The saga, which commenced in 2023 with the release of Pirots continued through a prehistoric theme park in Pirots 2, and then ventured into the Wild West in Pirots 3. Now, it embarks on an intergalactic quest. To summarize the backstory, the parrots were unable to enjoy their earned bounty after an alien monster emerged from a black hole and stole their treasure. Acting on impulse, they jumped in after it and found themselves floating in outer space near a mysterious station.
The Pirots series has solidified its place in the iGaming industry with three successful launches that resonated with players due to their distinct themes and impressive interconnected features. Like its predecessors, except for the Pirots X deviation, the gameplay centers around the innovative CollectR payout system alongside supportive features such as grid expansions, symbol upgrades, and instant prizes. As is typical, the action intensifies as symbols drop onto the grid, prompting the birds to search for their precious gems. Additionally, two exciting bonus games enhance the setup, offering remarkable prizes of up to 10,000x the bet. Within this review, readers can explore the Pirots 4 demo, allowing them to play for free and become familiar with its layout and features.
This review has been updated to incorporate recent additions made to the game within the months following its initial release, including two new worlds, Frozen Fury and Inferno, featuring new visuals and mechanics, which we shall detail in subsequent sections.
Pirots 4 is a video slot from ELK Studios featuring 6 reels, 6 rows, and a CollectR payout mechanism that requires bird symbols to gather adjacent gems of matching colors. Players can select their stake from a range of options, beginning at a minimum bet of 0.2 up to a maximum bet of 100. The game includes a default RTP of 94.00%, combined with medium-high volatility, and a maximum win capped at 10,000x the bet. The anticipated average base hit frequency is 25%.
The action of the Pirots 4 slot occurs in an unknown area of the universe where the birds were transported following their jump into the black hole. In the background, the endless blue of space is sprinkled with bright stars. Closer, asteroids drift by while a mysterious red planet, accompanied by a countdown clock, looms on the left. The playing grid is encased in a metallic contraption that resembles a space station.
This was the initial form of Pirots 4’s release, which shortly introduced an additional world after the countdown reached zero. This new realm, Frozen Fury, features an icebound environment with a new foe, the Yeti.
Another month later, the final world, Inferno, was added, introducing a conflict against Charlie in a mech suit and his fire minions on a planet engulfed in flames.
To achieve a win, any of the four birds must land beside a gem that matches its color. Upon doing so, the bird collects the symbol and any connected matching ones vertically or horizontally. Players can engage in this interstellar adventure from any modern device, including desktops, smartphones, or tablets.
The paytable includes 4 differently colored gems, each with 7 payout levels. The blue gem pays between 0.05x and 7.5x the bet. The green gem pays between 0.05x and 10x the bet. The purple gem ranges from 0.1x to 15x the bet, while the red gem pays between 0.1x and 30x the bet. Additionally, there are various special symbols such as Wilds, Coins, Spacecorn, and Black Hole, which will be explored further in the feature description section below.
What is the max win in the slot Pirots 4?
Players can win up to 10,000x the bet.
What features are available in the slot Pirots 4?
The features include Symbol Collection, Feature Symbols, Power Clash, Alien Invasion, Space Station & Portals, Lost in Space, Bonus Game & Super Bonus Game, Feature Buys (X-iter), Frozen Fury World, and Inferno World.
Each bird collects gems of its matching color and feature symbols that are directly adjacent vertically or horizontally. Each gem possesses 7 payout levels, which can be enhanced by collecting upgrade symbols that improve either one type or all types of gems by 1, 2, or 3 levels.
Feature symbols can appear naturally on the reels or can be generated by the collection meter, which tracks all collected gems and wild symbols during the current spin. Once the symbol collection meter is full, a feature will be saved; it is possible to store up to 3 features simultaneously by filling the meter three times. Once no more symbols can be collected, the meter releases the feature symbols onto the grid.
Bonus = awards a regular Bonus symbol.
Super Bonus = awards a Super Bonus symbol.
Wild = awards a Wild symbol that substitutes for any gems.
Coin = awards a payout displayed on the coin as a multiplier of the active bet. Players can also land a max win coin, which grants the game’s total max win of 10,000x the bet instantly.
Upgrade = upgrades one gem type.
Upgrade All = upgrades all gem types.
Transform = transforms a cluster of gems adjacent to the bird into its color.
Spacecorn = fills empty grid spaces with Spacecorn that allows birds to traverse through them once to access additional symbols.
Black Hole = absorbs all symbols and up to three birds, then releases them in random positions. Up to 3 birds can be discarded by this feature, leaving only the remaining birds’ gems available upon return.
Alien Invasion = triggers the respective feature.
The feature is activated whenever three or more birds align adjacent to one another. The birds engage in a battle, clearing all symbols in a 5×5 pattern around them, and fly off in random directions, collecting and activating any special symbols in their path. When two birds stand next to each other, they can perform a Switcheroo to swap their positions if it enables the collection of additional gems.
During this feature, the Space Bandit appears above the grid, moving between random columns and collecting gems and feature symbols, excluding Black Hole and Spacecorn. If it encounters a column with a bird, it will collect symbols only up to the bird’s position. Following this, the bird is sucked into the Space Bandit’s spaceship for a duel. If the Space Bandit wins, its multiplier increases by 1, and the defeated bird is removed from the game until the feature concludes. If the bird wins, the feature ends, and the total collected prize is awarded, multiplied by any potential multiplier. If all 4 birds are defeated, the Space Bandit collects all symbols from the remaining columns and awards its prize, followed by a random number of Coins being placed on the grid and the birds returning.
The space station is divided into 4 segments that can be destroyed. Whenever a bird collects a symbol from the corner position while the light matches its color, the bomb is activated. This activation can also occur during the Alien Invasion feature if the Space Bandit collects a gem from that position. After each explosion, the grid expands by a random number of rows and columns, up to a maximum of 8×8. Additionally, any remaining segments of the space station function as tunnels for birds. If there’s a symbol of a matching color at both the entrance and exit of the tunnel, the bird will traverse through it. There is also a chance that up to 2 feature symbols will be present inside and will be collected automatically. Once the grid reaches the 8×8 size, corners will be populated by portals through which birds can travel to other corners if matching symbols are present.
The Lost in Space bonus round is triggered when the entire game grid is cleared during the Spacecorn feature. This round plays out on an 8×8 grid and begins with 3 drops that refill upon each new symbol hit on the grid. Only coins, bridges, and blanks can appear. Each corner will accommodate one of the birds, and the objective is to connect clusters of coins to them so they can collect their values at the end of the feature.
Collecting 3 Bonus symbols during the same spin in the base game activates the bonus round, which grants 5 free drops. Throughout the round, the progress of the symbol collection meter, symbol upgrades, and grid expansion persist and do not reset between spins. During the bonus game, players receive an additional free spin for every bonus symbol collected. If at least one of the three bonus symbols collected during activation is a super bonus symbol, the super bonus game will commence. In the super bonus game, players start with an 8×8 reel setup, where all upgrade symbols enhance all gems.
As with most releases from ELK Studios, this game offers various options to instantly trigger features via the X-iter feature buy menu.
3x = Bonus Hunt, quadrupling the chances of triggering the Bonus Game.
25x = a guaranteed activation of the Alien Invasion feature.
50x = a guaranteed activation of the Lost in Space feature.
100x = a guaranteed activation of the regular Bonus Game.
500x = a guaranteed activation of the Super Bonus Game played on the maximum grid with upgrade symbols affecting all gem types.
In this icy realm, many features operate similarly to the original version but have some replacements. Alien Invasion, which previously showcased a vulture battling Pirots, is now Yeti Snack Time. Here, the ice creature doubles its multiplier each time it freezes a Pirot within its area, applying the multiplier to the prizes collected by the birds. Additionally, the Frozen Fury coin game features a similar twist, increasing any payouts from Pirots caught in the ice grip. Otherwise, it follows the same rules concerning coin collection and connecting them through ice bridges.
In this fiery world, where Pirots confront Charlie the mech, another unique set of visuals and features emerges, further diversifying the Pirots 4 experience. The main addition is the Fire Minions, which ignite adjacent birds, sending them on a fiery sprint that results in trails of gems and coins. Additionally, if any of the Pirots hit the “don’t press” button during the Inferno coin game, Charlie will set all four birds ablaze, plunging the gameplay into chaotic volatility.
The Pirots series is one that continually surprises, leaving players to wonder how each release can exceed the last. With every installment, the complexity yet consistency of mechanics remains impressive, offering a theme rich in thrilling elements. Introducing a new win system loaded with fantastic features in the first installment was already remarkable. Subsequent sequels built upon this foundation with even more innovative ideas. Just when one might think a trilogy would suffice for any online slot enthusiast, ELK Studios delivers a fourth installment brimming with fresh concepts. Given the series has explored popular settings like pirates, prehistory, and the Wild West, the switch to a space theme feels less surprising. However, it clearly demonstrates the team’s ambition to reimagine otherwise clichéd themes into unique experiences. They have once again achieved success, as evidenced by the striking quality of symbol design and the stunning effects accompanying the features. It represents a truly original and captivating showcase of the creators’ imagination and expertise.
Examining the game rules may quickly become overwhelming due to the multitude of intricate elements embedded in the setup. However, for players familiar with the series, the core gameplay remains instantly recognizable with the return of many special symbols like upgrades, transformers, coins, and traversable blanks. The usual position swapping and dramatic clashes between the birds are also present. So, what’s new? There is plenty. First, the Black Hole feature can finalize outcomes with as few as one bird remaining alongside all symbols on the grid in its color. Next, the Alien Invasion feature allows column-by-column symbol collection, with potential prize multipliers if enough birds are defeated by the Space Bandit. Another novelty is a new coin-based hold-and-win-style bonus that aims at clustering instant prizes and linking them with corner birds, evoking a sensation similar to the Jammin’ Jars 2 bonus. Lastly, the birds have devised new methods to reach different areas of the grid through exploded space station segments and teleports. We are genuinely impressed by ELK Studios’ unwavering commitment to improving their productions, even when previous releases have already astounded.
Pirots 4 delivers even more energy and features than its predecessors, returning with an array of engaging mechanics in a highly dynamic space setting.
