Pirots 4 is a video slot developed by ELK Studios in collaboration with CollectR, released on 14 May 2025. This is the fourth entry in the Pirots series, featuring an expandable grid that starts at 6x6 and can grow to 8x8 through corner bomb detonations.
The game centres around four space-suited birds that move across the grid collecting matching coloured gems and feature symbols. Each bird has a distinct appearance: the purple bird wears a standard spacesuit, the red-orange bird has an antenna, the blue bird sports a blue suit, and the green bird wears protective goggles.
The slot uses a cascading symbols mechanic where winning combinations disappear and new symbols drop down. Unlike traditional payline slots, Pirots 4 requires birds to physically collect symbols by moving to adjacent positions. The game incorporates ten different feature types including corner bombs, space station tunnels, teleportation portals, Power Clash, Alien Invasion, Black Hole, and various bonus games.
The mathematical model delivers a 94.0% RTP with high volatility. Bet range spans from 0.20 to 100.00 per spin, with a maximum win capped at 10,000x your stake.
Pirots 4 builds on ELK's collecting birds system with significant additions. The expandable 6x6 to 8x8 grid creates more space as corner bombs detonate, removing station sections that then function as tunnels. Birds can move through these tunnels when symbols at both entrance and exit are collectable, picking up feature symbols along the way.
Space portals appear in corners once the grid reaches maximum size and that corner section is removed. Birds teleport between portals when collectable symbols sit on multiple portal positions. The Black Hole feature absorbs all symbols and birds, redistributing them randomly while potentially removing one to three birds and transforming gem colours.
The game stacks multiple mechanics: corner bombs, station tunnels, portals, Power Clash when three or more birds meet, Switcheroo movements, Alien Invasion column collecting, Spacecorn filling empty spaces, Transform symbol clusters, plus regular and super bonus games. This creates unpredictable combinations but requires investment to understand how features interact.
Pirots 4 works for players who want mechanical depth and don't mind spending time learning system interactions. The demo provides full access to test all features risk-free. High volatility and 10,000x potential appeal to those accepting extended dry spells for larger win potential. Players requiring 96%+ RTP or simpler mechanics should look elsewhere.
Triggered by collecting three bonus symbols (golden skull with "BONUS" text) during a game round. Awards 5 free drops starting at whatever grid size you were playing when triggered. Grid size, symbol collection meter progress, and gem payout levels all persist throughout the bonus game. Each bonus symbol collected during free drops awards one additional free drop. The bonus game ends when free drops are exhausted or the 10,000x win cap is reached.
Triggered when one of your three collected bonus symbols is a super bonus symbol (golden skull with "SUPER BONUS" text). Starts on an 8x8 grid with 5 free drops. All upgrade symbols affect all four gem types simultaneously rather than just one type. Same persistence rules apply as regular bonus game.
Triggered when a bird collects the red PRESS button symbol. The Space Bandit character appears and collects symbols column by column across the grid, activating features as encountered. When the Space Bandit meets a bird, a space duel initiates. Winning duels increases the Space Bandit spaceship multiplier. If a bonus game triggers during Alien Invasion, it's automatically upgraded to super bonus.
Triggered when the entire grid clears during the Spacecorn feature. Plays on an 8x8 grid with 3 starting drops. Landing coins or bridge symbols resets the drop counter back to 3. Game continues until drops are exhausted or win cap is reached. Different gameplay mode focused on coin collection rather than gem collecting.

X-iter costs range from minimum 0.60 to maximum 50,000.00. Feature only available in base game. All modes maintain 94.0% RTP.
When three or more birds end up horizontally or vertically adjacent and cannot collect more symbols, they trigger a Power Clash. Birds smash together, removing all symbols in a 5x5 area from the clash point, then fly away in random directions.
Collected Black Hole symbol activates when birds cannot collect more symbols. Absorbs all symbols and birds, redistributes them randomly, and can remove one to three birds. Gems matching removed bird colours transform to colours of returning birds.
Two adjacent birds have random chance to swap positions horizontally or vertically when stuck. Space Switcheroo moves one bird to grid edge or next collectable symbol.
Randomly triggered when birds cannot collect more symbols. Activates one to four corner bombs to continue action.
The maximum win in Pirots 4 is capped at 10,000 times your bet amount. When this cap is reached during any game round, the round ends immediately and pays out all wins collected to that point. At the minimum bet of 0.20, maximum win equals 2,000. At maximum bet of 100.00, maximum win reaches 1,000,000.
A special MAX WIN coin symbol can land on the reels. 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.
Maximum wins typically occur during bonus games, particularly super bonus with its 8x8 starting grid and enhanced upgrade symbols. The combination of high-level upgraded gems, multiple collecting birds, and extended free drops creates the highest win potential. Alien Invasion bonus rounds also show increased max win probability due to guaranteed super bonus if the feature triggers.
In the demo version, wins display in virtual credits matching your demo bet size. The mathematical model remains identical between demo and real money play, meaning win frequencies and potential max wins occur at the same rates. Demo mode provides accurate representation of how often you might approach maximum win scenarios.
Pirots 4 operates at 94.0% RTP across all game modes including base game, all bonus features, and all X-iter purchase options. This means that theoretically, over millions of spins, the game returns 94.00 for every 100.00 wagered. The remaining 6.00 represents the house edge.
This RTP sits 2% below the UK market standard of 96%. 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). At 94% RTP, expected return drops to 9,400 (600 loss). The 200 difference represents the impact of the lower RTP over the same volume of play.
The slot uses high volatility mathematics, meaning wins occur less frequently but tend toward larger amounts when they hit. You should expect extended periods without significant wins punctuated by occasional larger payouts. This volatility profile demands larger bankrolls relative to bet size to survive dry spells.
The expandable grid system, multiple feature interactions, and 10,000x max win potential all contribute to high volatility characteristics. Base game pays tend toward smaller amounts, with major wins concentrated in bonus games and especially super bonus rounds.
The demo version uses identical RTP and volatility to real money play. ELK Studios doesn't manipulate demo performance to appear more generous. Both modes run on the same mathematical model released on 14 May 2025. Win frequencies, bonus trigger rates, and payout distributions match exactly between demo and real money 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.
ELK Studios, founded in 2013, has built a catalogue of 145+ slots characterised by iterative game series and mechanical refinement. Rather than producing one-off titles, they develop franchises like Pirots (4 entries), Cygnus (5 entries), and Nitropolis (5 entries), each iteration evolving core mechanics.
The CollectR collaboration represents ELK's approach to feature mechanics. Their collecting birds system first appeared in earlier Pirots versions, with each sequel adding layers: cascading symbols, expanding grids, bonus variations, and now space stations, portals, and multiple bonus game types in Pirots 4.
Pirots 4 expands on Pirots 3 by adding space station tunnel mechanics, teleportation portals, Alien Invasion feature, Lost in Space coin game, and Power Clash. The grid expands from Pirots 3's maximum to 8x8, and X-iter options increase from three to five purchase modes. The fundamental collecting birds mechanic remains consistent, but feature density increases significantly.

| Symbol | Level 7 | Level 6 | Level 5 | Level 4 | Level 3 | Level 2 | Level 1 |
|---|---|---|---|---|---|---|---|
| Red Hexagon | 6.00 | 1.25 | 0.40 | 0.15 | 0.08 | 0.05 | 0.02 |
| Purple Hexagon | 3.60 | 1.00 | 0.32 | 0.12 | 0.06 | 0.04 | 0.02 |
| Green Diamond | 2.00 | 0.75 | 0.24 | 0.09 | 0.05 | 0.03 | 0.01 |

Click the bet amount displayed in the bottom right corner (shows "BET 1.00" by default). This opens a grid with 12 preset options ranging from 0.20 to 100.00. Select your stake - it glows cyan blue when active. Close the overlay by clicking the X or anywhere outside the menu.
The large circular button with refresh arrows in the bottom right controls spins. Click once for a single spin. For continuous spins, hold down the spin button to activate autoplay. Release to stop autoplay at any time. There is no separate autoplay button - the hold function handles automatic spins.
Access Settings through the hamburger menu (three lines, top left):
Click the blue "X-iter" button (bottom left) to open the bonus buy menu. Five purchase options appear ranging from 3x bet (Bonus Hunt) to 500x bet (Super Bonus). Select your preferred option and confirm purchase. X-iter only functions in base game - you cannot buy features mid-round.
Birds move horizontally and vertically to adjacent positions to collect symbols. Each bird collects gems matching its colour plus all feature symbols. When birds collect all available symbols and cannot move further, the round evaluates for features like Power Clash, Switcheroo, or Charlie's Extra Chance. New symbols then drop to fill empty positions.
Four corner positions contain bombs assigned random bird colours at round start. When a bird collects a symbol on its matching coloured bomb, the bomb detonates. This removes a 3x3 area, expands the grid by one row and column (up to 8x8 maximum), and removes that corner's station section.
In demo mode, your virtual balance resets automatically when depleted. Simply refresh the page or continue playing to receive a new demo balance. This allows unlimited testing of different bet levels and features without restriction.
The demo version eliminates all financial pressure. You test every feature, bonus round, and X-iter purchase option without spending money. This is particularly valuable for Pirots 4 given its mechanical complexity - understanding how corner bombs, portals, tunnels, and bird interactions work together requires multiple sessions.
Access the game immediately without creating accounts, submitting personal information, or providing payment details. Load the page and start playing. This removes barriers to testing whether the game suits your preferences before committing to casino registration.
Pirots 4 includes ten different feature types. The demo lets you experience each one: trigger bonus games naturally or purchase them through X-iter, see how Alien Invasion works, test Power Clash scenarios, experiment with Space Station tunnels, and understand portal teleportation mechanics. This comprehensive testing isn't practical when spending real money.
High volatility slots like Pirots 4 require understanding win frequency and size distribution. Demo mode allows extended sessions to gauge how often bonuses trigger, typical base game win sizes, and whether the 94% RTP produces acceptable gameplay experience for your preferences. Run 500+ spins to see realistic volatility impact.
Test different approaches to bet sizing, X-iter usage, and feature engagement without financial consequences. Try purchasing the 500x Super Bonus to see if the enhanced bonus game justifies the cost. Experiment with smaller base game bets versus larger bets with X-iter Bonus Hunt. Compare different bet levels' impact on session duration and win potential.
For players new to collecting birds mechanics or cascading symbol slots, the demo provides a learning environment. Understand how birds move, why they stop, what triggers different features, and how the expanding grid system functions. This knowledge transfers to better informed decisions if you later play for real money.
Test Pirots 4 alongside other slots in demo mode to determine which game suits you best. Compare its 94% RTP against alternatives offering 96%+. Evaluate whether its feature complexity adds value versus simpler mechanics. Assess if the collecting birds theme appeals more than other slot concepts.

The previous entry in the series, released before Pirots 4. Features the collecting birds mechanic with grid expansion but without space station tunnels, portals, or Alien Invasion. Offers different bonus structures and three X-iter purchase options instead of five.
Second iteration of the collecting birds concept. Established core mechanics of bird movement and gem collection that continue through subsequent versions. Simpler feature set than later entries.
First game in the series introducing the collecting birds mechanic. Foundation for all subsequent versions. Most straightforward implementation without the feature complexity of later entries.
Each Pirots version builds on previous entries while maintaining the core collecting birds concept. If Pirots 4's feature density feels overwhelming, earlier versions offer simpler implementations of the same fundamental mechanic.
The maximum win is capped at 10,000x your bet amount. At minimum bet of 0.20, maximum win equals 2,000. At maximum bet of 100.00, maximum win reaches 1,000,000. When the cap is hit, the game round ends immediately and pays out all collected wins.
Pirots 4 was released on 14 May 2025 by ELK Studios in collaboration with CollectR.
No. The demo uses identical RTP (94%), volatility, mathematical model, and features to real money play. Both versions run on the same game build released on 14 May 2025. Win frequencies and payout distributions match exactly.
Collect three bonus symbols during a game round to trigger the regular bonus game with 5 free drops. If one of those three symbols is a super bonus symbol, you trigger the super bonus game instead. Alternatively, purchase bonus entry through X-iter for 100x bet (regular bonus) or 500x bet (super bonus).
The MAX WIN coin symbol, when collected by a bird, instantly pays whatever amount is needed to reach the 10,000x maximum win cap. For example, if you've won 7,500x already, the MAX WIN coin pays 2,500x to hit the cap.
