Pirots 4 slot review: CollectR birds, Space Bandit and RTP
ELK Studios takes the Pirots birds into space: a 6x6 CollectR grid, a Space Bandit with its own multiplier and a single listed RTP of 94.0%.
The Pirots 4 slot is an ELK Studios game set in space, where bird characters collect matching symbols from a 6x6 grid instead of paying on lines. The product sheet gives a single RTP of 94.0%, a volatility rating of 7 out of 10 and a top win of 10,000x the stake. What follows traces a spin from the first collection to the bonus games, then turns to stakes and demos in Great Britain.

How the CollectR grid works in Pirots 4
ELK calls the mechanic CollectR. Each spin fills the grid, and the birds move across it picking up the symbols that match them. Collected symbols leave the grid, new ones fall in and the birds carry on while they can still reach a match. Several modifiers sit on top: bombs from the Space Station feature expand the grid, the Black Hole moves symbols and birds to new positions, and Alien Invasion is a further event listed by the provider. Symbol transformations and wilds complete the set, so one spin can run through several collection steps before it settles.
Space Bandit, Lost In Space and the bonus games
The Space Bandit is the character this instalment adds. It collects symbols as well and starts space duels that raise its multiplier. Clearing the grid completely triggers Lost In Space, a coin game, while bonus symbols lead to the Bonus and Super Bonus games. ELK puts the hit frequency at 25.0%, so about one spin in four returns something. A hit is not the same as a profit on that spin, and the larger results are concentrated in the features.
Pirots 4 RTP and the 7 of 10 volatility rating
ELK lists one figure, 94.0%, rather than a range of builds. Operators can still run their own configuration, so the in-game information screen is the place to confirm the Pirots 4 RTP at a given casino. RTP is a long-run average over a very large number of spins, and with a volatility rating of 7 out of 10 short sessions can land far from it in either direction. The slot volatility guide explains how the two measures differ.
X-iter, bonus buy and stakes for GB players
ELK's X-iter menu is its version of a bonus buy, with five modes running from Bonus Hunt at 3x the bet to Super Bonus at 500x. The product sheet gives bet levels of €0.20 to €100 or the equivalent in other currencies, but that range does not apply as written in Great Britain. Since 9 April 2025 the maximum stake on an online slot has been £5 per game cycle for adults, and since 21 May 2025 it has been £2 for players aged 18 to 24. Whether X-iter appears in a GB lobby, and at which prices, depends on the casino's build, so the game's own menu is the reliable source. The slot stake limits guide sets out the rules in full.
Pirots 4 demo and free play options
All British Casinos does not host games, so there is no Pirots 4 demo on this page. The official route is the provider's own website where a demo is offered, or a licensed casino that runs a demo mode. Since 7 May 2019 GB-licensed operators have had to verify age and identity before anyone uses a free-to-play version, so Pirots 4 free play at a casino starts with the same checks as a real-money account. The free slots page explains how demo modes work.
Inferno, Frozen Fury and the next sequel
ELK lists Pirots 4 - Inferno and Pirots 4 - Frozen Fury as separate pages under the same game id as the base game, and the series continues in the Pirots 5 review, which adds Captain Blackfeather and a Cursed Temple coin game. Among the operators carded on this site, Double Bubble Bingo names ELK Studios among its providers; the list beside this review shows where to look. Since 19 January 2026 a bonus spins offer tied to a slot like this one cannot carry wagering above 10x the bonus amount. Pirots 4 is for players aged 18 and over; limits, time-outs and support are on the responsible gambling page.
