Online Casino Games - Rules Explained

Green Lantern

243-ways slot1 of 4 DC Super Heroes Jackpots.

The objective of playing Green Lantern online slot is to match winning symbols on the paylines. The slot boasts lots of special features that could add a big boost to your winnings. Any spin could also lead to the awarding of one of four DC Superheroes Jackpots. Green Lantern joins online roulette, poker and blackjack among the most popular games at William Hill Casino.

Getting Started:

  • An info screen will detail some of the game’s special features awards when the game loads for the first time. Press Continue to go to the reels.

Note: Check the box marked ‘Don’t Show Next Time’ to skip the info screen the next time you load the game.

  • Before making your first spin, make your bet selections by using the +⁄- on the bottom of the screen.

Note: The Total Bet will be calculated as Line Bet X 40.

How to Play:

  • Click the large green button (Spin) on the bottom right of the screen to spin the reels and start the game.
  • Open Auto Play if you would like to play up to 99 spins consecutively. Auto Play will pause when a bonus feature has been awarded. Press Stop to exit from Auto Play at any time.
  • Check the box on the Turbo Field if you would like to speed up the game’s animations to enable faster results.

Please note:

  • Winning spins will initiate the Collapsing Feature. This will be explained in detail in a later section.
  • All payouts for winning combinations are displayed on the Paytable, which can be accessed by clicking the ‘i’ button on the bottom right-hand corner of the screen. All payouts are multiplied by the Line Bet.

Info Pages (i):

Clicking the ‘i’ button will open a range of Info Pages. These will detail the game’s special features, as well as providing a full list of payouts for Green Lantern. Use the arrows on the right and left of the screen to change pages. Press the X button (located on the top right-hand corner) to exit and go back to the reels. The Info Pages are described below:


  • Page 1 = Special Symbols.
  • Page 2 = High Paying Symbols.
  • Page 3 = Low Paying Symbols.


  • Page 4 = Collapsing Feature/Power Bar.
  • Page 5 = Fear Fight Mission.
  • Page 6 = Training Centre Mission.
  • Page 7 = Secret Sector Mission.


  • Page 8 = gives an explanation of the All-Ways Pays Feature.


  • Page 9 = provides details on the DC Superheroes Jackpots.

Paylines/All-Ways Pays:

Green Lantern does not use traditional slot paylines. Instead, wins will be awarded when 2/3 matching symbols appear on consecutive reels, with the first symbol appearing on Reel 1. In effect, this means that there are 243 different paylines, covering every position working left to right.

Please take note of the difference between the Total Bet and the Line Bet. The Line Bet is used to calculate each different winning combination. The Total Bet is the amount staked for each spin. The Total Bet = Line Bet X 40.

About Payouts:

Every possible payout is listed on the Paytable Pages. Each individual combination is calculated separately, with the payout figures multiplied by the Line Bet.

Only the highest value winning combination is awarded on each payline. Wins on different paylines are added up and the total displayed in the Win Field (bottom centre of the reels).

Wild Symbols:

Wild Symbols can stand in for all other symbols to make the best possible winning combinations. Wild Symbols can appear on Reels 2-5 only. They do not have a separate payout value.

Collapsing Feature:

The Collapsing Feature is triggered after every winning spin. The winning symbols will explode and the remaining symbols will fall to the bottom of the reels. New symbols will fall into place and the process will be repeated if another winning combination is made.

Note: Payouts will be awarded and accumulated during each wave of the Collapsing Feature.

Each time the Collapsing Feature occurs, an extra block will be lit on the Power Bar on the bottom right of the screen. You will be awarded one of the three Free Games Features if the Power Bar reaches four or more lit blocks.

The more blocks that are lit, the better the enhancements for Free Games.

  • 4/5 blocks = 1 Charge for Free Games.
  • 6/7 blocks = 2 Charges for Free Games.
  • 8 blocks = 3 Charges for Free Games.

Please note:

  • The Collapsing Feature will end if the 8th block is lit on the Power Bar.
  • You cannot change the betting selections during the Collapsing Feature.

Free Games:

You will be awarded one of the three Free Games Features if the Power Bar reaches four or more blocks after Collapsing Reels has finished.

The Green Lantern will randomly choose one of the three Free Games Features:

  • Fear Fight Mission
  • Secret Sector Mission
  • Training Sector Mission

Fear Fight Mission:

You will be awarded unlimited Free Games. These will play through automatically, with wins accumulated for each spin. During Fear Fight Mission Free Games, all symbols except Wild Symbols will explode after each spin. The Wild Symbols will fall to the bottom of the reels and new symbols will be added.

Free Games will continue to play until a certain number of Wild Symbols have been collected on the reels. The number of Wild Symbols will depend on the number of Charges on the Power Bar when Free Games Feature has been triggered:

  • 1 Charge = 5 Wild Symbols.
  • 2 Charges = 6 Wild Symbols.
  • 3 Charges = 8 Wild Symbols.

Secret Sector Mission:

You will be awarded 10 Free Games, which will spin through automatically. Winnings are accumulated and displayed on the bottom of the screen. Secret Sector Mission Free Games uses a Dynamic Multiplier which will multiply all payouts awarded. Each time the Collapsing Feature awards a win, the Multiplier will increase. The rate of increase and starting point for the Multiplier depends on the number of Charges on the Power Bar when Free Games Feature has been triggered:

  • 1 Charge = Multiplier starts on X2 and increases by +1 each wave of the Collapsing Feature.
  • 2 Charges = Multiplier starts on X2 and increases by +2 each wave of the Collapsing Feature.
  • 3 Charges = Multiplier starts on X3 and increases by +2 each wave of the Collapsing Feature.

Note: The Dynamic Multiplier can reach a maximum of X8.

Training Centre Mission:

You will be awarded 10 Free Games. All wins are totalled and displayed on the bottom centre of the screen. Before the reels begin to spin, the Green Lantern will add a number of extra Wild Symbols to the reels. The number of extra Wild Symbols will be increased by having more Charges when the Free Games Feature has been triggered:

  • 1 Charge = Grenade Wilds.
  • 2 Charges = Missile Wilds.
  • 3 Charges = Punch Wilds.

Please note the following information about Free Games:

  • All Free Games are played with the bet selections that triggered the initial Collapsing Feature.
  • The Power Bar is not active during Free Games, nor can lit bars be carried over.

After the last spin has been completed in Free Games, a summary screen will appear detailing the total win from the feature.

Press Continue to go back to the main game.

DC Superheroes Jackpot Game:

If you are playing Green Lantern slot for real money, any spin can trigger the DC Superheroes Jackpot Game. This will guarantee the award of one of four Progressive Jackpots = Mini, Minor, Major or Grand.

The DC Superheroes Jackpot Game is awarded randomly, although your chances will be increased if you play for a higher bet.

The Jackpot Game is played on a new screen. It will feature a grid of 20 squares on the left and a collection area for the Jackpots on the right.

  • Click on the squares to reveal coloured symbols that correspond to each Jackpot.
  • Fill the collection area for a particular Jackpot to win that award. The number of symbols required depends on the Jackpot:
    • Mini = 2 Green Symbols.
    • Minor = 3 Blue Symbols.
    • Major = 4 Yellow Symbols.
    • Grand = 5 Red Symbols.

Please note: The DC Superheroes Jackpot Game is played under a time limit. Make your selections within the allotted time, otherwise one of the four Jackpots is randomly awarded to you.

Progressive Jackpots:

Progressive Jackpots are ever-growing pots that are funded by both the players and the casino operators. A small percentage is taken from each player’s bets/spins on the game. The casino will also provide a base sum to start the Jackpots, which are normally called seeds.

The DC Superheroes Jackpots for Green Lantern are awarded and funded by William Hill Casino as shown below:

Seed (amount each Jackpot starts out with) = Mini €100, Minor €1000, Major €10,000 and Grand €200000.

Contribution Rate (percentage taken from each bet to fund Jackpots) = 0.99%.

Win Condition (result needed for Jackpot win) = Jackpot Game is awarded randomly. You will be guaranteed to win one of the four Jackpots on entry to the game.

Win Requirement (eligibility requirements for Jackpot Game) = play Green Lantern for real money at William Hill Casino.

Please note: Although seeds for Jackpots are displayed in Euros, UK casino players will be awarded the equivalent amounts in pounds sterling (GBP).

Return to Player:

The theoretical RTP (Return to Player) for Green Lantern online slot is 94.95%. This figure includes the Jackpot contributions of 0.99%.

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.
