Pearl Harbour

The Pearl Harbour slot invites players on a thrilling adventure inspired by historical events, featuring engaging graphics, dynamic gameplay, and innovative mechanics that immerse users in a wartime narrative filled with suspense, missions, and action-packed spins.

Cluster Payout Reel Area

The game area is a dynamic 7x7 area where the central 3x3 area is active initially and the rest are blocked.

Cluster wins are achieved with five or more matching symbols that are adjacent horizontally and/or vertically inside the active area.

After a winning Cluster, symbols in the winning Cluster will be destroyed allowing new ones to drop in.

Multipliers on symbols in winning Clusters are always summed up together with possible round multiplier from previous xBombs before they are multiplied to the Cluster size payout value.

The following features will expand the active area:

xBomb explosions
Targets
Colossal symbols

Scatter

In the main game, the Scatter symbol can land on any reel, but it only counts if it is in the active reel area.

If a Scatter symbol gets split and a bonus mode is triggered, the multiplier value of the Scatter symbols will become a (x)-Multiplier in the first bonus multiplier addition.

Scatter symbols can only land 1 per reel.

xBomb Wild Multiplier

xBomb Wild blows away a maximum of 10 symbols surrounding it in the active area. xBombs will only blow up inside the active area.

If an xBomb is adjacent to the active area’s border it will move the active area 1 reel or row. If the xBomb is in the corner of the active area it will expand the active area 1 reel and 1 row.

If the xBomb gets split it will get a x2 multiplier on first split and then increase it with times 2 for each consecutive split.

Exploding xBombs will increase the win multiplier for the next avalanche with +1 or the (x)-Multiplier amount it has been split into.

All xBombs will explode before the next avalanche.

Scatters and transformed Wilds that are not part of a win Cluster will not be blown away.

Target

Target symbols land anywhere on the reels.

When a Target symbol lands, the active reel area will expand to make the Target symbol be part of the rectangular active reel area.

When a Target symbol has landed and becomes part of the active reel area it transforms into a Wild symbol.

xSplit

xSplit symbol comes in the shape of a samurai sword and splits all symbols in the direction of the sword’s handle.

xSplit symbols have initially either one or two swords that can point both horizontally and vertically, but only one direction per sword.

xSplit symbol only activates when inside the active reel area and the avalanche has stopped.

If an xSplit symbol gets split by another xSplit symbol it will get an additional sword pointing in a new direction.

If an xSplit symbol has 4 swords a new split will add a times 2 multiplier.

If an xSplit symbol has a multiplier when activated all symbols it splits get the xSplit’s multiplier or multiply their current multiplier with the xSplit’s multiplier.

Scatter symbols, Target symbols and xBombs get a times 2 multiplier when hit by an xSplit.

Consecutive xSplits on multiplied symbols double the multiplier value.

After the splitting, the xSplit symbol becomes a Wild symbol.

The Wild symbol gets a multiplier depending on how many swords it had and possible multiplier will multiply the sword multiplier value.

Colossal Symbol

When a Colossal symbol drops in, the active reel area will expand its rectangular area so that the Colossal symbol becomes a part of the active reel area.

Colossal symbols come in the size of 2x2 and 3x3 and can have a multiplier of x2 or x3 and are initially counted as 1 symbol in a possible Cluster.

If a 3x3 symbol is split, it first splits into 3 symbols either vertically or horizontally depending on where the split comes from.

Second xSplit will split the Colossal symbol in the other direction to a 3x3 symbol regardless of xSplit direction.

Third xSplit will split all 9 symbols in half to a total of 18 symbols.

Fourth xSplit will either give x2 multiplier to each symbol from the initial Colossal symbol or multiply each individual multiplier with 2.

For 2x2 Colossal symbols the same principles are applied.

Dogfight

3 Scatter symbols trigger Dogfight feature. Dogfight feature starts with 3 spins and plays inside of a fighter plane cockpit with an instrument panel of 18 dials.

The instrument dials all start spinning and can either land a (x)-multiplier, (+)-multiplier or nothing. Any multiplier that lands will reset the spin count to 3.

When multipliers land they are active until they have added their values to the round multiplier.

All active (+)-multipliers are first summed up then they multiply all (x)-multipliers before they add that amount to the round multiplier.

The active (x)-multipliers remain active until a (+)-multiplier lands.

If a bonus round ends with active (x)-multipliers they turn into (+)-multipliers and sum up their value and add that to the round multiplier and end the bonus round.

Dogfight Attack

Fill up a column of dials.
A Dogfight attack is initiated.
All multipliers in the column become active.
If the enemy plane is hit the active multipliers are summed up in the same way as a normal bonus spin.
If there are only (x)-multipliers in the column they are multiplied together and with 1 to get the sum to be added to the round multiplier.
If the enemy plane is missed nothing is added and next spin is initiated.
If the spin initiating the Dogfight only had (x)-multipliers those (x)-multipliers remain active for next spin.
Multiple Dogfights are done in sequence from left to right.

Kamikaze Attack

If all 18 instrument dials have been filled a Kamikaze Attack will launch after Dogfights are done.
A multiplier wheel with 8 possible Multipliers (x1, x2, x3, x5, x10, x15, x30, x50), including misses, will spin as aircraft is approaching a target ship.
If the ship gets hit, the multiplier from the wheel will multiply with the total round multiplier from the bonus round.

Tora! Tora! Tora!

4 Scatter symbols trigger Tora! Tora! Tora! feature. Tora! Tora! Tora! feature starts with 3 spins and plays inside of a fighter plane cockpit with an instrument panel of 18 different dials.

Game play and features from Dogfight are the same, but with the additions of Midway Pop and Bomb Drop.

Midway Pop

Midway Pop is activated when a Multiplier lands on a dial in the mid row.
The amount value pops up to the top row in the current column.
If no value exists there from before it will randomly get a (+)-multiplier or a (x)-multiplier independently of mid row multiplier type.
If a value already exists on the top row, the mid row amount is added to the existing value and multiplier type remains.

Bomb Drop

Bomb Drop is activated when a full row of instrument dials is filled.
A bomb hatch opens up, a ship gets locked in and a bomb is dropped.
If the ship gets hit, all (+)-multipliers of that row get added together and are multiplied with all (x)-multipliers of that row.
If there are only (x)-multipliers in the row they are multiplied together and with 1 to get the sum to be added to the round multiplier.
If the ship is missed nothing is added and next spin is initiated.
If the spin initiating the Bomb Drop only had (x)-Multipliers those (x)-Multipliers remain active.
Multiple Bomb Drops are done in sequence from top to bottom. Possible Dogfights are done before Bomb Drops initiate.

Banzai!

At a cost of an extra +50% on the base bet, the player is guaranteed one Scatter symbol in the middle of the active area, increasing the chances of entering Dogfight bonus by over 3 times.

At a cost of an extra +100% on the base bet, the player is guaranteed two Scatter symbols landing on the initial drop. This increases the chances of entering Tora! Tora! Tora! bonus by over 10 times.

The payout for each symbol is not affected meaning all winnings are based on base bet value.

Mission Accomplished!

The maximum potential payout of the game is 41127 times the base bet.

If the total win exceeds this amount the game round will end and 41127 times the base bet is awarded.

Cluster Payout

Winnings are calculated by multiplying the symbols Cluster size payout value with all active multipliers added together. Only the highest win per Cluster is paid.

Clusters are defined as adjacent symbols horizontally and vertically touching sides with each other.
