Firestarter is a devilishly themed, 5 reel, 25 payline slot from Novomatic. Played using a reel refill game engine, it also comes with a bonus feature that awards up to 25 free spins. Play this volatile beast of a game, on all devices, from between 50p and £100 per spin.

The first thing you’ll notice is that Firestarter is played using a reel refill game engine – after every successful spin, the winning symbols explode and are replaced by the symbols above. A new payout combination is made with the new symbols in place. The refills continue until there’s one where no new winning combination is visible.

The symbols on show include many fruit machine favourites, albeit with a demonic twist or two added – look out for cherries, lemons, melons and oranges alongside the male and female Firestarter characters. By far the top paying symbol is the lucky 7 which is embellished with the horns and tail of a devil. 5 of these on a payline will get you a payout of 5,000 times your line bet. There’s also a wild that replaces all other symbols apart from the scatter.

The box of matches is the scatter – when it lands on reels 1, 2 and 3 on the same spin, you’ll trigger the Free Games feature and be awarded 10 free spins. During the free spins, both the male and female Firestarters turn into scatter and payout anywhere on the reels rather than just in made paylines.

A bar symbol is added to the reels during the free spins too, offering payouts of up to 1,000x. Land 3, 4 or 5 scatters during the feature and you’ll re-trigger 5, 10 or 15 more free spins. The reel refills are in play during the feature too, offering even more winning chances.

We usually know just what to expect when firing up a Novomatic slot – namely simple visuals and gameplay and volatile action. That’s certainly the case with Firestarter, which is no oil painting as far as imagery is concerned but does deliver some fiery, high variance action.

If that recipe sounds attractive, then Firestarter will be a demonic delight. If you like the theme, you have NetEnt’s Devil’s Delight and Ash Gaming’s Innocence or Temptation which are good options.
