Pirots 4 Slot — Demo, RTP & How the Inferno Features Work

Pirots 4 is our CollectR™ slot set in deep space, released in 2025 as a game built to grow rather than sit still — it launched as Lost in Space, then we added two free world expansions on the same base game, Frozen Fury and Inferno. This page covers the Inferno world specifically, since that's the version we have complete screenshots and paytables for. RTP is a fixed 94.0%, the grid runs 6×6 expanding to 8×8, and the max win is our series-standard 10,000x the bet — up to €1,000,000 on the maximum stake. Checked and refreshed August 2026.

Pirots 4 Feature Symbols

	Symbol	Effect
	Bonus	Three collected in one round trigger the Free Drops bonus game
	Super Bonus	If one of the three triggering symbols is a Super Bonus, you get the Super Bonus game instead — guaranteed entry, maximum grid size
	Wild	Substitutes for any gem at its current respective payout level
	Coin	Pays its shown value × your current bet level — see the coin table below
	Spacecorn	Fills empty grid spaces once collected, letting a bird cross a gap to reach another cluster
	Transform	Turns a neighboring gem cluster into the collecting bird's color, and can convert some gems into feature symbols
	Upgrade	Lifts one gem color's payout level by 1, 2 or 3 steps, up to a maximum of level 7
	Upgrade All	Lifts all four gem colors' payout levels simultaneously by 1, 2 or 3 steps
	Fire Minions	Sets adjacent birds ablaze, starting a fire trail of mystery symbols that reveal gems or coins as it burns
	Charlie (Don't Press)	Reaching this button during the Inferno coin game sets every bird on fire; birds then collect any coins they walk past
	Black Hole	Absorbs all symbols and birds and drops them back into random positions — can remove up to three birds

Pirots 4 Bonus Game & X-iter

Land three Bonus symbols in a single round and you're into Free Drops — 5 of them to start. If one of those three triggering symbols happens to be a Super Bonus symbol, you skip straight to the Super Bonus instead: guaranteed entry, the grid locked at its maximum size, and every Upgrade symbol upgrading all four gem colors at once rather than just one. Grid size, collection-meter progress and every gem's payout level all carry over from the trigger spin into the bonus game rather than resetting.

Inferno adds two mechanics on top of that shared base. Fire Minions set adjacent birds ablaze, sending them on a fire trail that leaves mystery symbols behind — each one revealing a gem or a coin when it burns through. And if the entire grid ever clears out during a Spacecorn feature, it triggers the Inferno coin game: a dedicated coin-collecting round with its own grid, where reaching a red "Don't Press" button sets off the Charlie feature, setting every bird on fire so they can sweep up any coins they walk past.

Prices shown at €1 bet level — they scale with your stake. Availability can vary by operator and jurisdiction; some markets, the UK included, restrict bonus buys entirely.

Pirots 4 Max Win: Reaching 10,000×

The cap matches the rest of the series — 10,000x the bet, so up to €1,000,000 on the €100 maximum stake, exactly as stated on Pirots 4's own win-cap screen. There are two realistic routes there: stacking Coin symbols at increasing denominations until enough value has landed, or riding the Super Bonus, where the grid locks at its largest size and Upgrade symbols lift every gem color at once instead of just one. As with the rest of the CollectR series, the Super Bonus route is the more direct of the two — ordinary base-game play very rarely gets anywhere near the cap on its own.
