Online Casino Game Rules

Batman and the Batgirl Bonanza

60-line slot1 of 4 DC Super Heroes Jackpots.

The main objective when playing Batman and The Batgirl Bonanza online slot is to spin the reels and match symbols on the paylines. The game also offers a range of special bonus features and offers you the chance to win of four DC Superheroes Jackpots. This popular casino game is a firm favourite with players of online blackjack and traditional slot games.

How to Play:

Press Start on the welcome screen page to go to the reels. The welcome screen details some of the special features and awards. Check Do Not Show Next Time to skip the welcome screen the next time the game loads.

  • Adjust the Total Bet to the desired amount by using the +/- buttons located on the bottom of the screen.
  • Click the Spin button to spin the reels and start the game.
  • Use Auto Play if you would like to set a number of spins to be played consecutively. Auto Spins can be ended by clicking Stop (replaces the Auto Play button).
  • Switch on Turbo Mode if you would like to speed up the game’s animations for faster results.

Please note:

  • The slot is played with 60 fixed paylines. For the purposes of payouts, the Total Bet = Line Bet x 60.
  • Winning combinations of symbols will be highlighted on screen after a winning spin.
  • Payouts are listed on the Paytable screen, which can be accessed via the Info button. All payouts are calculated X Line Bet.

Info Pages:

Click the Info button to access the Batman and the Batgirl Bonanza Info Pages. These pages include the Paytable, as well as detailed information on special features. Use the arrows on the bottom right of the screen to move through the pages, or jump directly to a section by clicking on the tabs on the top of the screen. Press Reels to go back to the main screen. Brief descriptions of the sections of the Info Pages are found below:

Payouts – lists all possible payouts, as well as providing information on special symbols.

Features – describes the Batgirl Locked Respins Feature and provides information on Batman Team-Up Free Games.

Paylines – provides illustrations that show the positions of all 60 paylines as they appear on the reels.

Jackpot – explains the rules and awarding of the DC Superheroes Jackpot Game.


60 fixed paylines are used in Batman and the Batgirl Bonanza online slot. The main objective of the game is to land matching symbols on these paylines.

Please be aware that the Line Bet and the Total Bet are different. The Line Bet is used to calculate Line Wins, equal to the bet made on each payline. The Total Bet is calculated as Line Bet x 60, and is the amount deducted from your balance per spin.

About Payouts:

A complete list of payouts can be found on the Paytables, which are accessed via the Info button. Payouts for each winning combination are multiplied by the Line Bet.

You will be awarded a Line Win payout for landing a chain of three or more symbols on a payline, starting on Reel 1.

Only the highest winning combination will be paid on each payline. Payouts for winning combinations on different paylines are added up and paid out as a total win.

Wild Symbols:

Wild Symbols can stand in for all other symbols (except Bonus) to form winning combinations on paylines.

Wild Symbols can also award a payout (displayed on the Paytable), when groups fall on a payline like a standard Line Win.

Bonus Symbols:

The Bonus Symbols appear on Reels 3, 4 and 5 only. They do not have any payout value. You will be awarded Batman Team-Up Free Games if three or more Bonus Symbols appear on the reels.

Bonus Symbols work as Scatters, meaning they do not need to fall on paylines and will be active regardless of their position on the reels.

Co-Op Symbols:

The three highest value symbols – Batman, Robin and Batgirl – will also appear as Co-Op Symbols, meaning a combination of two of those symbols can appear in the same position. Winning combinations featuring Co-Op Symbols will be paid the same as the payout featuring one of the symbols.

For example:

A Batman Symbol on Reel 1, Co-Op Batman/Batgirl Symbol on Reel 2 and Batman Symbol on Reel 3 would award the payout for three Batman Symbols on a payline.


A Co-Op Robin/Batgirl Symbol on Reel 1, Wild Symbol on Reel 2 and Co-Op Robin Batgirl Symbol on Reel 3 would award the payout for three Robin Symbols and three Batgirl Symbols on a payline.

Stacked Symbols:

The Batman, Batgirl, Robin and Co-Op Symbols can appear Stacked on the reels. This means that they can cover some or all of the positions on a reel. Although the Stacked Symbols are made up of one image, each position on the reel will be calculated separately.

Batgirl Locked Respins:

If the same symbols cover all of Reel 1 and Reel 2, Batgirl will lock the four symbols in place and award five Free Respins.

The Respins will play through automatically, with winnings accumulated and displayed on the bottom of the screen.

Wild Symbols and Co-Op Symbols will count where applicable for the Batgirl Locked Respins.

Note: Batman Team-Up Free Games cannot be awarded during the Batgirl Locked Respins.

Batman Team-Up Free Games:

Free Games will be awarded when three Bonus Symbols land in any position on Reels 3, 4 and 5. Press Click To Start (replaces Spin) to launch the Bonus Screen. A short clip will play showing a scene for the Batman TV series. Press Skip to move to the next screen.

The first stage of the Free Games Bonus will determine how many Free Games you will be awarded. The Bonus Screen displays a grid with 12 squares.

Click on the ‘Pick Me’ squares to reveal symbols corresponding to Batman, Batgirl or Robin. Each time you reveal a symbol it will be recorded in the collection area next to each character. The number of Free Games awarded depends on which character’s collection are is filled first:

  • Reveal three Robins Symbols to win 12 Free Games.
  • Reveal four Batgirl Symbols to win 17 Free Games.
  • Reveal five Batman Symbols to win 25 Free Games.

Press Start to begin playing Free Games. The spins will play through automatically, with winnings totalled for each spin and displayed on the bottom right of the screen.

During Free Games, 2x2 Super Symbols are used for the first two reels. These symbols are made up of a single image that span all four positions on these two reels. Each position on the reels will be calculated individually when it comes to paying Line Wins. Co-Op Symbols and Wild Symbols can also appear as 2x2 Super Symbols on the first two reels.

Please note:

  • Free Games cannot be retriggered. The Bonus Symbols are removed from the reels during the feature.
  • All Free Games are played with the same Total Bet as the spin that awarded the feature.
  • Batgirl Locked Respins feature is not active during Free Games.
