The wild symbol is the flashing light from the top of the fire engine and it can substitute for all the other symbols, except the scatter, to help and form winning combinations.
The scatter symbol is the burning flame and while it does not offer any payouts, it is the key to all three of the slot's bonus features.
You only need to land one of the burning flame scatter symbols on the reels to trigger the bonus features. When the scatter lands the flames will spread to other reel positions and activate one of three bonuses. The further the flames spread, the bigger your potential wins.
The Firemen Wild bonus sees all the burning scatter symbols turn into wilds and the reels re-evaluated for wins. The Instant Win bonus awards a cash prize while the Inferno Bonus turns all the symbols into flames and you then click on them one at a time to reveal cash prizes until you find the ‘Collect' symbol.
Firemen offers a huge top payout of 500x for landing five of the wild symbols across a payline. The fireman symbol can payout up to 400x, the young woman can payout up to 300x, the old woman can payout up to 200x, the cat can payout up to 150x and the vase can payout up to 100x.
