Pirots 4 by ELK Studios Slot Overview

Pirots 4 by ELK Studios keeps the collecting birds from the series’ previous numbered instalment, Pirots 3, and opens on a Space World map. Its three worlds, Lost in Space, Frozen Fury and Inferno, each have their own setting, signature feature and coin game, with a Yeti in Frozen Fury freezing the birds and multiplying their collected values.

The distinctive CollectR mechanic sends birds across an expanding grid to gather matching gems rather than form conventional winning lines. High volatility, gem upgrades and a coin game in each world add depth, with a maximum win of 10,000x the bet. Explore these features in the free demo on BonusTiime.

The max win is 10,000x the bet.

Pirots 4 Slot Features

Birds move, collect matching gems and trigger layered features, while Spacecorn, Black Hole, Power Clash and Yeti Snack Time add extra movement, resets and payout shifts to Pirots 4. The game is played in three worlds, Lost in Space, Frozen Fury and Inferno: the shared features come first, then the Yeti Snack Time and coin game of Frozen Fury, and the last sections sum up the other two worlds.

Symbol Collection

Four birds move horizontally or vertically to collect symbols of their own colour, plus all feature symbols. Gems can upgrade to payout level 7, and the symbol collection meter tracks collected gems and wild symbols until no bird can move.

Feature Symbols

Pirots 4 uses ten feature symbols that affect movement, upgrades and bonus triggers. Feature symbol releases convert random gems into feature symbols, each with a defined role in the board flow and bonus chain.

• Bonus: contributes towards the Bonus Game trigger.
• Super Bonus: triggers the Super Bonus Game when included among the three collected bonus symbols.
• Wild: substitutes for any gem at its current payout level.
• Coins: pays its collected value times the active bet level.
• Upgrade: raises one gem by 1, 2 or 3 steps.
• Upgrade All: raises all four gems by 1, 2 or 3 steps.
• Transform: changes a cluster of nearby gems to the bird’s colour.
• Spacecorn: fills empty spaces so birds can cross them once.
• Black Hole: absorbs all symbols and birds, then redistributes them.
• Yeti Horn: triggers Yeti Snack Time later in the round in Frozen Fury; this slot is the Alien Invasion symbol in Lost in Space and the rocket in Inferno.

Power Clash

When three or more birds end up horizontally or vertically adjacent and cannot collect more symbols, they trigger Power Clash, except during the coin games. The birds clash into one position, removing gems in a 5×5 area, then fly away horizontally, vertically or diagonally. It can also collect or activate certain features in the paths of the flying birds.

Space Portals

Space Portals let birds teleport between corners once the grid reaches maximum size and a corner space station section has been removed. The mechanic keeps movement active across the board and creates extra routing options when collectable symbols sit on two or more portals.

Space Station

The Space Station surrounds the grid and works as a tunnel when bombed sections disappear. Birds can move through it if they can collect symbols at both ends, and each section can reveal up to two feature symbols as they pass.

Corner Bombs

Corner Bombs sit in each inner corner of the space station and carry a random bird colour. If a bird collects a symbol on top of a bomb matching the bird’s colour, the bomb activates and detonates when collection stops, removing all birds, all gems within a 3×3 area and the connected station section. Each detonation expands the grid, up to 8 rows by 8 columns, before new symbols drop in and the birds return.

Yeti Snack Time

In the Frozen Fury world, Yeti Snack Time starts when a bird collects a Yeti horn symbol, then activates once the birds can no longer collect symbols. A 4×4 freeze zone appears with a 2×2 Yeti in its centre. A bird that ends up in the freeze zone is frozen and removed, doubling the Yeti multiplier, which applies to that bird’s collected value. A snowball can also detonate one to four corner bombs during the feature.

Frozen Fury

In the Frozen Fury world, the Frozen Fury coin game triggers when the whole grid is cleared during Spacecorn. It starts with a bird in each corner, some coins and 3 drops on an 8×8 board, and landing coins, birds or ice bridge symbols resets the counter to 3. A 4×4 freeze zone with the Yeti stays in the centre: a bird frozen there doubles the Yeti multiplier, which applies to its collected value.

Bonus Game

The Bonus Game starts when birds collect three bonus symbols during a round, and it awards five free drops. Collected bonus symbols add one more free drop in bonus mode, except when collected during the Power Clash feature. The symbol collection meter and the gem payout levels are kept throughout the Bonus Game.

Super Bonus Game

The Super Bonus Game triggers if one of the three collected bonus symbols is a Super Bonus symbol. It begins on 8 rows and 8 columns, and all upgrade symbols upgrade all gems.

Lost In Space

In Lost in Space, the Alien Invasion symbol sends the Space Bandit to collect symbols column by column. Each bird it meets starts a space duel: a win for the Space Bandit raises the spaceship multiplier, while a bird that wins ends the feature with that multiplier applied to the collected value. In the Lost in Space coin game, coins and bridges land during three drops and the birds only collect at the end, and birds linked by the same coins pass their value on to the next bird.

Inferno

In Inferno, the rocket symbol brings in up to four Fire Minions. A bird next to one catches fire and runs a fire marathon, leaving mystery fires that reveal gems or coins, with bigger coins where it runs over the same spot several times. The Inferno coin game starts with four Fire Minions and a don’t press button in the centre, and a bird that reaches the button triggers the Charlie feature, which sets every bird in view on fire.

X-iter

X-iter lets players buy direct feature entries and extra trigger chances from the base game. Each option has a fixed cost and a specific mode, so it changes how quickly the game reaches its bonus systems.

• Super Bonus: x500 the bet; guarantees the Super Bonus Game.
• Bonus Game: x100 the bet; guarantees the Bonus Game.
• Frozen Fury: x50 the bet; guarantees the Frozen Fury coin game (Lost in Space or Inferno coin game in the other worlds, same price).
• Yeti Snack Time: x25 the bet per spin; triggers Yeti Snack Time for one drop (Alien Invasion or Fire Minions in the other worlds), with Super Bonus guaranteed if the Bonus Game is triggered.
• Bonus Hunt: x3 the bet per spin; quadruples Bonus Game trigger chance.

Pirots 4 Slot Review

Pirots 4 stands out immediately with its three space worlds, from ice to fire, cartoon birds and metallic board framing. The visual identity comes from how the birds, gems and station paths interact on the grid, rather than from decoration alone. That gives the game a clear mechanical personality as well as a strong theme.

The strongest part of Pirots 4 is the CollectR system, because birds move to collect symbols instead of relying on standard spins alone. High volatility and a 10,000x cap create a sharper swing profile, while the bonus layers and grid expansion give the round structure real room to develop.

Pirots 4 develops its rounds through gem upgrades, grid-expanding bombs and the bonus chain. The main limitation is the 94.00% RTP, which sits below the best returns in the category, but the game still offers enough depth and variety to justify its rating.
