Game Rules

Desert Treasure

5-Reel, 20-Line SlotPick Treasure Boxes in the Oasis Bonus Round

Take a spin on Desert Treasure online casino slot, which features Free Games, Scatter Wins, Wild Symbols and a Hot Bonus Game.  This casino game blends fun slot play with the chance of a big jackpot – up to 10000 times your Line Bet. Don’t forget players at William Hill Casino can also enter the Dollar Ball side bet game for the chance to win a massive Progressive Jackpot!

The basic aim when playing Desert Treasure online slot is to spin the reels in order to match symbols on active paylines. There are also Bonus Features that can add to your winnings in the game.

To Play the Game:

  • Begin by choosing the value of your coin. This can be done by using the +/- buttons on the box on the bottom right-hand corner of the screen.
  • Then choose the Line Bet by pressing the Bet per Line button on the bottom centre of the screen. Each time you click on this button another coin – at your selected value – will be added to the Line Bet. You can place a maximum of 10 coins at any value on the Line Bet. Keep pressing the Bet per Line button to rest the number of coins to 1.
  • Finally, choose the number of lines (paylines) you wish to play per spin. Do this by pressing the Lines button on the bottom of the screen. Actively pressing this button will display the paylines as they appear on the reels. You can also select lines by choosing from the numbers on the sides of the reels. Please be aware, if you select a number it will also activate all lines numerically below it. For example, choosing 16 will also active paylines 1 through 15 as well.
  • The Total Bet per spin is therefore calculated as Line Bet x Number of Lines. The Total Bet is the amount deducted from your balance for each spin on Desert Treasure slot.
  • When you have selected your coin size, lines and Line Bet, press the Spin button to start the game. You can also spin the reels by selecting the Bet Max button; this will spin the reels at the maximum number of lines (20) at your chosen Line Bet.
  • If a winning result is achieved with your spin it will be clearly highlighted on the reels. The amount won will be displayed in a box just below the bottom right of the game reels.  The winning combinations are displayed in the Paytable, which can be accessed by selecting the Info button from the bottom left of the screen. The Paytable also displays a small graphic at the bottom of the screen, which shows all the different paylines as they appear on the reels. To exit the Paytable select the Back button from the bottom left of the screen.
  • Only the highest win is paid on each payline. Multiple wins can occur on different paylines, these are added together (along with any Scatter Wins) and paid as a Total Win.


Paylines are the pathways that matching symbols must follow from left to right across the reels in order to achieve a Line Win. You can view the paylines as they appear on the reels by actively clicking the Lines button, or by opening the Paytable and viewing the paylines graphic.

Only active paylines can register Line Wins. Scatter Symbols do not need to appear on paylines to pay.

Please Note: there is a clear difference between the Line Bet and the Total Bet. The Line Bet is the amount of money wagered on each individual payline, i.e. coin value x number of coins wagered. The Total Bet is the accumulative amount wagered on all paylines, i.e. Line Bet x Total Bet. The Total Bet is the amount deducted from your balance to play a spin on Desert Treasure online slot.

About Payouts:

All the potential payouts for every winning combination are displayed in the Paytable. When calculating the win amount for a Line Win you must multiply the value displayed in the Paytable by the Line Bet. For example, landing 5 Camel Symbols on an active payline will pay 400 x Line Bet, if your Line Bet was 10 you would win 4000. For a Scatter Win multiply the value in the Paytable by the Total Bet. More details will be given on Scatter Wins in a section below.

All winning combinations (Line Wins) must occur in an unbroken chain of at least two consecutive symbols, beginning on reel 1.

The Wild Symbol – represented by the Cobra – substitutes for all other symbols, with the exception of the Bonus and Scatter Symbols, to help form winning combinations.  The Wild Symbol also has its own unique award for matching Wild Symbols only on a payline.

If multiple wins occur on the same payline you will be paid for the highest winning combination only. Multiple wins on different paylines are added together, along with any Scatter Wins, and awarded as a Total Win.

Scatter Symbol:

The Scatter Symbol, which is represented by the Desert Lady, does not need to land on any particular payline to be regarded as active.  If you land 2 or more Scatter Symbols anywhere on the reels you will be awarded a cash win. This win is calculated by multiplying the relevant value in the Paytable by the Total Bet amount.

If you land 3 or more Scatter Symbols anywhere on the reels the Free Games Bonus will be activated. In the Free Spins Bonus:

  • You will be awarded 10 Free Spins. All Line Wins and Scatter Wins are tripled.
  • The Free Spins will play through automatically. A box – located on the top left-hand corner of the screen – will display the amount of Free Spins remaining. This box will also display the Total Win as it accumulates throughout the Free Spins Bonus.
  • Free Spins can be retriggered in the same manner as the base game. Landing 3 or more Scatter Symbols will add 10 more Free Spins to your remaining total. There is no limit to the amount of extra Free Spins that you can win.
  • The Bonus can also be awarded during Free Spins in the same manner as the base game, although this is not subject to the 3 x multiplier.
  • All Line Bets and paylines are the same as the bet that triggered the Free Spins. This cannot be adjusted.
  • When all Free Spins have been played through you will automatically be returned to the base game. Your Total Win will be displayed on the top left-hand corner of the screen.

Bonus Symbol:

The Bonus Symbol – represented by the Desert Map with Compass – does not have a monetary value. Its purpose is to launch the Desert Treasure Bonus Game. If you land 3 or more Bonus Symbols on a payline – in the same way as a Line Win – the Bonus Game will be activated. In the Bonus Game:

  • You will be taken to a new screen, ‘The Hidden Oasis’, where you will see a range of Treasure Chests and Vases etc.
  • You will be prompted to select one of the gifts to reveal a cash win.
  • The number of ‘Picks’ you get depends on the number of Bonus Symbols matched in the triggering spin. 3 Bonus Symbols = 3 Picks, 4 Bonus Symbols = 4 Picks and 5 Bonus Symbols = 5 Picks.
  • Each Pick is guaranteed to reveal a cash win, which is a multiplier of the Line Bet.
  • When all Picks have been made you will be returned to the main game, with the Total Win displayed in the centre of the screen.

Dollar Ball:

When you play Desert Treasure online slot at William Hill Casino you can also enter a side bet Jackpot game called Dollar Ball. The outcome of the Dollar Ball Jackpot game has no bearing upon the outcome of Desert Treasure slot and vice versa.

Dollar Ball is a lottery style game where the aim is to match your numbers (choose 5 numbers between 1 and 49) to the numbers drawn. Matching 5 numbers will land the Progressive Jackpot, which is normally a very large sum of money.

To Play Dollar Ball:

  • The Dollar Ball Menu is located on the top right-hand side of your screen. Press Enable to open the Dollar Ball tool bar. You will be able to select your 5 numbers, or else choose the Random Pick option to have them randomly selected for you.
  • When you have selected your numbers press Activate. This will close the Dollar Ball Menu and confirm your selection. Your selections will be displayed along the top of the screen.
  • The next time you spin the reels in the main game (Desert Treasure) the Dollar Ball draw will take place. If you match just one number to the drawn numbers you will win a cash amount.
  • There is a separate Paytable menu for Dollar Ball located on the top of the Paytable of the main game.

Please note: when you spin the reels again, you will be automatically entered into the Dollar Ball game again – and the entry fee deducted from your balance – unless you press the Disable button.


When you play Dollar Ball alongside Desert Treasure you are playing for a Progressive Jackpot award. Therefore certain information should be made known to you:

A Progressive Jackpot is funded by taking a small percentage of each player’s bets. This can be across a range of games and different online casinos. The idea is that it grows and grows until it is won by a single player. The casino will provide a base amount – called a seed fund – to ensure that the Progressive Jackpot is still large, even if won twice in quick succession.

Please note:

  • In some situations you may have to make a specific bet to be eligible for the Jackpot Award – in this case it is simply play the Dollar Ball game.
  • The software is designed to remember your exact point in every game at the point of disconnection. Thus, if you lose connection to the internet etc. you will be able to play for the same prize fund in Dollar Ball on re-establishing a connection once more.
  • The casino is obliged to inform you if the jackpot fund is no longer available, i.e. the game has been discontinued.

The Dollar Ball Jackpot is awarded and funded as displayed in the table below:

Seed (the base fund provided by the casino) = 10,000 x bet size.

Contribution rate (percentage of each wager taken to fund jackpot) = 10%.

Win Condition (what is needed to land jackpot prize) = match 5 numbers.

Win requirement (how to be eligible for the jackpot) = enter the Dollar Ball game.


The following buttons appear on screen and can be used to control the game:

Bet Max – places the maximum of five coins on the bet.

Lines – activates one more payline.
