All upgrade symbols function as upgrade all symbols, upgrading every gem type simultaneously. If a bird can collect symbols at both the tunnel entrance and exit, it moves through the tunnel. Each tunnel section can reveal up to two feature symbols, which the bird collects whilst passing through. Bonus symbols appear as golden skulls marked “BONUS”. Collecting three of these during a game round triggers the free drops bonus game.

Super Bonus Game

The Bonus Free Drops feature begins when a Bird collects 3 Bonus symbols during a given round. During this feature, the win level and reel area remain at the level they were at when the feature was triggered. ELK Studios will release Pirots 4 on July 24, inviting players to join the adventurous birds on a mission to reclaim their stolen treasure across the galaxy. The slot introduces a 6×6 expanding grid and a range of innovative features that build on the series’ established gameplay. What’s exciting is the inclusion of unique bonus rounds such as the Pirate Plunder Bonus and the Squawk Free Spins.

Pirots 4 Overview

Lost in Space activates only when birds collect ALL symbols during Spacecorn feature. This 8×8 game places one bird in each corner with 3 drops. Birds collect only horizontally or vertically adjacent coins, using bridges to reach distant positions.

Volatility and Win Potential

If one of the three bonus symbols you collect is this variant, you trigger the enhanced super bonus game instead of the regular bonus. 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.

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. When three or more birds end up horizontally or vertically adjacent and cannot collect more symbols, they trigger a Power Clash.

• Up to three feature symbol releases can be held at once and are triggered together, ramping up the chaos and potential on the reels.
• When a bird collects a symbol on its matching coloured bomb, the bomb detonates.
• Pink-purple head plumage with a long, fluffy beard in matching colours.
• When 3+ birds become adjacent, they collide, removing gems in 5×5 area.
• Critically, Space Bandit does NOT collect Black Hole, Spacecorn, or Transform symbols, discarding them instead.
• The birds crash together into one position, removing all gems in a 5×5 area centered on the clash point.
• The circular spin button, bet selector, and menu options are designed for touchscreen use, whilst desktop players can use mouse controls with the same interface.
• Instead, four birds in spacesuits move around the 6×6 grid (expandable to 8×8), collecting gems that match their colour and all special symbols they encounter.
• Real-money slots in the UK should only be played on a UKGC-licensed casino.
• The demo version uses identical RTP and volatility to real money play.

Rewards potential

Four space station sections surround the main field, functioning as tunnels when removed by corner bombs.

Pirots 4 by ELK Studios represents a quantum leap in slot design, merging space pirates with advanced cascading mechanics on an expandable metallic space station. 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.

Space StationBombs expand the grid size and allow the birds to move inside the space station, collecting up to 2 feature symbols per section. This version starts on the maximum 8×8 grid regardless of your base game progress. More significantly, all upgrade symbols become upgrade all symbols—every single upgrade affects all four gem types simultaneously instead of just one.

Having issues with Huff N’ Puff CollectR ?

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. If you had red gems at level 4 when the bonus triggered, they stay at level 4 throughout all free drops. What’s interesting is how Elk Studios incorporates unique mechanics to keep gameplay fresh.

The circular spin button, bet selector, and menu options are designed for touchscreen use, whilst desktop players can use mouse controls with the same interface. These don’t pay directly (except coins), but they trigger effects when collected by birds. Spacecorn looks like a popcorn box with corn kernel eyes. When collected, it fills empty grid spaces with Spacecorn pieces, letting birds cross empty areas once to reach additional symbol clusters. Upgrade All symbols appear golden and also show 1, 2, or 3.

Expert Analysis: Why Pirots 4 Stands Apart

The Alien Invasion feature introduces genuine conflict. Space Bandit collects symbols column by column in random order, accumulating values and multipliers. When encountering birds, space duels determine outcomes. Bandit victories increase the spaceship multiplier and remove defeated birds for the feature’s duration. Bird victories end the invasion but apply accumulated multipliers before payout.

This knowledge transfers to better informed decisions if you later play for real money. When three or more birds become horizontally or vertically adjacent, Power Clash activates, though not during Lost in Space. Birds collide in one position, remove gems in a 5×5 area, then scatter horizontally, vertically, or diagonally. They automatically collect corner bombs, Alien Invasion symbols, Black Hole symbols, coins, and bonuses.

• The demo version uses identical RTP and volatility to real money play.
• This is the fourth entry in the Pirots series, featuring an expandable grid that starts at 6×6 and can grow to 8×8 through corner bomb detonations.
• Bonus symbols require three to trigger the bonus game with five free spins, whilst during bonus mode each additional bonus symbol adds one extra spin.
• Real-money slots in the UK should only be played on a UKGC-licensed casino.
• The circular spin button, bet selector, and menu options are designed for touchscreen use, whilst desktop players can use mouse controls with the same interface.
• Four space station sections surround the main field, functioning as tunnels when removed by corner bombs.

Wilds substitute for any gem at whatever win level that gem is currently at. 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. 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.

Coin Cat 2

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. Create a free account to keep it and get a weekly email when new slots like it drop. Pirots 4 runs as a browser-based HTML5 slot, requiring no downloads or installation. The game launches directly in your web browser on desktop computers, laptops, tablets and mobile phones, with the interface automatically adjusting to your screen size.

When birds collect all available symbols and cannot move further, the round evaluates for features like Power Clash, Switcheroo, or Charlie’s Extra Chance. 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.

Both the demo version and real-money play work the same way technically, loading instantly without additional software. ELK Studios built this with their Pirots 4 UK CollectR mechanic, so if you’ve played the earlier Pirots games, you’ll recognize the bones. If you haven’t, the demo’s your chance to learn before you decide whether to play for real. Each Pirots version builds on previous entries while maintaining the core collecting birds concept.

When they can’t collect any more symbols, various features might trigger to keep them moving. Established core mechanics of bird movement and gem collection that continue through subsequent versions. In demo mode, your virtual balance resets automatically when depleted.

Corner Bombs & Grid Expansion

Four gem types appear on the grid, each linked to one bird colour. Every gem has seven payout levels – they start at level 1 and can be upgraded to level 7 through upgrade symbols. Visual intensity increases from dark to bright as levels rise. The £1,000 balance gives you proper runway to figure out how this thing works. You’ll need it—there’s a lot going on with the collecting birds, expanding grid, and all those feature layers. Space portals appear in corners once the grid reaches maximum 8×8 size and that corner section is removed by a bomb.

Birds can’t finish a collection sequence on a Wild – if a bird lands on one, it moves to an empty position instead. The interface shows your balance bottom left (with a “DEMO PLAY” label if you’re in demo mode) and your current bet bottom right. At the top, you’ll see the CollectR logo and three skull indicators tracking bonus progress, plus a timer display showing the collection meter.

Been doing this since 2014, evolving from quirky one-offs into this serialised approach. Now juggling multiple active series simultaneously. This appears to be another feature symbol that interacts with the collection system.

Upgrade symbols enhance gems matching the collecting bird’s colour by one to three levels. Upgrade All symbols simultaneously boost all four gem colours. Wild symbols substitute for any gems at their current payout level, though birds cannot conclude collection on them.

Bomb Symbol

A black void surrounded by purple-blue glowing rings. Can remove one to three birds permanently; when birds are removed, all gems matching those bird colours transform into the colours of the remaining birds. When a bird collects a gem on a matching-coloured corner bomb position, the bomb detonates.
