Paylines are the directions that matching symbols must follow across the reels (left to right) to pay as Line Wins. Only the paylines that you bet on can record Line Wins.

Please note that there is a difference between the Line Bet and the Total Bet. The Line Bet is the individual wager on each payline. The Total Bet is the total wager on all paylines (added up).

About Payouts:

All potential payouts for the main game are displayed on the Paytable. Line Win = Payout x Line Bet.

Only the highest value Line Win is paid on each payline. Multiple wins can occur on different paylines; these are added together and paid as a total win.

A Line Win must begin on Reel 1, moving left to right across the reels in a chain of at least three symbols on a payline.

Wild Symbol:

The Wild Symbol can substitute for all other standard symbols to form the best possible Line Win on a payline.

The Wild Symbol cannot substitute for any of the Scatter Symbols (explained below).

Wild Symbols can also form their own Line Wins with a separate payout.

Scatter Symbols:

There are three Scatter Symbols uses in Cat in Vegas slot. They do not need to appear on any paylines to be active in the game.

  • Free Games are awarded if three King Show Scatter Symbols land on Reels 2, 4 and 5 simultaneously.

  • Whichever segment the Wheel pointer lands on will multiply your Total Bet. When a Multiplier has been awarded, that segment will be unlit on the Wheel. You will then be prompted to spin again. The total current win is shown in a display on the right of the Wheel.
  • From time to time, the Cat may nudge the Wheel after it stops to award a higher Multiplier.
  • You can keep spinning the wheel until the Wheel pointer lands on an unlit segment. This will end the Wheel of Luck Bonus.

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.
