Slot Review

By Bo C. Crux
Pirots 4 online slot

Everything about this online slot is perfect. It offers excellent audio-visuals, an engaging theme and exciting gameplay. With so many different features, players can expect plenty of action at any stage of the game. And this slot packs some explosive power so that those who are lucky, can walk away with some nice payouts.

Pirots 4 Slot Features

This game is packed to the brim with all sorts of exciting features. What you can do is play a free Pirots 4 slot right away, buy a bunch of features and then go read the rules. Because there’s just too many things to learn, especially if you haven’t followed the Pirots saga.

CollectR Engine

At the heart of gameplay is ELK Studios’ popular CollectR mechanic that has been mimicked by other studios. The idea is that characters collect gems of their respective colors to get players some payouts. But collecting can only be done if diamonds of their respective color appear next to birds.

This mechanic is enhanced by cascades. Once some of the gems have been collected, others drop into empty spaces and another round of collections can get triggered. But it isn’t just gems that appear on the grid as there are a lot of feature icons that boost the chances of winning when collected.

Upgrades

Each diamond has seven levels, and each level pays more than the previous. For Pirots 4 online slot, the studio introduced a slightly different upgrade system. There are rockets with numbers 1, 2 and 3. These are upgrade icons, and the numbers represent the number of upgrade steps.

When the rockets are golden, upgrades apply not only to one type of diamonds, but to all of them. And they also come with 1, 2 and 3 steps. There are 7 levels, and there’s a huge difference in payouts between level 1 and 7 symbols. So, upgrades are definitely among the most desired features in this game. But they don’t happen too often, which is what you’ll find out after testing the slot in a demo.

Pirots 4 Slot Boosters

This game comes with all sorts of features. Just open the game rules file, and it seems that this document is endless. That’s how many things it has. In this review, we’ll consider most of the boosters. But you should know that there are more of them, and you can occasionally witness something you didn’t know exist in Pirots 4 video slot. Corner bombs, Charlie’s extra chance, Switcheroo, max win coin.

Space Station

The frame that marks the edges of the grid has another practical use. It’s an active space station that holds some nice stuff. But there’s no way to enter it unless one or more of the corner bombs go off. This creates entry points. Birds use them to enter the station and grab all the goodies left there. Each section can have up to 2 boosters.

Another use of the station is for teleporting. This happens if exiting from the opposite side of the station lands birds right in front of collectable diamonds. This teleporting is actually something that Pirots fans are familiar with from previous installments.

Power Clash

It has long been known that pirots don’t tolerate each other even though they don’t compete for the same resources. But the fight always breaks out when three of them are in each other’s face.

They eventually fly off in random directions, but there’s a lot of dramatic action as they engage in fighting. The action clears a 5×5 area and when birds fly off, they additionally collect all feature symbols that are in their way and activate corner bombs.

Spacecorn

Pirots 4 online slot review

A green alien octopus that comes in a popcorn box has a purpose. It seems like it attacks birdies with bad intentions, but it actually gives them a lift to new clusters of diamonds. That offers a good chance of clearing an entire grid. And when this scenario takes place, players enter the Lost in Space bonus that we’ll discuss later in this Pirots 4 slot review.

Transformation

Fire extinguishers can be used in space to move around, which is demonstrated in movies. Birds in the Pirots 4 slot machine use it to additionally transform diamonds to match the color of a bird. Or it transforms gems into feature icons.

Black Hole

Pirots 4 slot demo

When this feature gets activated, dramatic things happen as everything and everyone is sucked into the Black Hole. Luckily, all symbols reappear but land on random positions. However, this process can claim up to three birds as they won’t be returning.

Alien Invasion

That’s where the vulture called “Space Bandit” is creating chaos once again. This character appears out of nowhere and starts collecting columns of symbols. But when any parrot is collected, a fierce fighting breaks out inside a small space cabin. And the winner of this fight determines the further developments. If a pirot wins, the feature is over. If the Bandit wins, it boosts the multiplier, and the character is free to collect more symbols.

You’ll see that there are bombs in each corner of the grid. And when a laser hits any of them, the bomb explodes, removing a bunch of symbols and expanding a grid. When you load Pirots 4 free slot, buy the feature to explore its potential and possibly activate the bombs.

It’s obvious that pirots don’t want any competition in collecting diamonds. But they don’t have a choice. Once they stumble upon a special Alien Invasion feature, they themselves unlock the portal to let the vulture into their space.

Pirots 4 Bonus Games

The slot has two types of bonus rounds. One is a Hold & Win feature that has a slight modification. Another one is Free Drops. To enter the former bonus, you need to clear the whole grid during the Alien Invasion feature. And for Free Drops, you just need three alien skulls.

To explore both features, players can play the free Pirots 4 online slot and use the X-iter features. They can buy Hold & Win and both the regular and super versions of the free drops.

Lost in Space Bonus

At some point, pirots will be flying in open space unable to settle and start collecting diamonds. But even then, they still deliver gamblers some lucrative action. This time they are going for gold. And turns out there’s plenty of gold coins miles above the Earth.

Pirots 4 bonus features

It’s a Hold & Win bonus with a twist. Everything is similar to a traditional round of this type. But for Pirots 4 video slot, the studio decided to add some sort of blockers. They remain sticky and occupy space. The more of them, the less space it’s for coins to land.

Hold & Win is something the studio introduced in the third installment. It does add complexity, but considering this type of bonus is common and well familiar to players, this added complexity shouldn’t be overwhelming. Try Pirots 4 in free mode to see that the gaming experience is fun and light.

Free Drops

When 3 skulls are collected by birds, players get 5 free rounds with a grid size carried over from the main game. But if at least one of the alien skulls has three eye sockets, players get a fully expanded 8×8 grid right away. The feature can be extended. Players get +1 free drop for every 1 skull collected.

Pirots 4 Slot Stats

RTP is 94%, max win x10,000 and volatility is high (7/10). Surprisingly, these are stats all installments share. Hit frequency is 25%, meaning that you can expect a win on average every four rounds. In a world where adjustable RTP has become a norm, it’s a relief to see just one RTP setting. If you still want to make sure RTP is 94%, check the last page of the game rules.

Similar Slots

This slot series is one of the most recognized in the ELK Studio portfolio. The first release was the first time the studio introduced the CollectR mechanic. It also had the series of features that has shaped the foundation of the slot range.

The releases that followed offer more complexity but stay true to the original combination of features. That was until the release of Pirots X, where ELK Studios abandons CollectR and trades it for the cluster mechanic.

Pirots 4 marks the return to legendary CollectR. Even though the developer made the cluster engine feel as similar to CollectR as possible, the experiment must have been unsuccessful. So, thousands of Pirots fans should be relieved to see their favorite engine is back where it belongs.

Conclusion

Pirots 4 is an amazing online slot and a great addition to the series. It keeps the signature pack of features but also brings a couple of new things to give it a fresh feel. There are no innovative elements added, but it doesn’t matter because the product is so good already that a few tweaks is all it takes to make another exciting release.

That space theme and sleek audio-visuals complement this slightly refreshed set of features making the slot even more exciting. Overall, ELK Studios has done an excellent job making the slot feel fresh and familiar at the same time.
