Game Rules

American Dad!

40-line slot

The goal of playing American Dad online slot is to spin the reels and land matching symbols on the paylines. The game also offers you the chance to play Bonus Games featuring the characters from the TV series. While this is a modern video slot bursting with special features, it still gives a nod to traditional casino games like online blackjack and roulette.

How to Play:

The slot is played with 40 fixed paylines. You must first choose the amount you wish to bet on each payline.

  • Use the +/- buttons underneath the Line Bet Field to set the stake to the desired amount.
  • Spin the reels by using the Spin button or the Auto Play function. Auto Play will allow you to choose a set number of spins to be played consecutively. Press Stop (appears in place of the Auto Play button) to exit and play manually again.
  • Speed up the process of the reels spinning and game animations by pressing Stop (appears in place of Spin) or using the Turbo Mode button.

Note: The Total Bet for each spin = Line Bet x 40 (paylines).

Note: Winning combinations of symbols will be highlighted on the reels when the spin has been completed. You can view the payouts for each winning combination by accessing the Paytable via the Info button. All payouts are calculated by multiplying the appropriate figure by the Line Bet.

Info Pages:  

Click Info to access the American Dad Info Pages, which includes details of all payouts and bonus features. Use the arrows on the bottom right of the screen to move through the different pages. Descriptions of the Info Pages are provided below:

Paytable – displays all payouts for the main game and gives basic info on awarding of the bonus features.

Schmooblydong Wheel – describes the functions of the Bonus Symbol/Bonus Wheel.

Features – each page describes the Free Games/Re-Spin Bonus for each character:

  • Stacking Stan
  • Roger’s Random Wilds
  • Francine’s Holy Grail
  • Hayley’s Progressive Multiplier
  • Wheels and the Legman

Paylines – provides illustrations showing the positions of all 40 paylines on the reels.

Note: Use the Back button if you wish to return to the reels.


40 paylines are used, all working left to right in different positions across the reels. You will receive a payout for a Line Win if three or more identical symbols create a chain – starting on Reel 1 – on a payline.

Note: The Line Bet and the Total Bet are different. The Line Bet is the amount you choose to bet on each payline. The Total Bet is the amount staked on each spin, i.e. Line Bet X 40.

About Payouts:

A full list of payouts can be accessed through the Info button. The Paytable displays payout figures for all winning combinations. The payout figures are multiplied by the Line Bet.

Each payline will only award one winning combination. Payouts from winning combinations on different paylines are added up and paid out as a total win (displayed in the Win Field).

Wild Symbols:

Wild Symbols can appear on any of the five reels. They can form Line Wins in the same manner as standard symbols, or fill in for other symbols to make the best-paying combination on a payline.

Note: Wild Symbols cannot substitute for the Bonus Wheel Symbols.

Bonus Symbols:

The Bonus Wheel Symbols appear on Reels 1, 3 and 5 only. They do not have a payout value. However, you will be awarded a Free Re-Spin with special features if a Bonus Symbol lands on Reel 1 and 3 simultaneously. If a Bonus Wheel lands on Reel 1, 3 and 5 simultaneously, you will be awarded Free Games.

Free Re-Spin and Free Games:

When the Bonus Wheel Symbol lands on Reel 1 and Reel 3 as described above, the animations of the reels spinning will begin to slow before they have come to a stop. The Bonus Wheel on Reel 1 will spin and eventually land on a character from the American Dad TV Series. The second Wheel will spin and land on a number – 2, 3, 5 or 10.

If a Bonus Wheel lands on Reel 5, it will also spin and land on a number 3, 8, 10 or 25. Each Bonus Wheel refers to the following:

  • Reel 1 Bonus Wheel = Determines which character’s special features are applied to Re-Spin/Free Games.
  • Reel 3 Bonus Wheel = Determines the number of instances that a character’s special enhancements are applied, e.g. Wild Symbols, Win Multipliers.
  • Reel 5 Bonus Wheel = Determines how many Free Games are awarded with the above features.

If a Bonus Wheel does not fall on Reel 5, you will be awarded a Free Re-Spin with the special features applied from the character awarded on Reel 1’s Bonus Wheel.

If a Bonus Wheel falls on Reel 5, you will be awarded Free Games with the special features applied from the character awarded on Reel 1’s Bonus Wheel.

Find descriptions of each of the character’s special features below:

Stacking Stan:  

Before the Free Games/Re-Spin begin, a number of extra Stan Symbols are added to the reels. This number is determined by the Bonus Wheel from Reel 3. For example, if the Bonus Wheel had landed on 10, there would be 10 extra Stan Symbols added to each reel. These will appear in stacks (consecutively), so it is possible to play a spin and have the entirety of the reels covered with Stan Symbols.

Roger’s Random Wilds:

Before each Free Game or Re-Spin is played, Roger will appear on screen. He will walk across the reels and ‘vomit’ on random positions. This will add a Wild Symbol to that position. The Wild Symbols will remain in place for the subsequent spin. The number of Wild Symbols added for each spin will be equal to the number on Reel 3’s Bonus Wheel in the triggering spin. Roger will change the positions of the Wild Symbols for every spin in Free Games.

These Wild Symbols have the same payouts and behaviour as Wild Symbols in the main game.

Francine’s Holy Grail:

A number – determined by the number on Reel 3’s Bonus Wheel – of Klaus Patches will be scattered across the reels in different positions. If a Francine Symbol falls on one or more of the positions covered by a Klaus Patch, the Francine Symbol will expand to become a Stacked Wild Symbol.

The Stacked Wild Symbols will cover all four rows of a reel and can appear on up to five reels simultaneously.

The Klaus Patches will remain in the same position for each spin.

Note: The Klaus Patches do not have a payout value. They simply serve the purpose of changing the Francine Symbols to Stacked Wild Symbols.

Hayley’s Progressive Multiplier:

A Win Multiplier is applied to all payouts won during the Free Games or Re-Spin. The Win Multiplier is determined by the number on Reel 3’s Bonus Wheel. Therefore, if the Wheel lands on a 2 all wins will be doubled, if it lands on a 3 all wins will be tripled and so on.

After each Free Game has been completed, an animation will play showing a person approaching Hayley. If they pledge a donation to Hayley’s Save the Whales Campaign, the Multiplier will be increased. If they walk past Hayley, the Win Multiplier will remain the same.

Wheels and the Legman:

Roger and Steve will race across the reels before each spin of Free Games or the Re-Spin has been completed. They will leave a trail of Wild Symbols behind as the cross the reels. The number of Wild Symbols added to the trail will depend on the number displayed on Reel 3’s Bonus Wheel.

The Wild Symbols from the feature will act the same as Wild Symbols in the main game, substituting for other symbols and awarding a pay out if forming a chain on a payline.

Please note the following information concerning all Free Games:

  • Free Games are played using the same bets as the spin as the triggering spin.
  • The Bonus Wheel Symbols are removed from the reels during Free Games/Re-Spin. Therefore, Free Games cannot be retriggered.
  • The reels will spin automatically during all sets of Free Games.
  • You must press Click To Start to begin the Free Games. Press Continue to go back to the main game after Free Games have finished.
