2 How to play
Spin the reels by pressing the spin button to try to get 3, 4, 5 or 6 matching symbols on a winning line.
Select the bet change button to increase or decrease the bet amount.
2.1 Automatic play
Press the autoplay button to see the options. You must select the number of autoplays and the loss limit to start the autoplay feature.
Your custom loss limit indicates the amount of money you're willing to lose before autoplay stops. For example, if you have a balance of £50 and set a loss limit of £20, autoplay will stop as soon as your balance drops below £30, even if you still have autoplay games remaining.
You can accept the suggested loss limit (which is your stake multiplied by the number of autoplays selected) or manually set a loss limit by pressing the custom loss limit button.
Select the "More" option in settings if you want to stop automatic betting when you exceed a certain amount of winnings.
Select the autoplay button during autoplays to stop them.
2.2 Turbo Mode
Activating Turbo mode speeds up the reel spin animation to increase the game's speed. This does not affect the game's outcome.
3 Rules of the game
All games are played with 50 winning lines.
Prizes can be won on any winning line.
Only the highest prize is paid for each winning combination.
All prizes are paid from left to right for adjacent reels, starting with the leftmost reel.
The winnings from the different lines played are added together.
Winnings will be added to your account immediately.
If you lose the game, you will lose the amount wagered.
The wild symbol substitutes for any symbol except the special bonus symbols.
It appears on the reels in the basic game and on reels 2, 3, 4 and 5 and in the free spins bonus.
During free spins, any wild symbols in view will be locked on the site until the bonus is completed.
4 Bonus
4.1 Bonus Activator
The bonus symbol appears on all reels in the base game.
If 3 or more bonus symbols appear, the Big Bonus begins.
The initial Big Bonus value will be determined by the Pick Me round.
With 3 bonus symbols, the Big Bonus value can be x20, x25, x30, x50 or x100.
With 4 bonus symbols, the Big Bonus value can be x25, x30, x50 or x100.
With 5 bonus symbols, the Big Bonus value can be x30, x50 or x100.
With 6 bonus symbols, the Big Bonus value can be x50 or x100.
4.2 Match 3 Choose Me Game
In the Big Bonus match 3 game, you will determine the value of the Big Bonus.
The game will change and display 6, 9, 12 or 15 identical squares depending on the number of bonus symbols used to activate the bonus.
Selecting these symbols one by one will reveal a Big Bonus gem.
Each gem will be added to the Big Bonus path. When you roll 3 matching gems, you'll start the bonus with the corresponding Big Bonus value and your current Big Bonus path.
4.3 Big Bonus Free Spins
The Big Bonus path accumulates from the Pick Me round.
The Big Bonus Booster power-up gems that appear on reel 6 are added to the track.
Completing the active segment of the path with Big Bonus Booster gems improves the Big Bonus value.
On roller 6, only the gems from the active segment of the trail will appear.
During free spins, any wild symbol that falls into view will be locked in place and will remain there until the free spins are over.
The free spins will continue until a prize equal to or greater than the value of the Big Bonus is won.
5 Additional Functions
5.1 Opening opportunity
The roll opportunity is automatically activated if the credit falls below the current game price, as long as it is greater than zero.
This gives the player the opportunity to wager their remaining credit in an attempt to win an additional spin on the current bet.
To play Chance of Spin, select the "PLAY" button to start moving the pointer across the meter.
You can also select the "NO, THANKS" button to exit the spin opportunity with the remaining credit.
If the pointer stops on the green segment, a spin is awarded on the current bet and the game is played automatically.
If the pointer stops on the red segment, the player loses any remaining credits and returns to the base game.
The red and green segments are proportional to the credit amount relative to the current bet. The probability of winning a spin is determined by this ratio.
5.2 Bonus Purchase
The bonus purchase mode can be activated by pressing the Bonus Buy button.
Buying a bonus gives direct access to the Big Bonus in exchange for a ##x bet.
When you buy the bonus, at least 3 cash symbols and one bonus symbol will be forced into view.
All winnings are multiplied by the base bet.
The average payout across multiple play cycles in Bonus Purchase mode is 94.50%.
5.3 Fortune Bet
The Fortune Bet mode can be activated by pressing the Fortune Bet button.
The spin button is used to play Fortune Bet.
During Fortune Bet, the bonus is awarded 50% more frequently.
The thresholds for big wins, Big Bonus value, start bet and prizes remain the same as for the base bet.
The average payout across several game cycles in Fortune Bet mode is 94.50%.
