Pirots 4 has two game modes: normal mode and bonus mode with free drops.

Pirots 4 has four collector bird symbols that can be moved around the game board. Each bird is associated with a gem of the same color.

Birds can collect gems of their own color and all feature symbols.

Birds collect symbols by moving towards symbols they can collect that are adjacent horizontally or vertically.

The paying symbols are gems, coins and Wild symbols.

Wins are generated when a bird moves and collects paying symbols.

Gems can be individually upgraded to higher pay levels, up to a maximum pay level of 7.

The birds continue collecting until they can no longer collect any more symbols. A bird can move several times before a symbol refill occurs. Collected symbols and activated feature symbols are removed from the game board. Afterward, the remaining symbols and birds move vertically to a resting position, and new symbols appear from above to fill the spaces. The feature continues as long as there is at least one bird left to move.

On the game board is a symbol collection meter. The meter counts the collected symbols. Only gems and Wild symbols collected by any of the four birds count. The symbol collection meter continues counting the collected symbols until the birds can collect more.

The Space Bandit does not contribute to the collection meter, which will be deactivated during the Alien Invasion feature. Birds cannot collect symbols during the Alien Invasion feature.

When the symbol collection meter is filled, a pending function symbol generation is added.

There may be up to three generations of function symbols pending. All pending generations of function symbols are granted at the same time.

Corner bombs are placed in each of the space station's interior corners. Each corner bomb is randomly assigned a bird color at the start of the round and at the beginning of each free drop during the bonus game.

If a bird collects a symbol of its own color on the corner bomb, the bomb is activated. A corner bomb explodes when the birds can no longer collect any more symbols. It eliminates all birds on the game board and all gems within a 3x3 area originating from the corner bomb. When it explodes, the corner bomb also eliminates the section of the space station it is next to. Corner bombs can expand the game board to a maximum of 8 rows by 8 columns. Symbols fall vertically until they reach a stable resting position, new symbols fall to fill the empty positions, and the birds return.

One feature symbol spawn is awarded before the corner bomb explodes as part of the first free drop in the bonus game or when the birds cannot collect any more symbols.

A function symbol generation converts a random amount of gems into random function symbols.

There are ten different types of feature symbols in Pirots 4: Bonus, Super Bonus, Wild, Coins, Upgrade, Upgrade All, Transformation, Space Popcorn, Black Hole, and Alien Invasion.

Collecting a boost symbol increases the payout level of gems of the same color as the bird that collected the boost symbol. The gem payout level increases by 1, 2, or 3 steps, up to a maximum payout level of 7.

Collecting an Upgrade All symbol upgrades all four gems at once. The gem payout level increases by 1, 2, or 3, up to a maximum payout level of 7.

The Alien Invasion feature is triggered when a bird collects an Alien Invasion symbol. The feature remains pending and is triggered when the birds can no longer collect any more symbols.

During the Alien Invasion feature, the Space Bandit collects symbols column by column in a random order.

The Space Bandit can collect any Gem, Bird, and Feature symbols, except for the Black Hole, Space Popcorn, and Transform symbols, which the Space Bandit will ignore. The Space Bandit activates Corner Bombs by collecting symbols above the Corner Bomb positions. During the Alien Invasion feature, the Corner Bomb explodes before a symbol reload.

Upon collecting a bird, the Space Bandit's collection is interrupted and a space duel begins.

If the Space Bandit wins the space duel, the ship's multiplier increases, and the defeated bird is removed from the game board for the duration of the feature. The Space Bandit then chooses a random column and continues collecting symbols. If the bird defeats the Space Bandit, the Alien Invasion feature ends, and the ship's multiplier is applied to the accumulated value before its payout.

During the Alien Invasion feature, the total value collected and the multiplier the Space Bandit has achieved accumulate and are displayed on the ship.

If the Space Bandit defeats all four birds, the Space Bandit collects the remaining symbols on the game board, and the ship's multiplier is applied to the accumulated value before its payout. A random number of coins are then placed on the game board, the feature ends, and the birds return.

If a transformation symbol is collected, the color of a group of gems transforms next to the bird to the same color as the bird that collected the transformation symbol. A random number of gems can also be converted into function symbols.

When a bird collects the Space Popcorn symbol, Space Popcorn is placed in the spaces on the board. The birds can then cross the spaces, once each, to reach additional symbols.

The Lost in Space coin game is triggered when the birds have collected all the symbols that can be collected on the game board during the Space Popcorn feature. The Lost in Space coin game is triggered immediately, and all potentially triggered features are now pending.

The Lost in Space coin game is not activated if the Space Popcorn feature is not on the game board when the birds have collected all the symbols that can be collected.

The Lost in Space coin-op game is played on an 8x8 board and begins with a bird in each corner. Three drops are awarded. The drop counter resets to 3 when one or more coins or bridge symbols land.

When there are no more coins left, the birds can begin collecting. Birds can only collect coins that are adjacent horizontally or vertically. Birds can use adjacent horizontally or vertically bridges to reach the coins they can collect. If two or more birds are connected by the same coins, the value collected from the bird can be collected by the next bird that collects the same coins.

When the Lost in Space coin game ends, the total collected value is paid, the birds return to the game, and the game round continues.

The second chance of the Charlie feature can be triggered randomly when the birds can't collect any more symbols. It triggers one, two, three, or four corner bombs. The bombs explode simultaneously, and the birds leave the game board. The remaining symbols then fall vertically until they reach a stable resting position, new symbols fall to fill the empty positions, and the birds return.

The space station surrounding the original game board has four sections and functions as a tunnel when at least one of the sections is destroyed by a corner bomb explosion. A bird can travel through the tunnel when it can collect the tunnel entrance and exit symbols. Each tunnel section can reveal up to two feature symbols, which the bird will collect as it passes through.

A space portal will become available in a corner when the game board has been expanded to its maximum size and the corner space station section has been removed. Birds can teleport between each other if there are symbols that can be collected on two or more space portals.

Collecting a Black Hole symbol triggers the Black Hole feature, which is activated when the birds can no longer collect any more symbols. The Black Hole feature absorbs all symbols and birds on the game board and then returns them to different positions on the game board. The Black Hole can eliminate one, two, or three birds. All gems that are the same color as an eliminated bird change to the color of one or more of the returning birds.

The Wild symbol substitutes for any gem at its current payout level. A bird cannot end a symbol collection on a Wild symbol. If the bird ends up on a Wild, it will move to an empty position.

A coin symbol collected pays its value multiplied by the currently active bet level. The MAX WIN coin instantly pays the remaining amount needed to reach the maximum win.

When two birds are adjacent and can't collect any more symbols, there's a random chance they'll perform a Switcheroo. If triggered, the birds will swap positions horizontally or vertically.

Two adjacent birds also have a random chance to trigger a Space Switcheroo. If triggered, one of the birds will move to the edge of the game board or to the next symbol it can collect in its path. Gems that the bird can't collect don't count toward the collection meter when removed.

The Power Struggle feature is triggered when three or more birds land vertically or horizontally adjacent to each other, and they cannot collect any more symbols. During the Lost in Space coin game, three or more birds landing horizontally or vertically adjacent to each other does not trigger the Power Struggle feature.

During the Power Struggle feature, birds collide at a symbol position, eliminating all gems within a 5x5 area originating from the collision symbol position. The birds fly diagonally, horizontally, or vertically from the collision position. Corner Bomb, Alien Invasion, Black Hole, Coin, Bonus, and Super Bonus symbols are automatically collected or triggered if they are in the bird's flight path. Gems are eliminated if they are in the bird's flight path, but do not count toward the symbol collection meter. Other feature symbols are not affected.

The free drops bonus game is triggered if the birds collect three bonus symbols during an active game round. Five free drops are awarded.

Bonus symbols collected in bonus mode will award an additional free drop to the bonus game.

The normal bonus game starts with the current number of active rows and columns.

The Super Bonus game is activated if one of the three bonus symbols collected is a Super Bonus symbol.

The super bonus game starts with 8 rows and 8 columns and the respective upgrade symbols improve all gems to the maximum.

The progress of the symbol collection meter and the gem payout level are maintained during the bonus game.

If an Alien Invasion feature, Corner Bomb, or Feature Symbol Generation is pending when the bonus game starts, these will be triggered as part of the first free drop.

 The free drops bonus game ends when there are no free drops left or when the win limit is reached.

 Winnings will be paid at the end of the bonus game.

 Bets cannot be changed during a current round of play.

 A game round will end immediately when the win limit is reached; any winnings accumulated up to that point will then be paid out.

 The theoretical payout (RTP) on Pirots 4 is 94.0%.

 The maximum total win in a game round is limited to 10,000 times the bet placed.

 If a malfunction occurs, all bets and prizes are void.
