The CollectR mechanic is the Pirots series. Four coloured birds roam a grid, collecting adjacent gems that match their colour — no paylines, no clusters in the traditional sense, just parrots physically moving across the board and eating symbols.
ELK Studios introduced it in March 2023 and it was unusual enough to generate real attention. It’s a slot that played more like a board game than a reel game, where wins are built through motion and momentum rather than static combinations landing in the right places.
Five entries followed in two years. Four of them run on the CollectR. The fifth — Pirots X — stripped it out entirely in favour of cluster pays, and that experiment tells its own story: the series came back stronger for it, with Pirots 4 representing the most ambitious build-out of the original concept yet.
What Separates Them?
Each title adds a new theme, a new villain, and a new layer of features while the core loop stays recognisable. The birds get a costume change. The grid grows. The feature list expands. The CollectR remains.
All titles run at 94% RTP and high volatility with a 10,000x max win, with the exception of Pirots X, which has a lower max win of 3,000x. Free play demos for the titles listed on this page are available above, with the full series breakdown below.
- Pirots (March 2023) — The original, and the one that introduced the CollectR to the market. Pirates and parrots on a 5×5 grid that can expand up to 8×8. Four coloured birds traverse the grid collecting matching gems; each gem has seven upgrade levels, and the feature meter fills with every collected symbol to release bonus features — wilds, transforms, upgrades, coins, bombs, and the bonus trigger. The bomb symbol is particularly consequential: it detonates when no more wins are in view, clears nearby symbols, removes birds temporarily, and expands the grid as a side effect. Getting the grid to 8×8 with upgraded gems already in play is where the top end concentrates. X-iter buy options from 3x to 500x. RTP 94%, high volatility, max win 10,000x.
- Pirots 2 (2023) — Prehistoric theme, 6×6 grid expanding to 8×8. The CollectR returns with one meaningful structural addition: the Popcorn symbol, which fills empty grid spaces so birds can cross gaps they’d otherwise be blocked by. In the original, an empty space stopped a bird in its tracks; Popcorn removes that constraint, opening up collection paths that wouldn’t otherwise exist. Amber symbols replace gems as the collecting currency. Super Bonus mode added alongside the standard bonus. RTP 94%, high volatility, max win 10,000x.
- Pirots 3 (2024) — Wild West theme, and by most accounts the commercial peak of the series. The CollectR core carries over from the first two entries, with the feature set refined rather than fundamentally altered. If Pirots introduced the concept and Pirots 2 added Popcorn, Pirots 3 sharpened everything into its most playable form — the iteration that converted the most players to the format. RTP 94%, high volatility, max win 10,000x.
- Pirots X (October 2024) — The outlier. Back to the pirate theme, but the CollectR mechanic is gone. Instead, ELK switched to cluster pays: five or more adjacent matching symbols form wins, cascading clears them, and the cycle continues. The birds are present but repositioned — they sit above the grid and only descend when a nest symbol lands, at which point a bird flies down and collects symbols of its colour to build the global multiplier. Three wild types (Split, Merge, Multiplier) interact with clusters and the global multiplier in combination. It’s a solid cluster slot and the familiar characters give it continuity with the rest of the series, but the absence of the CollectR changes the texture entirely. Grid is 5×5 expanding to 7×7. RTP 94%, high volatility, max win 3,000x.
- Pirots 4 — Lost in Space (July 2025) — Space theme, CollectR returns on a 6×6 grid expanding to 8×8. The villain this time is the Space Bandit, who initiates duels with birds via the Alien Invasion feature, collecting symbols and creating friction. Space Station Bombs expand the grid and allow birds to move inside the station, collecting up to two feature symbols per section. Clearing the entire grid during the Spacecorn feature triggers the Lost in Space coin game. Two bonus modes — Bonus and Super Bonus — both persistent with grid size and gem upgrade levels carried over from the triggering spin. RTP 94%, high volatility, max win 10,000x.
- Pirots 4 — Frozen Fury (August 2025) — First expansion to Pirots 4, released approximately one month after launch. Same 6×6 grid and CollectR foundation, with the Yeti replacing the Space Bandit as antagonist. Yeti Snack Time sees the creature freeze birds and double its multiplier each time it does, applying that multiplier to the frozen bird’s collected haul. Snowball symbols trigger corner bombs that expand the grid, and space portals play a more active role in repositioning birds across the grid. The Frozen Fury coin game replaces Lost in Space as the coin game trigger. Costumes change — the birds are now in fur coats — but the underlying structure is the same. RTP 94%, high volatility, max win 10,000x.
- Pirots 4 — Inferno (October 2025) — Final expansion to Pirots 4, arriving roughly a month after Frozen Fury. The birds land on a fire planet in heat-resistant gear and face Charlie, a mech-suited villain whose backstory connects back to the Space Bandit. Fire Minions are the new feature symbol: when a bird ends a move adjacent to a Fire Minion, it ignites and runs a fire marathon — a sequence of horizontal or vertical steps that leaves trails of gems and coins behind. The chain is contagious; a burning bird that finishes adjacent to another bird sets that one alight too. The Inferno coin game replaces Frozen Fury as the coin game trigger. The “don’t press” button — reached during the coin game — activates the Charlie feature, setting every bird on the grid ablaze simultaneously. RTP 94%, high volatility, max win 10,000x.
