Paylines

Maximum Potential Win Per This Jurisdiction!

Be aware that there is a maximum potential win allowed in the jurisdiction you are currently playing. This means that, even though the game may display higher win amounts, your balance will be credited only for the maximum potential win cap in your jurisdiction.

Max Win Probability

The probability of the maximum win displayed in this game refers to the sum of winnings of the highest possible symbol values, across all possible win criteria – either as a single game round or collectively as part of a feature. This may, or may not, include additional winnings obtained through extra win multiplying possibilities within the game. Higher winnings are also possible at a lower probability.

Quick Start

Game starts by setting a selected bet amount and by pressing the Spin button. Round ends when reels stop and there are no wins, or after the win presentation if there are wins.

Turbo Mode (Where Available)

Turbo mode (where available) speeds up reels spinning animation when enabled. This option does not influence the game round result but only visual presentation.

Game Menu

Game menu contains options and settings that control some of the game features:

• History – Displays previous rounds from the current session
• Close Game – Closes the game client
• Sound – Controls the sound effects in the game (on/off)
• Music – Controls the music in the game (on/off)
• Turbo mode (where available) – Controls the Turbo mode feature (on/off)

Game is paused while the menu is visible and can be closed by pressing the Close button or anywhere on the screen.

Bet Selection

Game starts with a default bet amount set for the game. Player can change the bet amount by either:

• Using Up and Down arrow buttons next to the Bet Amount
• Pressing the Bet amount where the Bet Amount selector will open up

The bet amount cannot be changed during a game round, and if there is a win presentation happening, changing the bet amount will reset the presentation.

Malfunction

A malfunction of the game voids all pays. In case the game round is interrupted, it can be restored by simply starting the game again. If it is not restored, the round is voided within the jurisdictional requirements or operator’s policy and their terms and conditions.
