Diamond Bet Roulette

Exciting new betting options

The aim of playing Diamond Bet Roulette is to place bets on where the ball will land on the roulette wheel. This online roulette game uses 38 slots on the wheel, 0-36 plus a Diamond position. Bets on the Diamond Position can pay up to 100x your stake.

This game uses standard European rules.

Getting Started:

Choose your table limits from the welcome screen. Select Join to go to the roulette table.

  • Click on a chip to select it from the panel on the left-hand side of the screen.
  • Place the chip (by clicking again) on the part of the betting table you wish to bet on. Another click will place another chip of the same value. You can repeat the process with different valued chips if you like.
  • Press Undo to remove the chip that was last placed on the table. Press Clear Bets to remove all chips from the table and start over.
  • Press Double to instantly double all bets.

Note: you can place as many chips on as many different betting options as you like. However, you must stay within the betting limits selected on entry to the game.

How to Play:

  • Press Spin when you have made your betting selections.

The ball will be released on to the roulette wheel. As the ball spins, the sections of the outer wheel will light up in consecutive stages. Eventually, the ball will come to rest on one of the slots and one section of the outer wheel will be lit. Winning bets will be declared and you will be given the following options:

  • Rebet = start a new round with the same bets as the previous round. You will be given the opportunity to adjust bets if you wish.
  • Rebet & Spin = make the same bets as the last round and spin the wheel.
  • Double & Spin = double the previous round’s bets and spin the wheel.

Diamond Bet:

The outer wheel is used for the Diamond Bet. it is made up of sections, each showing a Multiplier or Jackpot. The Multipliers, ranging from X15 to X50, will be the payout award for a winning Diamond Bet. If the Jackpot section is lit, it will award winning Diamond Bets the maximum payout of 100 X the bet.

Auto Play:

If you hold down the spin button with your cursor, it will open the Auto Play feature. This will allow you to set 10-99 game rounds to be played consecutively with the same bets.

Press the Stop Auto Play button to exit at any time.

Table Layout and Features:

The chip selection panel is located on the left-hand side of the screen. You can scroll the panel to access different chip values.

The game buttons are displayed on the right-hand side of the screen. These buttons can change, depending on which stage of the game you are currently playing.

The betting table takes up the lower half of the centre of the screen.

The top half of the screen holds the roulette wheel, a zoom view of the wheel, the history panel and the racetrack.

Note: a display beside the history panel detail the number of spins since the Diamond Bet has been won.


Click on the racetrack to replace the betting table with the racetrack view. You can switch back again in the same manner.

The racetrack will display the numbers as they appear on the wheel, rather than numerically like the betting table. It will allow you to quickly place special betting patterns, including Neighbours, Orphelins and Tiers.


Neighbours Bets allow you to choose a number and also bet on the numbers directly adjacent to it on the wheel. You can choose 1-5 Neighbours, i.e. 1-5 numbers either side of your selection.

For example, choosing 17 with 3 neighbours would place a chip on 27, 6, 34, 17, 25, 2 and 21.  

Note: You can place combinations of Neighbours Bets if you wish.

Clicking in Tiers places chips on the 13 numbers opposite Zero. It covers around 34% of potential outcomes. 7 chips are used for the Tiers bet.

Note: the Diamond Bet is covered in the Tiers bet.

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.
