Yggdrasil has taken to the science lab to create Pyrons, a 5 reel, 20 payline slot that offers a chemically-inspired twist on the classic fruit machine. The action in Pyrons is all about the base game and more specifically the exploding symbols and expanding multipliers. Put on your lab coat and get creative from between 20p and £40 per spin.

If you’re expecting free spins and complex feature rounds then Pyrons probably isn’t the slot for you. If you’re after a hypnotically entertaining slot which features just a single, simple feature then Pyrons is very much worth a closer look.

That sole feature is the exploding symbols. After every winning spin, all of the symbols in the successful payline will explode and be replaced by another selection of symbols offering a second chance to win. If the new symbols create a winning combination, they too will explode offering yet another opportunity to secure a payday. The explosions keep on coming as long as there’s a winning combination on the reels.

And that’s not all as each winning payline is subject to a multiplier. A second successive explosion win will double your payout. Three in a row will treble it. Find four consecutive winning combinations and you’ll receive a 5x multiplier. Manage more than that and you can look forward to a massive 20x multiplier!

The visuals in Pyrons are impressive. Look out for six traditional fruit machine symbols, including oranges, melons, cherries, plums, 7s and stars. They’re all encased in liquid filled, spherical containers that smash (complete with the appropriate sound effect) on winning spins.

The star is the biggest paying symbol, offering payouts of 2,500 coins if you manage to find five in a single payline. Three symbols are enough to get a winner and set the explosions off. The reels have a slightly futuristic look and are complemented by a catchy, electronic backing track that stays just the right side of being ZX Spectrum style annoying.

Simple it maybe but Pyrons has a hypnotic quality that makes it very enjoyable to play. It looks a treat and the pace of play is fast which makes for a winning combination. Get those symbols rolling and the multipliers can soon deliver some potentially explosive results. Saying that, it’s not the kind of game I think I will play regularly with other Yggdrasil slots like Cazino Zeppelin and Chibeasties more appealing.
