How To Play

The player chooses their bet amount using the + and - buttons. For details on win payouts see the game paytable.

To play the game, the player presses the SPIN BUTTON. If playing on PC and if enabled in the game options menu, the space bar can also be used to spin the reels.

Winning symbols are raised over the reels when the spin stops.

Wins pay from left to right.

Simultaneous or coinciding wins on different ways are added.


GigaBlox are massive symbols on enlarged reels.

GigaBlox symbols can be up to 5x5 in size. GigaBlox symbols will be split into normal 1x1 symbols for the purpose of win calculation.

Money Ways

Fish symbols can land in view on any reel. Fish symbols land with cash prizes attached to them, and can win as per any other normal way win, on adjacent reels from left to right. When a win occurs, any Fish symbols involved in the win will award the total prize shown on the symbol.

Fish symbols can appear on GigaBlox reels. GigaBlox Fish symbols will split into 1x1 Fish symbols, all with the same cash prize. The total displayed on the GigaBlox Fish before splitting is the total of all the 1x1 cash prizes for all symbols that form the GigaBlox. Only the 1x1 Fish symbols that land in the reel area and are involved in a Ways win will be awarded.



The Wild symbol substitutes for every symbol apart from scatters.

Wilds have no payout and can appear on any reel.

Respin Scatter

Landing 3 or more Respin Scatters in view on the reels triggers the Respin bonus.

Respin Scatters on GigaBlox reels will not appear as large symbols but will appear as adjacent 1x1 symbols across the GigaBlox reel. Each 1x1 Respin Scatter across a GigaBlox reel will count as a separate scatter.


Seaweed does not award wins.

Big Game Fish

Big Game Fish can land as GigaBlox symbols:

  • The BIG Big Game Fish will land as a 2x2 GigaBlox symbol.
  • The SUPER Big Game Fish will land as a 3x3 GigaBlox symbol.
  • The MEGA Big Game Fish will land as a 4x4 GigaBlox symbol.
  • The ULTRA Big Game Fish will land as a 5x5 GigaBlox symbol.

The total values of these Big Game Fish can be found next to the reels, which are the total value of all of the component 1x1 symbols after the Big Game Fish GigaBlox symbol splits. Any of the 1x1 symbols that are involved in a Ways win will award an equal portion of the full Big Game Fish prize as part of that win.

Giant Squid Features

The Giant Squid may randomly appear on any spin in the base game and trigger one of the following features:

Squid Shuffle Feature

Seaweed will reveal symbols, guaranteeing a win.

Squid Shuffle Feature

The reels will shuffle into a new order creating a win.

Squid Swap Feature

Swaps symbols to create wins on the reels.

Giga Summon Feature

A large GigaBlox reel will be summoned, which will contain symbols sized 4x4 or larger.

Fishing Respins Bonus

Landing 3 or more Respin Scatters in view on the reels triggers the Fishing Respin bonus.

Each reel that a scatter lands on will be open; all other reels will be closed.

The top and bottom symbol positions on each reel will also be closed at the beginning of the bonus.

Any Fish symbols that land on the triggering spin will be locked on the reels, regardless of whether they land on a reel that is open or closed. If they land in the top or bottom positions, they will be moved to another position on the same reel.

All symbol positions will spin, and any new Fish symbols that land on open reels will be locked in place. Fish symbols that land on closed reels will not be locked.

GigaBlox symbols up to 5x5 in size can spin into view. These will then split into 1x1 symbols - any of these 1x1 symbols that are on open reels in positions that do not already have a symbol locked in place will be locked as normal.

If a Respin scatter lands on a closed reel, that reel will be opened for subsequent respins. Respin scatters cannot land on already open reels.

The player will have 3 respins. If a new Fish symbol is locked in place or a Respin scatter opens up a closed reel on a respin, the number of remaining respins will be reset to 3. When the player runs out of respins, the bonus is over, and the cash prizes from all Fish symbols that were locked to open reels will be awarded.

Shark Feature

If all open positions on an open reel are completely filled with locked Fish symbols, a shark will swim up that reel and collect the cash prizes from all of the Fish symbols. The total prize will be multiplied by 2x and held in a single position on the reel; the other reel positions will then be reopened for new Fish symbols to land in.

The first time that this occurs on a reel, this will open the top and bottom positions on the reel.

These positions have a symbol multiplier attached to them. Locking a Fish symbol into one of these positions will multiply its cash prize by this multiplier. This multiplier will only be applied to the first symbol that is locked in this position.

How To Calculate A Win With 46656 Ways

If any of the reels contain more than 1 instance of a symbol, the win will be multiplied.

Multiply the number of symbols on each of the reels to get the final payout multiplier.

For example, if the first reel contains 2 symbols, second reel 3 symbols and third reel 2 symbols, the paytable value is multiplied by 2 x 3 x 2 = 12.
