Today, I’m offering a review of the sequel to the popular series, the Pirots 4 slot from ELK Studios. Released in 2025, this slot is the fourth game in the developer’s Pirots series. It’s not just a graphical update, but a completely new game with exciting mechanics like Alien Invasion, Lost in Space, Corner Bombs, Spacecorn, Black Hole, Charlie’s Extra Chance, and many more. This is a significant update, and I’ll strive to examine all its details. Previous slots in the series were renowned for their graphics, high winning potential, and dynamic gameplay. Let’s see if they’ve managed to maintain these qualities.
This new product is characterized by high volatility and a 94% RTP. These aren’t ideal for beginners, as the win frequency is low, but high rollers will certainly appreciate its full potential. The maximum win is 10,000 times the stake, and various bonuses can turn a small bet into a big win. But let’s discuss everything in more detail.
In Pirots 4, you’ll meet the familiar parrots again, but this time the main characters are off to space. You’ll visit a space station, collect gems from different levels, and discover the vastness of space. As in previous versions, the game is packed with animations, visual effects, and videos. It’s not just an online slot; it’s a game with a captivating storyline, which is quite rare. The graphics are impeccable: they’re high-quality and will delight even the most demanding players.
The sound design perfectly suits the space theme. Mysterious sounds and monotonous music remind us of the vastness of our universe. The playing field, rewards, bonuses, etc., are also well represented.
I would like to draw your attention to the mobile version of the slot machine. Perfectly optimized, it is available on all Android and iOS devices, directly in your browser. The graphics quality of the mobile version is in no way inferior to that of the PC version.
Pirots 4 uses a unique CollectR mechanic. There are no paylines, combinations, or typical groups. There are parrots and gems. Each parrot collects gems of its color and moves horizontally or vertically. There are 5 gem levels: the higher the level, the greater the payout. The parrot moves along the gems until they touch horizontally or vertically.
After each win, a cascade is triggered, and the birds continue collecting if there’s anything left to collect. Collecting symbols of the same color fills the meter, thus activating various bonuses.
The amount of your winnings depends on your bet; you can choose it at the start of the game or before each new round. The betting range varies from $0.20 to $100 per round, allowing you to apply almost any strategy, whether you’re a beginner or a high roller.
The highest paying symbols are represented by red gems. They offer multipliers ranging from x0.1 to x30 for each gem collected. The blue gem offers the smallest payouts, ranging from x0.05 to x7.5 euros. Larger payouts are linked to bonuses, which we will discuss later.
It is for its unique bonuses and mechanics that I highly recommend trying the Pirots 4 slot machine. All these unique features require a little more study time, but it is worth it.
The gems visible on the game board can be upgraded using a special “Upgrade” symbol. This mechanism makes the basic game mode very profitable: sometimes just winning 1 or 2 more points is enough to significantly increase your winnings.
On the game board, you can land the following special symbols: Wild, Coin, Upgrade, Upgrade-All, Transform, Spacecorn, Black Hole, Bonus, Alien Invasion. You can also land up to 3 special symbols on the grid. They all activate random functions, thus increasing the online slot machine’s winning potential. Here are the functions of the special symbols:
This is a rare feature activated by collecting the Alien Invasion symbol. A space bandit appears on the board and rams the birds one by one. All defeated birds disappear, and the board is cleared. If the bandit wins, it takes all the symbols on the screen and pays out the full reward.
Corner Bombs symbols are activated by collecting gems of the corresponding color. They expand the initial 6×6 grid to 8×8 and create portals. Through these portals, the birds can travel further and collect more gems, thus increasing the amount and frequency of wins.
Activates when there are no more collectible symbols on the screen, but the game can still continue. Triggers the explosion of one or more Corner Bombs to clear the board and add new symbols. This is a chance to win extra prizes in a single spin.
By collecting 3 Bonus symbols on the game board, you trigger a game with 5 free spins. You can then reactivate this feature an unlimited number of times and form combinations with the Bonus symbols.
A unique feature of the bonus game is that all upgrades, expansions, and progress are saved between games. The bonus game can trigger Corner Bombs, Spacecorn, Black Hole, and other features.
Activated as soon as the Super Bonus symbol appears. You get 8 free spins and an expanded 8×8 grid at the start. The main feature of this round is that all the slot machine’s features are activated much more frequently and are also more generous. You’ll benefit from more frequent upgrades, more Spacecorn symbols, as well as enhanced Transformation and Bomb features.
You can instantly activate various functions by paying a certain number of bets:
The Pirots 4 slot machine is characterized by high volatility. This means that wins in the base game are rather rare, but the payouts can be substantial. This is particularly attractive to high rollers willing to take risks for big wins.
The game’s return to player (RTP) rate is 94%, which is also low. However, in the long run, the game can be profitable, mainly due to the large number of bonuses and random features.
The Pirots 4 slot machine is a successful sequel to the famous series. If you’re a fan, feel free to try it for free on our site. Besides the improved graphics, you’ll discover many new mechanics. Numerous random features enhance the unpredictability and make the game even more dynamic. The developer has not only succeeded in extending the series but has also significantly improved the slot machine, thus increasing your chances of winning.
