Online Casino Games - Rules Explained

101 Roulette

The roulette wheel has 105 slots

101 Roulette is a simple casino game based on the classic game of roulette. However, this version uses a bigger, oblong track that is made up of 105 slots – 100 numbers, Zero and 4 Suits. The payouts are much bigger than traditional online roulette games, but the basic strategy remains the same.

The main objective is to place bets on where you think the ball will land on the roulette wheel/track.

Getting Started:

A range of chips is displayed in the horizontal belt on the left-hand side of the screen:

  • Select a chip value by clicking on it, then click again on the relevant part of the betting table. Each click – anywhere on the table – will add another chip of the same value.
  • Click again on a chip of a different value – if desired – to place different bets.
  • Press Undo to remove the last chip placed on the table.
  • Press Clear Bets to remove all chips and start again.

Note: You can place as many bets as you like, although you must adhere to the maximum and minimum betting limits (displayed on the upper left of the screen).

Note: You can click Double at any time to instantly double all bets on the table.

How to Play:

  • Press Spin to confirm bets and start the game.

The ball will be released on the wheel and come to rest on one of the 105 possible slots. Winnings bets will be highlighted on screen and paid (if applicable) into your balance. After the round is completed, the following options appear on screen:

  • Rebet = start a new round with the same bets on the table as the previous round. You can use the Clear Bets button to remove the chips and start again.
  • Rebet & Spin = start a new round with the same bets as the previous round, confirm and spin the wheel.
  • Double & Spin = double the bets of the previous round, confirm and spin the wheel.

Auto Play:

You can set a number of rounds with the same betting pattern to be played consecutively using Auto Play. To use Auto Play, place your bets as normal and hold down the Spin button. This will open an Auto Play slider which will allow you to set 10+ consecutive rounds with the same bets.

Note: You can exit from Auto Play at any time by clicking Stop Auto Play.

Table Layout and Features:

The top half of the screen holds the roulette track in the centre, a history panel on the right and a zoom-view of the ball on the left.

A coverage panel (located between the betting table and roulette track) will show the percentage coverage of all bets on the table.

The lower half of the screen holds the betting table in the centre, the game buttons on the right and the chip belt on the left. Above the chip belt there are two sliders that will allow you to set these two betting features:

Lucky Number:

This function will allow you to place a bet on all numbers at the border and corners of a selected number. For example, placing a chip on 45 would also bet on 34, 35, 36, 44, 46, 54, 55 and 56.

Quick Bet:

This function will allow you to quickly place a bet on all numbers forming a column and a row of a specific number. For example, placing a chip on 45 would also bet on 5, 15, 25, 35, 55, 65, 75, 85, 95, and 41, 42, 43, 44, 46, 47, 48, 49 and 50.

Note: you can use Quick Bet and Lucky Number at the same time if you want.

Betting Options and Payouts:

There are 105 different possible outcomes for the game. The roulette track features slots with the numbers 1-100, a Zero slot and 4 slots represented by Hearts, Diamonds, Clubs and Spades respectively.

Just like traditional online roulette games, you can place a bet on a single number, sequence of numbers or other outcomes. The table below shows the popular betting patterns and their payouts:

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.
