Pirots 4 (ELK Studios) – Review & Demo Play

Pirots 4 - Game Overview

I jumped into Pirots 4 with the birds kitted out in space suits on a 6x6 grid using ELK's CollectR engine. Four birdonauts roam, collecting matching gems and feature symbols, then refills drop in and the chase continues until no more moves remain. Corner bombs can blow the space station and grow the board to 8x8, opening tunnels and portals. It’s high volatility with a 94% RTP and a 10,000x max win, so I treat it like a marathon, not a sprint.

RTP, Volatility and Max Win in Pirots 4

On paper Pirots 4 sits at 94% RTP with a hit rate around 25 per cent, and it feels punchy in practice. Sessions can whipsaw between quiet spells and cracking chains when the meter, upgrades and coins line up. It is a classic high variance ride, and I had runs where birds nibbled little, then a single cascade snowballed into a tidy haul. If you want steadier flow, accept the droughts and let the features build.

In the UK I’ve seen stakes from 20p to £5, and smaller, consistent bets kept me in the seat longer than cranking the stakes. That mirrors how the mechanics reward patience, as upgrades and grid size carry weight. The 10,000x cap is reachable through coin values, upgrade levels and strong free spins or Alien Invasion outcomes, but it doesn’t come easy. I bank my bigger pushes for moments when the grid has expanded and gem levels are trending up.

Symbols and CollectR Paytable in Pirots 4

Pirots 4 keeps the paytable tight. Four coloured gems sit on seven payout levels, with level 1 paying 0.05x to 0.1x and level 7 stretching to 7.5x through 30x depending on colour. Wilds stand in at the current level. Birds move horizontally or vertically to collect their colour plus feature symbols, then the refill drops fresh tiles. Above the grid a collection meter counts gems and wilds; fill it to store up to three pending feature symbol releases.

When the meter releases, random gems convert to feature symbols. You'll see scatters and super scatters, extra wilds, coin values including the Max Win coin, Upgrade and Upgrade All, Transform, Spacecorn, Black Hole, and Alien Invasion. Coins pay on collection, with the Max Win coin topping you straight to the cap. Upgrade icons push one colour or all colours up 1 to 3 steps, while Transform can flip a nearby cluster to the bird’s colour and even turn a few tiles into features.

Core Features and Grid Expansion in Pirots 4

Movement tricks matter. A Switcheroo can trigger when two birds end up adjacent with no more to collect, swapping places so one can reach a fresh symbol. A space Switcheroo can shift a bird to the edge or the next collectable in its path. When three or more birds bunch up, a Power Clash fires, clearing a 5x5 area and flinging the flock across the board, grabbing coins, bombs, Alien Invasion and other goodies in their flight paths.

Corner bombs sit at each corner and get a random bird colour. Land a collect on the matching light and the bomb arms, then detonates when movement ends. The blast wipes all birds, clears a 3x3 zone, and blows away that space station section. The grid can grow to 8x8, with the broken sections acting as tunnels that birds can traverse if both ends show collectables. Each tunnel can hide up to two feature symbols. Portals unlock at full size.

Two other keys shape the flow. Spacecorn fills empty cells so birds can cross gaps once each, opening routes to clusters you could not reach. Clearing the whole grid of collectables during Spacecorn triggers Lost in Space. Black Hole is the chaos button, swallowing symbols and up to three birds, then spitting them back in a fresh order. It can bin birds, which narrows what colours can score on the next drop, sometimes setting up tidy paths.

Bonus Features in Pirots 4

Free spins land when birds collect three scatters in the base game, giving five spins and +1 per extra scatter during the round. Progress is persistent, so your grid size, meter progress and any gem upgrades carry over. If one of the triggering scatters is a super scatter, the super bonus plays on an 8x8 grid where all upgrade symbols improve all gems. Any pending bombs, Alien Invasion or feature releases trigger on the first free spin.

Lost in Space arrives by clearing the board during Spacecorn. You get three drops on an 8x8 with a bird in each corner, and coins or bridge symbols reset the counter. At the end, birds collect adjacent coins, with bridges linking further grabs. Alien Invasion is the other headline. The Space Bandit sweeps columns, duelling birds and growing a spaceship multiplier when it wins. A bird win ends the raid and pays. Charlie’s Extra Chance can pop, lighting 1 to 4 corner bombs. X-iter buys range from 3x to 500x.

Frozen Fury and Inferno in Pirots 4

Two extra worlds shake things up. Frozen Fury swaps in a Yeti for the Space Bandit, with Yeti Snack Time freezing birds, stripping symbols, and doubling its multiplier as it strikes. The Frozen Fury coin game mirrors the flow, with frozen birds applying that multiplier to their haul. Inferno brings Fire Minions that set adjacent birds ablaze, leaving trails of gems or coins. Hit the "don't press" button and Charlie torches every bird. Black Hole still looms, and the volatility spikes hard.

Pirots 4 Slot Verdict

Pirots 4 sticks to the series core while piling on smart tweaks. The birds scoot, upgrade and clash, corner bombs open the map, and Alien Invasion can turn a drab spin into a belter. It isn’t a giant leap, and the 10,000x ceiling stays, but the polish, animation and pace kept me engaged. I had my best stretches once the grid expanded and upgrades stacked, so I play it patient, ride the swings, and let the engine build its moment.
