×10,000Max WinThree moments set the rhythm of a Pirots 4 round — from a normal CollectR pass across the grid to the corner-bomb expansions and bonus rounds it can unlock.
The four astronaut birds start at the edges of the 6×6 grid and move inward step by step, collecting every matching coloured gem, coin and feature symbol in their path. Once a bird can't move any further, its haul pays out and new symbols drop in to refill the board.
Bomb tiles sit in each corner of the grid. Detonate one and the board expands — up to a full 8×8 — opening tunnels that can reveal extra coins, wilds and feature symbols for the birds to collect.
Collect enough Bonus symbols in a round for free drops, enough Super Bonus symbols for the bigger version straight onto an 8×8 grid, or clear the whole board to launch Lost in Space.
The expanding grid keeps every round unpredictable, the CollectR birds mean there's no payline to track, and the Alien Invasion and Bonus features are what turn an ordinary pass into a Big Bang payout.
No fixed paylines — the birds collect matches as they move, and Corner Bombs can grow the board mid-round for more space to collect in.
The Space Bandit takes on the birds column by column in a duel-style feature, stacking its multiplier with every bird it gets past.
Collect Bonus symbols for free drops, or Super Bonus symbols for an enhanced round that always starts on a full 8×8 grid.
Built for big, infrequent hits — roughly a 1-in-4 spin hit rate, with the potential for a monster Big Bang payout.
Four moments from real gameplay — from a chained Big Win to the top-tier Big Bang payout.
Pirots 4 runs directly in the browser on desktop, tablet and phone, with no app to install. The expanding grid, CollectR birds and bet controls stay clear and easy to read at any screen size.
Pirots 4 keeps a tight symbol set built entirely around the CollectR idea: four coloured Wild gems tied to the four astronaut birds, a run of coin values the birds pick up along the way, and Bonus / Super Bonus symbols that unlock the feature rounds.
There's no payline chart to memorise here — the table on the right shows the full symbol set, and the block below explains the three that really shape a round.
Pirots 4 doesn't use paylines: the four birds collect matching symbols as they move across the grid, and every match adds to that round's payout. Exact coin values and payouts vary by operator — check the in-game paytable for the current numbers.
| Symbol | Type | Role |
|---|---|---|
| Coloured Wild gems | Wild | Matches its bird's colour |
| Gold Wild gem | Wild | Collected by any bird |
| Bonus skull | Bonus | Collect enough → Free Drops |
| Super Bonus skull | Bonus | Collect enough → Super Bonus (8×8) |
| Coins (50 – Max Win) | Collectible | Cash value added directly |
| Astronaut birds (4 colours) | High-value | The 4 collectors themselves |

Yes, most operators offer a demo mode with no registration and no real bets — a good way to get a feel for the CollectR mechanic and the corner-bomb grid expansion before playing for real money.
It's ELK Studios' name for the way the four astronaut birds move across the grid: each one travels step by step, gathering every matching gem, coin and feature symbol in its path, and pays out once it can't move any further.
It's a high-volatility slot with roughly a 1-in-4 spin hit rate — quieter stretches between wins, but the corner-bomb grid expansion and bonus rounds mean a single round can pay dramatically more, up to 10,000× the bet.
Pirots 4 runs in the browser on both desktop and mobile devices, with no app installation needed.
