Getting Started:

When the game loads for the first time, a welcome screen will appear explaining some of the slot’s bonus games and special features. Press Start to go to the reels. Click the box marked ‘Do Not Show Next Time’ to skip the welcome screen the next time the game loads.

  • For the purposes of awarding payouts, the Total Bet is calculated as Coin Value x 25.
  • Winning combinations of symbols will be highlighted on screen after a spin. A winning spin will also activate the Collapsing Reels Feature, which will be discussed in greater detail in a section below.
  • All payouts are multiplied by the coin value. A list of payouts can be found on the Paytable, which is accessed via the Info button.

Info Pages:

Click the Info button to launch the slot’s Info Pages, which include the Paytable, information on bonus features and a guide to DC Superheroes Jackpots. Use the arrows on the bottom right to change pages, or click on the tabs on the top of the screen to go directly to a particular section. Press Reels to exit and go back to the reels. Descriptions of the Info Pages are found below:

The game is played with All Ways Paylines, which cover every possible position working left to right across the reels. In effect, this means that there are 243 possible paylines. You will be awarded a payout if three or more symbols appear on consecutive reels (starting on Reel 1) in any position.

Please be aware that there is a difference between the Total Bet and the Coin Value. The Total Bet is the amount staked on each spin. The Coin Value is used to calculated payouts on each payline. The Total Bet = Coin Value x 25.

About Payouts:

Payouts for all winning combinations in the main game can be found on the Paytables. All payouts are multiplied by the Coin Value when calculating winning combinations.

Only the highest value payout will be awarded on each of the paylines. Winnings from different paylines are added up and paid out as a total win.

Collapsing Reels will continue until no winning combinations appear on screen.

Note: Wild Symbols have different properties in Sticky Wild Free Games. This will be explained in detail in a later section.

Stacked Symbols:

Some of the High Paying Symbols – Riddler, Batman, Robin – can appear stacked on the reels. This means that they can cover more than one position on the reel, yet are made up of a single image. Each reel position will be calculated separately when it comes to paying out for winning combinations.

Bonus Symbols:

The Bonus Symbols appear on Reels 1-3 only. They do not have any payout value, however you will be awarded the Batman V The Riddler Bonus Wheel if three of them fall on the reels simultaneously (in any position).

Note: Collapsing Reels will not be triggered when three Bonus Symbols fall on the reels.

Mystery Spins:

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.
