FluxPlays verdict
Our verdict
No, unless you already enjoy CollectR's board-reading enough to accept a low return. The Yeti is the new idea: every bird it freezes doubles its multiplier, and in the Frozen Fury coin game that can climb very fast. The drawback is one low RTP for every mode, and in our base drops the bombs, Black Holes and clashes mostly moved birds around for small change.
Who it suits
Play this if…
- Puzzle-minded players: each drop is a board to read, with four birds collecting in turn
- Pirots fans: the Yeti's doubling multiplier and the Frozen Fury coin game are new to the series
- Bonus buyers who like a cheap feature: Frozen Fury costs half a Bonus and shows the game's best idea
Skip this if…
- Players who look at the RTP first: every mode shares one low figure
- Short-session players: base drops are slow, and most of the action pays a few dollars
- You want quick rounds: feature drops play out bird by bird, and a Bonus takes minutes

Pirots 4: Full Review
Pirots 4 sends ELK Studios' four collecting birds into a space station, where a Yeti can freeze them and every frozen bird doubles his multiplier. The CollectR rules stay as before: each bird moves around a 6x6 grid collecting gems of its own colour, and bombs grow the board toward 8x8. ELK released it in July 2025, and it suits players who like reading a busy board more than watching reels spin.

The base game before our first drop: four birds, gems and a corner bomb in each inner corner. FluxPlays demo test, 1 November 2026.
How Pirots 4 works
Each bird is paired with a gem colour. After a drop, every bird walks to touching gems of its colour, horizontally or vertically, collecting them along with coins and wilds, and keeps going until nothing is left in reach. Each gem pays by its colour and its level, and gems upgrade one level at a time up to level 7:
| Gem at $1 | Level 1 | Level 2 | Level 3 | Level 4 | Level 5 | Level 6 | Level 7 |
|---|---|---|---|---|---|---|---|
| Red | $0.10 | $0.25 | $0.40 | $0.75 | $2.00 | $6.25 | $30.00 |
| Purple | $0.10 | $0.20 | $0.30 | $0.60 | $1.60 | $5.00 | $15.00 |
| Green | $0.05 | $0.15 | $0.25 | $0.45 | $1.20 | $3.75 | $10.00 |
| Blue | $0.05 | $0.10 | $0.15 | $0.30 | $0.80 | $2.50 | $7.50 |
The last two levels are where the money is. A red gem at level 7 pays three hundred times its level 1 value, so upgrades early in a round shape every collection after them.
What feeds what:
- Gems and wilds the birds collect fill a meter, and a full meter turns random gems into feature symbols.
- Corner bombs take a bird colour, and a bird of that colour collecting on one sets it off, clearing gems and growing the grid toward 8x8.
- Spacecorn lets the birds cross empty spaces once. Clearing the whole grid while it runs starts the Frozen Fury coin game.
- Three bonus symbols collected in one round start the Bonus, or the Super Bonus if one of them is a super bonus symbol.
Frozen Fury carries the game for us, the Bonus is the long build, and the rest mostly moves birds around the board.
The Yeti and Frozen Fury: what freezes and what doubles
Yeti snack time drops a 4x4 freeze zone with a 2x2 Yeti in its centre. Every bird that ends up inside the zone freezes, and each frozen bird doubles the Yeti's multiplier, which then applies to that bird's collected value. A snowball can also set off one to four corner bombs at random.
Frozen Fury is the coin game built on the same idea. It plays on an 8x8 ice grid with the Yeti in a central freeze zone and a bird in each corner. Birds collect coins across ice bridges, and the game gives three drops that reset whenever coins, birds or ice bridges land. Each frozen bird doubles the Yeti again, so a round with several freezes can climb very fast.
Our natural one on spin 76 shows the scale. Spacecorn let the birds clear the board, and Frozen Fury started. With the multiplier panel at 36X, its payout step was $58.00, nearly the whole $60.95 round.
Our bought Frozen Fury: frozen birds doubled the Yeti to x128. FluxPlays demo test, 1 November 2026.
ELK's launch sheet calls the coin game Lost in Space and the monster the Space Bandit, and ELK built Pirots 4 to change after a countdown that started at release. The demo we played, with rules updated in August 2025, uses the Yeti, Frozen Fury and Yeti Snack Time, and this page follows it.
Other board features
Ten feature symbols can reach the grid. Besides the bonus symbols, the Yeti horn and Spacecorn, there are wilds, coins, an upgrade for one colour, an upgrade for all, and a transform. The Black Hole absorbs the whole grid and reshuffles it, and it can remove one to three birds and recolour their gems.
Birds also move each other. Switcheroos swap neighbouring birds, and when three or more end up side by side a Power Clash clears a 5x5 area and sends them flying through anything in their path. A blown-up station section becomes a tunnel that can hold up to two feature symbols, and at 8x8 space portals open in the corners.
The Bonus and X-iter: prices and what you get
Three bonus symbols collected in one round award 5 free drops, and every bonus symbol collected inside the round adds one more, except during a Power Clash. Grid size, meter progress and gem levels all carry over between drops. The Super Bonus plays on 8x8, and every upgrade lifts all gems.
X-iter is ELK's buy menu, open only in the base game:
| X-iter option | Type | Price at $1 | RTP and volatility (ELK) | What you get | Our test |
|---|---|---|---|---|---|
| Super Bonus | Bonus buy | $500 | 94.0%, 7 of 10 | Super Bonus: 8x8, every upgrade lifts all gems | One round: $163.35 back |
| Bonus Game | Bonus buy | $100 | 94.0%, 7 of 10 | 5 free drops | One round: $81.25 back |
| Frozen Fury | Bonus buy | $50 | 94.0%, 7 of 10 | The coin game, guaranteed | One round: $117.00 back |
| Yeti Snack Time | Mode, one drop | $25 | 94.0%, 7 of 10 | One drop with Yeti snack time; a Super Bonus if the Bonus triggers | One drop: $8.75 back |
| Bonus Hunt | Mode, per drop | $3 a drop | 94.0%, 7 of 10 | Four times the Bonus chance | 10 drops: $6.95 back |
The volatility rating is ELK's own, for the game as a whole. Every option shares the base RTP, so by the rules none is better value than another. We would pick Frozen Fury, the cheapest way into the feature that makes Pirots 4 different.

RTP, volatility and max win
ELK gives one RTP for the game and every X-iter mode, 94.0%, and the demo lists no other version. That is low next to most slots, and lower than Pirots 5. ELK rates the volatility 7 of 10, shown above as medium-high. A round stops at 10,000x the bet, and a MAX WIN coin pays whatever is left to reach it.

Played on ELK Studios' official demo (pirots4, client build 370870, rules updated 22 August 2025) in US dollars on 1 November 2026, in one session from a $5,000.00 balance: 100 base drops at $1.00, then each X-iter option, ending at $4,689.50 over 114 paid rounds, matching the game server's balance. The window rendered slowly, so the game's animation timer was driven by a script; game logic and server calls were untouched.
The extras fired constantly and paid little. Corner bombs went off on nine spins, the Yeti came twice and the Black Hole and Power Clash twice each, yet most of those rounds paid a few dollars. Frozen Fury made the session: without spin 76, the other 99 drops returned $56.25. Bonus symbols were collected on ten spins, never three in one round.
The buys split along the same line. Frozen Fury froze bird after bird until the Yeti reached x128, and it paid more than twice its price. The Super Bonus started on 8x8 with every upgrade lifting all gems, but its biggest single step was $92.50, and it returned about a third of its cost. A natural Bonus, a MAX WIN coin, a snowball and a space portal did not appear, so those come from the rules. Five X-iter rounds tell you how each mode plays, but with one shared RTP they say nothing about which returns most.
Spin 76 settled: the natural Frozen Fury paid most of the $60.95 round. FluxPlays demo test, 1 November 2026.
Our bought Frozen Fury settled at $117.00. FluxPlays demo test, 1 November 2026.
Our bought Super Bonus paid $163.35 over 5 free drops. FluxPlays demo test, 1 November 2026.
Is Pirots 4 worth playing?
No, unless the CollectR puzzle is already your kind of game. Pirots 4 is the busiest board in the series, with bombs, Black Holes, clashes and switcheroos moving the birds on almost every drop, and the Yeti adds a doubling multiplier the earlier games lack. The price is the return: one low RTP for every way to play, and a base game where most of that movement pays small change.

Pick Pirots 5 if you want CollectR at a higher RTP. Choose Pirots 4 when the Yeti and its doubling coin game are what draw you.
In the demo, buy Frozen Fury once and count the freezes. Each one doubles the Yeti, which shows the whole appeal of this game in a single round.
Frequently Asked Questions
How does the Yeti work in Pirots 4?+
Yeti snack time drops a 4x4 freeze zone with the Yeti in the middle. Any bird that ends up inside freezes, and each frozen bird doubles the Yeti multiplier, which applies to that bird's collected value. A snowball can also set off corner bombs. In the Frozen Fury coin game the same doubling runs across an 8x8 ice grid.
How do you trigger the Bonus in Pirots 4, and can you buy it?+
The birds must collect three bonus symbols in one round for 5 free drops, or a Super Bonus if one is a super bonus symbol. X-iter sells the Bonus Game at 100x the bet and the Super Bonus at 500x, and Frozen Fury, the coin game, at 50x.
What is the difference between Pirots 4 and Pirots 5?+
Both use CollectR birds on a growing grid with X-iter buys. Pirots 4 puts them in a space station with the Yeti and its doubling coin game, at one low RTP for every mode. Pirots 5 runs at a higher one. If the return matters most, Pirots 5 is the better pick.
