Pirots 4 Slot Review

ELK Studios has really milked its "walking birds" mechanic, and Pirots 4 is basically their way of stretching that proven formula across three different games stuffed into one title.

When you boot it up, you're dropped into a lobby with three holograms, forcing you to pick between a space, ice, or fire theme before you even spin. Honestly? This is a sequel in the most literal sense. They didn't build a new house; they just rearranged the furniture. ELK markets it with fancy buzzwords like "time-based evolution," but underneath the fresh paint, it's the exact same collector mechanic they refuse to let go of. (Though, spoiler alert: the fire world hides a secret 9x9 coin game that quietly breaks the 8x8 limit they advertise on the tin).

For this review, let's look at the space world, "Lost In Space." It drops four parrots in spacesuits onto a grid of colored gems. At first glance, it looks like a standard cluster-pays slot, but it's actually a board game. The birds are game pieces that have to physically walk to their food. If the path is broken, they're trapped in the corner. The whole game revolves around this physical limitation, an empty square isn't just a blank space; it's a brick wall.

The numbers haven't changed much from the last game. You're looking at a 10,000x max win, which is great, but it's running on a stingy 94% RTP (Return to Player). The volatility is high, though technically a step down from Pirots 3, and you'll hit something on about 25% of your spins.

You start on a 6x6 board. The four birds eat gems that match their color, stepping into the empty spaces to keep eating until there's no matching food left next to them. Then, new symbols drop in.

Placement is everything. You could have a board flooded with high-paying red gems, but if the red bird is blocked from reaching them, you get nothing.

Gems start out paying pennies (0.05x your bet at the bottom) but can be upgraded up to 30x. You've also got bombs that blow out the grid, expanding it to an 8x8 size so the birds have room to roam and grab feature symbols. You'll see instant-win coins ranging from 1x to 2,500x, a "MAX WIN" coin, and "spacecorn" that lets birds walk over empty gaps.

There's also a meter at the top that fills up as birds eat. In the base game, eat 20 things, and it drops a feature symbol. But once you get into the bonus rounds, the game gets greedy: the meter price jumps to 30, then 40, then 50. It actively penalizes you for having a good run.

If you like buying features, ELK gives you five options, and some of them will make you want to pull your hair out:

• 3x your bet: Gives you a higher chance to trigger a bonus. (Spoiler: It often whiffs completely).
• 25x your bet (Alien Invasion): A bandit sweeps the board eating gems and birds. If it eats a bird, they duel. If the bandit wins, your multiplier goes up. If the bird wins, the feature ends. It's a weird mechanic where you are actively rooting against the game ending. I've seen this close early and pay out 8.9x on a 25x buy, leaving big coins just sitting out of reach. Infuriating.
• 50x your bet (Coin Game): The grid expands to 8x8 and drops coins. The catch? The birds are glued to the corners. They can only collect what's right next to them or connected by bridges. You can have a screen full of gold, but if a blank tile blocks your birds, you get nothing. Getting paid 1x on a 50x buy while a little alien holds up a "1X" sign feels like the game is mocking you.
• 100x your bet: The standard free drops (normally triggered by eating 3 skulls).
• 500x your bet (Super Bonus): This is where the game actually shines. It starts at 8x8, and every upgrade symbol boosts all colors at once. The board quickly fills with max-level gems and 100x coins. It's awesome, but it costs a fortune.

Pirots 4 sits in a weird spot. Compared to Pirots 3, the changes mostly just tighten the purse strings: the mid-level gems pay less, there are fewer wilds, the smallest coin value dropped from 2x to 1x, and the collection meter is more punishing.

But I have to admit... it is really fun to watch. Following these little birds around the board is incredibly entertaining, way more engaging than watching standard slot reels spin and cascade.

The reality of playing it, though, is a rhythm of mostly dead spins, broken up by small change, until the stars finally align and a bird gets a proper run at the grid. Mostly, you're just waiting around for three skulls to drop.

Here's my biggest issue: With ELK's own Concrete Cowboys and Pirots 5 both running at 96% RTP, the 94% return here feels like a steep tax on a game where you already have to fight for every square. There is no higher-RTP build of this one to go hunting for either, so that missing 2% is just the premium you pay to play in their fancy new lobby. Play it for the entertainment, but keep an eye on your balance.
