special features.
However, Pirots 4 introduces a space-themed setting, Power Clash, Alien Invasion, Black Hole and a new Lost in Space bonus.
The Space Station and Portals mechanics also provide additional ways for parrots to move across the grid.
Another major difference is the addition of Frozen Fury and Inferno, which introduce alternative environments and feature variations.
While Pirots 3 focused on Wild West adventures and character interactions, Pirots 4 expands the series with more elaborate movement mechanics and multiple worlds.
Slotinia’s Verdict on Pirots 4
Pirots 4 is one of the most feature-rich releases in ELK Studios’ Pirots series.
Its greatest strength is the variety of mechanics built around the familiar CollectR system.
Power Clash, Alien Invasion, Portals and Lost in Space all introduce different ways to interact with the playing grid.
The additional Frozen Fury and Inferno worlds also provide more variety than earlier releases.
However, the game can be difficult to understand initially because of the large number of special symbols and interacting mechanics.
The 94% RTP is another notable consideration, particularly when compared with slots offering higher theoretical returns.
Overall, Pirots 4 is a creative and ambitious sequel that successfully develops the series while retaining its distinctive identity.
Responsible Gambling
Pirots 4 is a game of chance involving financial risk.
Its RTP, hit frequency and maximum advertised payout do not guarantee any particular outcome.
The X-iter options can significantly increase spending, particularly the 500× Super Bonus purchase.
Players should verify the active RTP, understand the game’s mechanics and establish a budget before playing.
Gambling should always be treated as entertainment rather than a source of income.
