Online Casino Games - Rules Explained

Captain's Treasure

5-Reel, 9-Line SlotPaylines Pay Both Ways!

5 reel Multiline Slots

The objective of Captain’s Treasure online slot is to match symbols across active paylines in order to win cash amounts. This a traditional casino slot game that gives a nod to classic games like online blackjack and roulette. You can also enter a side game – Dollar Ball – that offers a huge Progressive Jackpot.

To play the game:

  • Start by selecting your bet per line. To do this use the +/- button on the left-hand side of the screen.
  • Choose the Number of Lines you wish to play. To do this press the Bet One button on the bottom of the screen. Each time you select the Bet One button another payline will be added to the game. A maximum of 9 paylines can be played in a single spin. Alternatively you can select the paylines by choosing one of the numbers on the side of the game reels. Please note: if you, for example, choose the number 8 from the side of the reels this will also activate paylines 1-7.

Click Spin when you have made your bet selections. You can also spin the reels by selecting the Bet Max button. This will play the maximum number of lines at your selected Line Bet.

Please Note:

  • When the reels have come to rest, any winning combinations will be highlighted on the reels and the winnings (if any) credited to your balance.
  • All the winning symbol combinations and their respective values are displayed in the Paytable. This can be accessed by the selecting the Paytable button from the bottom of the screen. Exit the Paytable information screen by pressing the Paytable button again.

Multiple wins will be added up and paid out as a total win.


Paylines are the lined paths that appear across the reels and on which matched symbols must fall in order to award a win. You can view the paylines by actively clicking the Bet One button. In the case of this game, paylines pay both ways, i.e. from left to right and from right to left across the reels.

Please Note: only active paylines can register line wins. However, the Scatter Symbol does not need to fall on an active payline. The Scatter Symbol will be discussed in greater detail below.

About the Paytable:

The Paytable will display all the winning combinations and their respective values. The standard symbol wins are multiplied by the line bet according to the Paytable. In the case of Captain’s Treasure, the number of winning symbol matches across the reels are called ‘Hits’.

All wins must start on either reel 1 or reel 5, they must then follow an unbroken chain of at least 2 symbols working from left to right, or right to left.  

Multiple wins are possible. These are added together according to the Paytable. As the lines pay both ways it is possible to get winning combinations from left to right and right to left in a single spin. However, when you get Five of a Kind (i.e. five symbols across the reels on a payline) you will only be paid once.

The Wild Symbol – represented by the Captain Symbol – can substitute for all other symbols (except scatters) to help form winning combinations. The Wild Symbol appears on reels 2, 3 and 4 only. The Wild Symbol will double any win that it is involved with.

Scatter Symbol:

The Scatter Symbol – represented by the Treasure Chest Symbol – does not have to follow the path of an active payline to form a win. The Scatter Symbols can be active anywhere on the reels, but must start on the leftmost or right most reel and appear consecutively to pay.

Unlike Line Wins, Scatter Wins are multiplied by the Total Bet with the values displayed in the Paytable.

It is possible to get both a Line Win and a Scatter win in a single spin. These are added together.

Dollar Ball:

When you play Captain’s Treasure online you can also enter a Progressive Jackpot side bet game called Dollar Ball. This is a lottery style game where you pick 5 numbers from a selection of balls (numbered 1-49). After each spin the Dollar Ball draw will take place, if you match 5 numbers to the drawn numbers you win the Progressive Jackpot. There are also cash awards for matching 1 or more balls. The payout for Dollar Ball can be accessed by selecting the Dollar Ball Menu from the top of the Paytable screen.

Please Note: The outcome for the Dollar Ball game is independent from any spin on Captain’s Treasure.

To Play Dollar Ball:

  • Select Enable from the Dollar Ball box at the top right hand corner of the reels.
  • A strip of numbers (1-49) will appear.
  • Choose 5 numbers by clicking on them. Clicking on a number twice will deselect it. Alternatively, you can choose Random Pick to select 5 numbers at random.
  • Click Activate when you have selected your numbers.
  • When you next spin the reels the Dollar Ball game will start, running alongside your standard spin.
  • When the spin has finished any winning Dollar Ball matches will be highlighted and winnings (if any) will be paid to you.
  • If you elect to spin the reels again you will be automatically entered into Dollar Ball again. If you do not wish to play Dollar Ball again, select the Disable button.

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.
