Turning trash into treasure is the goal in Incinerator, a 5 reel, 20 payline video slot from Yggdrasil Gaming. This isn’t any old rubbish though, it’s space debris that needs to be cleared. Look out for cascading reels which can also add plenty of extra bonus wilds to the reels. Get garbage mashing from between 20p and £40 per spin.

Instead of spinning, the 6 assorted space junk symbols drop down onto the reels – the top payer is the blue and yellow wheel-like symbol which will net you a payout of 200 coins if you land 5 on a payline. That may sound a little skinny for a top paying symbol but expect plenty of winning combinations. There’s also a standard wild symbol that substitutes for all other symbols.

After every successful spin, the winning symbols will be blasted away to be replaced by the symbols above – a second payout consideration will be made. The cascades will keep on coming as long as there’s a winning combo on view.

Many slots that use the cascading reels game engine offer an expanding multiplier with each successive cascade – that’s not the case here though. Instead, extra wilds are the added attraction. Land 3 successive winning cascades and a group of symbols will be turned into wilds (you can see precisely what pattern on the meter to the left of the reels).

This is repeated if you get 3 more wins. The more cascade wins you hit the better the wild offerings. Gather some real momentum and it’s possible to hit 6 wilds which can really get the coins flowing.

The pace here is uniformly fast in Incinerator – all of the action comes via the base game tumbles. The variance is pretty low compared to other slots from the Yggdrasil Gaming stable but if you get on a good run of cascades the extra wilds can deliver some very impressive hauls.

Space junk is hardly the most glamorous subject matter but who cares if the cascades keep on coming. If the added wilds work their magic, Incinerator shows that it really is possible to turn junk into something far more valuable. If you like cascading reels slots, NetEnt’s Pyramid Quest for Immortality is highly recommended. If you like Yggdrasil Gaming, Nirvana is superb and higher variance.
