Pirots 4 RTP and Wagering

Pirots 4 - RTP and Wagering

In this fourth Pirots game, the action focuses on a 6x6 grid filled with gems of different colours. There are no paylines. Instead, the four Pirots move across the grid collecting gems that match their own colour. 

Bonus symbols can appear on the grid, too. Any gem or bonus symbols collected vanish, and the rest drop to take their place. These cascades continue until none of the Pirots can move to collect gems as usual. We will explain how bonus symbols affect the slot game later in our Pirots 4 review.

Pirots 4 Symbols and Audio & Video Design

Like other Pirots slots, this game boasts fun graphics and slick animation. The space setting looks fantastic, with plenty of details to pick out.

Watching Pirots zip around the grid makes this feel more like a classic video game than a slot. It should suit players looking for a change from more traditional slots. 

As for the symbols, you will see varied designs. There are four different gems, and you can upgrade each one up to seven times. The higher the upgrade, the higher the payout. The Red Gem awards the top prize on the paytable: 30x your bet at level 7. 

Bonus symbols include Spacecorn, Transform, Black Hole, and Coins.

Pirots 4 Bonus Features

In this Pirots slot, you can trigger the following bonus features:

Wild Symbol

Four Wild symbols can substitute for all gems at their current payout level. 

Black Hole Symbol

Black Hole symbols absorb Pirots and symbols, then drop them in random positions. 

Coin Symbol

Coin symbols carry values of 5x - 1,000x your bet. Each time a Pirot collects a Coin symbol, the value shown on the symbol is awarded. The Max Win Coin symbol pays the remaining amount needed to achieve the maximum win.

Upgrade Symbol

The Silver Upgrade symbol boosts the payout level of one gem type by one, two, or three steps. Gold Upgrade symbols increase the payout level of all four gems by one, two, or three steps. 

Spacecorn Symbol

Spacecorn symbols fill empty positions when collected. This allows the Pirots to cross empty positions to reach other gems. 

Transform Symbol

Collected Transform symbols convert gems next to a Pirot to match the bird’s colour. They can transform random gems into feature symbols, too. 

Power Clash

If three or more Pirots are adjacent to one another, they trigger a Power Clash. They collide in one position and then fly off in different directions. 

Alien Invasion

Pirots 4 - Alien Invasion

If a bird collects an Alien Invasion symbol, the Space Bandit gathers symbols one column at a time. This can trigger features and space duels. 

If you win space duels, you will boost the Space Bandit spaceship multiplier. This multiplier boosts prizes won during the feature, but only if you beat the Space Bandit in a duel.

Space Station

Pirots can use space station sections around the grid to reach gems and feature symbols. 

Space Portals

Space Portals teleport Pirots if they can collect symbols on top of at least two portals. 

Corner Bombs

When Pirots collect symbols of matching colour on corner bombs, the explosives activate. These remove space station sections and can expand the grid up to an 8x8 layout. 

Lost in Space

Pirots 4 - Lost In Space

If the grid is cleared in the Spacecorn feature, the Lost in Space game triggers. This gives you three drops, but landing Coin symbols or bridges resets the counter. Lost in Space uses the maximum 8x8 grid layout. 

Bonus Game

Pirots 4 - Bonus Game

When a bird collects three Bonus symbols, the Free Drops Bonus Game triggers. You have five free drops, but each Bonus symbol collected awards one more. 

X-iter

The X-iter feature lets you trigger a bonus instantly for a price (3x - 500x your bet).

Pirots 4 Final Thoughts

There is a lot to like in this slot, whether you have played the others or not. The visuals, sound, and general presentation are excellent. And the Pirots’ energy and charm add to the game’s entertainment factor. 

One drawback is the below-average RTP of 94%. And slot newcomers may feel overwhelmed by the high number of features, too. But even with these little issues, Pirots 4 is another great entry in the series.
