Game Features

Collection Feature

The Collection symbol is active during the base game on reel 6.

Tuna symbols have attached stake multipliers (x0.5, x1, x1.5, x2, x2.5, x3, x4, x5, x7, x10, x20, x25, x50, x75, x100).

The Collection symbol collects the multipliers from all Tuna symbols on the reels.

Lock and Spin Feature

Lock and Spin feature is triggered by 3 Boat symbols in view.

Tuna symbols lock on the reels until the end of the feature.

Feature starts with 3 re-spins and each time a symbol lands on the reel, the re-spins counter resets to 3.

When no re-spins are left or a full board is filled with Tuna symbols, all multipliers are collected from Tuna (x0.5, x1, x1.5, x2, x2.5, x3, x4, x5, x7, x10, x20, x25, x50, x75, x100) and the feature ends.

Lock and Spin feature starts after clicking the “Start” button on the Lock and Spin feature pop-up or after timeout.

Increase Feature Chance Mode

Increase Feature Chance mode doubles the stake.

The Collection symbol can land on all reels during this mode and Tuna symbols on the reels stick for the next spin.

The state of symbols on the reels is saved for each stake in Increase Feature Chance mode and is not carried over to other stakes.

Feature Respin™

Feature Respin™ is available after Lock and Spin feature.

It gives a choice to take the winnings from Lock and Spin or to replay the feature. In case of choosing replay, winnings from Lock and Spin are burned.

Feature Respin™ is available after Lock and Spin and can be played only once.

The best strategy is to replay Lock and Spin when the win amount in Lock and Spin is less or equal than:

  • For base game: x58.40 stake
  • For Increase Feature Chance: x46.50 stake

Otherwise the best strategy is to take the win.

Choosing the best strategy does not guarantee that it will award a higher return.

If no selection is made, then the best strategy decision will be made after timeout.

Gamble

Enter Gamble feature via “Gamble” button after any winnings awarded during the game. Choose a colour or suit to play the Gamble feature.

A card is dealt. Each card is drawn from a new 52 card deck. The gamble amount is doubled if the correct colour is chosen or quadrupled if the correct suit is chosen. If incorrect, the gamble is lost.

Press the Collect button to exit the Gamble feature.

You can gamble up to 5 times or until the take win amount is greater than £250,000.00.

No more than £250,000.00 can be won from the Gamble feature.

The Gamble feature is not available when the game winnings are greater than £125,000.00.

The RTP is shown in-game.

The outcome of each gamble is random and is unaffected by previous results.
