Select Info to open the Firemen slot Info Pages, which includes information on payouts and special features.  You can flick through the different pages using the arrows on the bottom right of the screen, or click on the page titles running along the top of the screen. Select Reels to return to the main game. The Info Pages are shown below:

Payouts – this page displays the Paytable, which contains all possible payouts for the main game.

Feature – this page displays information on the special features can be awarded by the Burning Scatter Symbol.

Paylines – this page shows where all the paylines are positioned on the reels.


Paylines are the directions that matching symbols must follow across the reels to achieve Line Wins. Firemen slot features 20 fixed paylines.

About Payouts:

All possible payouts are listed on the Paytable. To calculate the value of a Line Win, multiply the figure shown by the Line Bet.

All Line Wins must begin on the first reel, moving left to right across the reels on a payline.

Only the highest winning combination is paid on each payline. Multiple wins can occur on different paylines; these are added together and paid as a total win.

Wild Symbol:

The Wild Symbol can substitute for all other symbols (except Burning Scatter) to form the best possible Line Win.

A group of Wild Symbols on a payline can also form their own unique Line Win with a separate payout.

Scatter Symbol:

The Burning Scatter Symbol does not need to fall on any payline to be part of the game. If a Burning Scatter lands on the reels after any spin, it will spread to other symbols, also turning them into Burning Scatters. When the Burning Scatters have stopped spreading, the fireman’s hose will douse the flames. The symbols will reveal one of the following:

  • Wild = an extra Wild Symbol replaces the Burning Scatter.
  • Win = a cash prize is instantly awarded.
  • Bonus = the Inferno Bonus is awarded (explained below).

Inferno Bonus:

When the Inferno Bonus is awarded all positions on the reels will change to Burning Scatter Symbols. You will be prompted to click on the Burning Scatters to reveal cash prizes. You can continue to click on the Burning Scatters, collecting more cash, until Collect is revealed; this will end the Inferno Bonus and award you the total of your collected cash prizes.
