To Play the Game:

  • You must first select your Line Bet.

Play for the highest Line Bet if you wish to play for the maximum Jackpot award. The Jackpot award will be explained in greater detail later in this text.
  • The number of paylines is always fixed at 50 for Streak of Luck slot.  This cannot be adjusted. Therefore, the Total Bet for each spin will be calculated as 50 x Line Bet.
  • When you have selected your Line Bet, press the Spin button to start the Streak of Luck slot game. When the reels are in the process of spinning, you can speed up the process and go straight to the result by clicking on Stop, which appears in place of the Spin button.
  • You can also spin the reels automatically using the Auto Play function. This allows you to set a predetermined number of spins to be played through consecutively without your input. Select the Auto Play button and choose from 10, 25, 50 or 99 Auto Spins. The slot will spin the reels automatically, unless you pres Stop or a Bonus Feature is awarded.
  • For more rapid play you can select Turbo Mode. This skips over the animations and allows for faster play.
  • When the reels have come to rest after a spin, any winning combinations will be clearly highlighted on screen. The total value of the win will be displayed in the Win Box, located in the bottom centre of the screen.
  • All possible winning combinations are displayed in the Paytable, which can be accessed by clicking on the Info button on the bottom right of the screen. When calculating the value of a Line Win (matching symbols on a payline), take the corresponding figure from the Paytable and multiply by the Line Bet.  For a Scatter Win, multiply the figure in the Paytable by the Total Bet.
  • Only the highest win is paid on each individual payline. Multiple wins can regularly occur, although these must be on different paylines.
  • Landing consecutive wins can lead to special bonus awards. These are highlighted on the Jackpot Meter on the right hand side of the reels. This will be explained in greater detail later in this text.

Info Page:

The informational pages for Streak of Luck slot can be accessed by selecting the Info button, which is located on the bottom left of the screen.  You flip between the different Info Pages by using the arrows on the bottom left of the screen. If you want to exit and return to the reels select the Back button from the bottom right of the screen.  There is also a Launch Tutorial button on the bottom right of the screen; selecting this will open up a tutorial screen describing some of the special features of Streak of Luck. The Info Pages are as follows:

Paytable: displays all the values of winning combinations, as well as basic information on the Bonus Features.

Dice Bonus: gives information on the rules and rewards of the Dice Bonus.

Lucky Free Games: provides information on the rules and rewards of the Lucky Free Games Feature.

Lucky Jackpot: lists information concerning the Lucky Jackpot award.

Paylines: displays a graphic showing all 50 paylines as they would appear on the reels.


Paylines are the shaped directions that matching symbols must follow across the reels to register as Line Wins. There are 50 fixed paylines in Streak of Luck slot. These cannot be adjusted.

Please be aware, there is a clear difference between the Line Bet and the Total Bet. The former is the wager on each individual payline, whereas the latter is the bet on all paylines, i.e. Line Bet x 50.

About Payouts:

All the potential payouts for the game are displayed in the Paytable. With regards to Line Wins, multiply the corresponding figure by the Line Bet. For Scatter Wins, multiply by the Total Bet.

Only the highest win is paid one each individual payline. Multiple wins can occur regularly, but these must be on different paylines. Multiple Line Wins or added together – alongside any Scatter Wins – and paid as a Total Win.

For a Line Win to occur, it must begin on reel 1 and form itself in an unbroken chain on a payline moving left to right across the reels.

Wild Symbol:

The Wild Symbol – represented by the Lucky Lady – can substitute for all other standard symbols in Line Wins. This symbol does not stand in for the Bonus or Scatter Symbols.

A group of Wild Symbols can also form their own unique Line Win. When this occurs it is possible to have coinciding wins on the same payline, i.e. the Line Win featuring only Wild Symbols and a Line Win using the Wild Symbols and other standard symbols; in this situation you will be paid for whichever combination has the highest value.

The Wild Symbol can appear stacked (covering an entire reel) or it can appear covering one reel position only.

Scatter Symbol:

The Scatter Symbol – represented by the Luck Playing Cards – does not need to appear on any particular payline. If you land three or more Scatter Symbols you will be awarded a cash win. This is calculated by multiplying the figure displayed in the Paytable by the Total Bet.

Bonus Symbol:

The Bonus Symbol – represent by the Bonus Dice – does not have a monetary value. Instead, if you land the Bonus Symbol anywhere on reels 1, 3 and 5 after a spin the Dice Bonus will be awarded. The Bonus Symbol appears on reels 1, 3 and 5 only.

Dice Bonus:

When the Bonus Symbol has landed on reels 1, 3 and 5 you will be awarded the Dice Bonus. When this happens:

  • Press Click to Start to begin the Bonus.
  • You will be taken to a new screen where you will be prompted to roll a pair of dice.
  • When you roll the dice you will win a multiplier of the Total Bet.  The Bonus will pay between 2 and 12 x the Total Bet for each roll. The Total Bet remains the same as the triggering spin. This cannot be adjusted.
  • Initially you are awarded three rolls of the dice.
  • There are certain special outcomes that can boost your winnings: rolling a Double will give you an extra turn. Rolling two ‘Lucky Sevens’ during the Bonus will pay 20x the Total Bet. Rolling Lucky Sevens three times during the Bonus you will win 200x the Total Bet. You can win up to six rolls of the dice during the Bonus.  When you roll three Lucky Sevens, the second award for Lucky Sevens is discarded.
  • If the Dice Bonus is awarded during Free Games all wins will be doubled.
  • When all rolls have been played a summary screen will appear informing you of your Total win for the Dice Bonus.
  • Press Continue to return to the reels.

Wins Counter:

The Wins Counter is displayed on the right hand side of the screen at all times. With each consecutive winning spin you move your way up the Wins Counter. It will take four consecutive winning spins to unlock the first prize on the Wins Counter. If the fifth spin is a winning spin you will move another step up the Wins Counter and so on until you have not made a winning spin. When this occurs you will be awarded the Bonus from the last stage of the Wins Counter.

The Wins Counter awards are summarised in the table below:

Consecutive winning spins:




5 Free Games with 0-2 Random Wilds.



10 Free Games with 0-2 Random Wilds



15 Free Games with 0-2 Random Wilds



20 Free Games with 0-2 Random Wilds



45 Free Games with 0-2 Random Wilds



60 Free Games with 0-3 Random Wilds



Lucky Jackpot


Wins accrued in the Free Games Bonus do not add to the Wins Counter. All wins from the Dice Bonus and base game will add to the Wins Counter.

Please note: The Wins Counter records consecutive wins for each Line Bet value, thus when you adjust the Line Bet the Wins Counter will return to zero. If you readjust the Line Bet to a value where you had a winning streak the Wins Counter will resume at that level once more.

Lucky Free Games:

When you achieve between four and nine consecutive winning spins you will be awarded Free Games. The amount of Free Games won and special enhancements awarded depend on the number of consecutive winning spins, as displayed in the table above. When Free Games are awarded:

  • Press Click to Start.
  • Free Games will play through automatically.
  • A box on the top of the screen will show the remaining Free Games.
  • The total current win for Free Games is displayed in the Win Field. All wins, including the Dice Bonus, are doubled during Free Spins.
  • A number of random Wild Symbols can be added to the reels during every spin. The amount of Wild Symbols added depends on the Wins Counter level that triggered the Free Games.
  • The Line Bet for Free Games is the same as that of the triggering spin. This cannot be adjusted.
  • Free Games cannot be retriggered.
  • When you have played through all Free Games a summary screen will appear detailing your Total Win.
  • Press Continue to return to the reels.

Lucky Jackpot:  

At the very top of the Wins Counter you can view the Jackpot. This will be awarded to you if you achieve ten consecutive winning spins in the base game. The size of the Jackpot will increase or decrease depending on the size of your Line Bet.

The rules around the Jackpot are the same as for the Free Games, in that only wins achieved during the base game or Dice Bonus count towards the Wins Counter.

If you change the size of your Line Bet, the Wins Counter will reset to zero, or to the previous level if you have already played at the same Line Bet.

If you win the Jackpot the Wins Counter will reset to zero once more.

The Streak of Luck Jackpot is a progressive fund. This means that it is primarily funded by taking a small percentage of each player’s wagers. The idea is that the progressive jackpot will grow and grow until it is won by a single player. The casino will provide a base amount (called a seed) to ensure that the fund is relatively large, even if won twice in quick succession. It is awarded and funded as follows:

Seed (base amount provided by casino) – dependent on the Line Bet (larger Line Bet = larger seed fund)

Contribution Rate (percentage of each player’s bets used to fund Jackpot) – 1.40%.

Win Condition (result needed to win Jackpot) – 10 consecutive winning spins at the same Line Bet in the base game.

Win Requirements (how to be eligible to win Jackpot) – no special requirements, simply play Streak of Luck slot.

Return to Player:

The RTP (Return to Player) for Streak of Luck slot at William Hill Casino is 94.99%. This is based on a theoretical long term average and not a guarantee for a single session.
