Highway Kings

5-ReelsLandscape AND Portrait Mode

5 Reel Muti-Line Slots

When you play Highway Kings Slot online the aim is to match symbols on active paylines across the game reels. In this

To Play the Game:

  • Start by choosing the value of your coin. Do this by using the +/- button on the bottom left of the screen.
  • When you have selected your coin value you must select the number of coins you wish to play. Do this by pressing the Bet One button on the bottom centre of the screen. Each time you press this button another coin will be added to the Line Bet. Keep pressing to reset to One Coin.
  • The Number of Lines is adjusted by pressing the Bet One button. There is a maximum of 9 paylines. The Total Bet for the Game will be calculated as Number of Lines x the Line Bet.  
  • When you have settled on your Total Bet select the Spin Button to start the Highway Kings slot.
  • You can also spin the reels by choosing the Bet Max button. This will spin the reels at the maximum number of lines for your bet.
  • Wins pay from left to right and right to left. If a winning spin is achieved it will be highlighted on the game reels. All winning symbol combinations can be viewed by accessing the Paytable. Multiple wins (on different paylines) are added together and paid as a Total Win.


Paylines are the line shapes, or paths, that matching symbols must follow across the reels in order to form winning combinations. In Highway Kings (unlike many other online slots) the lines play from right to left as well as left to right.

The Paylines can be viewed by actively pressing the Bet One Button below the reels.

Please Note: only active paylines can register wins. The Scatter Symbol (which will be discussed in further detail below) is an exception to this rule.

About the Winning Tables:

All information on the winning symbol combinations are displayed on the Paytable. You can load the Paytable by pressing the Button marked Pay-Table from the bottom left of the screen.

The Paytable will display the amounts paid for matching symbols on paylines. In Highway Kings the number of matching symbols is referred to as Hits. The paytable will display a chart with ‘X’, ‘XX’. ‘XXX’, ‘XXXX’ and ‘XXXXX’ referring to the number of matched symbols (Hits) on a payline.

To work out the value of the cash amount for a winning combination, simply look at the corresponding number of Hits on the chart. For example, if you landed four Yellow Truck Symbols on an active payline, then you would check ‘XXXX’ under the Yellow Truck Symbol on the Paytable. This will read as 250. To get the Total Win, you must multiply 250 (in this example) by the Line Bet.

Multiple Wins are added together and paid as Total Win. As this slot pays from left to right and right to left, multiple wins are common. However, you will only be paid once for Five of a Kind.

Please Note: There is a difference between the Line Bet and the Total Bet. The Line Bet is the amount wagered on a single line, whereas the Total Bet is the Line Bet x the Number of Lines. The Total Bet is the amount taken from your balance to spin the reels. For the purpose of payouts as displayed on the Paytable, all Line Wins are multiplied by the Line Bet.

Scatter Symbol:

The Scatter Symbol – represented by the Exhaust Pipe Symbol – does not need to appear on any payline to be considered active. The Scatter Symbols must land on consecutive reels from left to right or right to left, starting from reel 1 or reel 5. Landing two or more in this fashion will pay a cash award. The payout for Scatter Symbols is displayed in the Paytable. All payouts for Scatter Wins are multiplied by the Total Bet.

Dollar Ball:

When you play Highway Kings online casino slot at William Hill, you will also have the opportunity to play a Lottery style side bet game called Dollar Ball. The aim of the game is to pick 5 numbers from a set of 49, if you match 5 balls you win the Progressive Jackpot. There are cash awards for matching any of 1 through 5 balls. To play Dollar Ball:

  • Click the Enable Button underneath the Dollar Ball Box, which is located on the top right-hand corner of the Highway Kings reels.
  • A lotto style strip containing the numbers 1-49 will be displayed. Select 5 numbers by clicking on them. Alternatively you can use the Random Pick option to have 5 numbers selected for you. To change your numbers simply click on a chosen number and start again. Once you have made your selection, press the Activate button to close the Dollar Ball Screen and return to the main game.
  • Your selected numbers will displayed at the top of the screen. When you spin the reels of the base game, the Dollar Ball game will commence and the winning numbers will appear underneath your selection when the reels come to rest. Any matching balls will be highlighted and the cash prizeawarded to you.
  • If you choose to spin again, the Dollar Ball game will also launch again until you press the Disable button.

Please Note: All the information for the Dollar Ball payouts can be found by accessing the Paytable. When the Paytable screen is open, click the button labelled Dollar Ball Paytable from the top of the screen.

Please Note: The outcome of the Dollar Ball side bet game is independent from the main Highway Kings slot game. You do not need to have a winning spin win in the main game to win with Dollar Ball.


As Highway Kings online slot features a Progressive Jackpot game (Dollar Ball) certain facts about how these jackpots work should be available to the player.

A Progressive Jackpot is funded by taking a small percentage of each player’s wagers to create a pot. This can be built up by a large selection of player’s across a wide range of different games and different online casinos. The Jackpot fund gets bigger and bigger until it is won. Each online casino will provide a base amount to ensure that if the Jackpot is won twice in quick succession the cash amount awarded will still be relatively large. The initial money provided by the casino is called a Seed Fund.

Please Note:

  • In some circumstances you must make a certain bet to be eligible for the jackpot award.
  • In the event of becoming disconnected from the game due to loss of internet signal etc. you will be returned to the same point in the game when you reconnect and log in again. Thus, when you continue your spin etc. the Progressive award and all bets will remain the same.
  • If the Jackpot is removed by the casino, i.e. they are removing or changing the game, they are obliged to inform all players.

The Progressive Jackpot for Highway Kings (Dollar Ball) works as follows:

Seed (How much the casino provides for the base amount) – 10,000 x bet.

Contribution Rate (the percentage amount from each bet paid into progressive fund) – 10%.

Win Condition (how to win the jackpot) – match 5 winning balls in the Dollar Ball game.

Win requirements (how to be eligible to win the jackpot) – enable the Dollar Ball side bet game.

How to play casino games

Here's a rundown of some of our most popular online casino games, including how to play them, and which offers the highest payouts.

Online slots

Online slots are played more than any other online casino games. They’re relatively simple to play, which makes them a great option for beginners. Slots can also offer large payouts, particularly for a jackpot win.

Playing slots online is very straightforward. The simplest form of online slots are three-reel slots, which are based on the traditional fruit machines you may have seen in arcades. In these slots, you’ll see three columns and three rows of symbols, with the middle row being the payline. You place your bet and spin the reel, and if you get a winning combination, you win the amount stated on the paytable.

There are many other kinds of slots online available at William Hill Canada, such as five-reel slots and video slots, but they essentially work in the same way. While the odds of winning at slots are slimmer than other online casino games, they do allow you to play with small stakes on a wide variety of slots. Slots with a jackpot offer a larger prize pool, so let’s have a look at those next.

Jackpot slots

The main difference between regular online slots and jackpot slots is that the former have a lower maximum payout. With jackpot slots, however, there are larger top prizes, sometimes offering up to a seven-digit win on just a single spin.

While 'jackpot' can refer to a fixed huge cash prize awarded during jackpot games, the term is also used to describe progressive slot games. For fixed jackpot slots the size of the jackpot is, well, a fixed amount. With a progressive slot, the size of the jackpot increases each time a player places a bet on the game. Progressive jackpot slots are a great way to add to your online gambling experience. These games can offer some of the most exciting experiences of all casino games, as they provide you with the chance to win the biggest payouts you'll find online.

Online roulette

Online roulette games consist of a wheel with spaces that are either red or black and are numbered from 1-36. This popular game is easy to learn and even easier to play. All you need to do is predict where the ball will land and place your bet. The roulette wheel then spins, and if it lands on where you placed your bet, you win.

You may think that only one variant of roulette exists in online casinos, as this is typically the case at real-world casinos. However, at William Hill Canada, you’ll find multiple variants available, including a European version with one zero, and an American version with two. You’ll also find a French version that offers slightly improved odds if you bet on an even-money proposition.

Online blackjack

To win at online blackjack, you need a higher number than the dealer without exceeding 21. You are dealt two cards and can ask for another card as many times as you want before you reach 21.

One of the great things about playing online blackjack is the number of variants available. At a real-world casino, you’re restricted to just one or two games, but you'll find more here at William Hill Canada, including Blackjack Scratch, Royale Blackjack, and Blackjack Super 21.

Live casino games online

This is where online casino technology really comes into its own. Some players enjoy the thrills provided by a real-life casino but also enjoy the convenience of playing online. Live casino offers the ultimate experience to these players. The only difference between playing live casino at home and playing at a land-based casino is that with the former, the action is live-streamed to your device.

You’ll be playing at real tables, with real cards, and with real croupiers dealing your cards or spinning the wheel. Depending on the game, you'll also be playing with other players from all over the globe. With the ability to enjoy live chat with both players and the dealer, live casino offers a fantastic opportunity to enjoy an immersive experience while playing your favourite casino games online.

Enjoy free online casino games with casino bonuses

An online casino bonus is a great way to boost your balance with extra funds and make playing your favourite online slots even more fun. Casino bonuses come in a number of different forms and are applicable to a variety of online casino games.

Almost all casinos bonuses are subject to their own terms and conditions, but what you get back is certainly worth it. If you look at our current bonuses, you’ll see our welcome offer, along with any other offers we may have available. There isn’t a one-size-fits-all bonus, so just make sure to keep your eye on our bonus page in order to enjoy our selection of games the fullest.
