A fantastical realm full of elves, wizards and unicorns is the setting for Wonder World, a volatile 5 reel, 5 payline video slot from Novomatic. The likeliest way to conjure a haul of treasure is via the Free Games feature where a magic sword can double or even treble your payouts. Play, across all devices, from between 5p and £50 per spin.

Set against a cloud filled backdrop and encased within an ornate picture frame, the reels include A to 10 playing cards as well as a magical castle, a book of spells, a mysterious princess and a crystal ball – 5 of the latter will get you a payout of 200 times your total stake.

Better still is the bearded wizard who is the game’s scatter – land 3, 4 or 5 of him anywhere on the reels and you’ll win 5, 25 or 500 times your total stake.

The most lucrative symbol is the white unicorn which is the wild, replacing all other symbols with the exception of the scatter and bonus symbols. Land 2, 3, 4 or 5 of these on a payline and you’ll pocket one, 25, 250 or 1,000 times your total stake.

Wonder World comes with a Free Games feature – to trigger it, you’ll need to land 3 of the Excalibur style sword on reels 1, 3 and 5 on the same spin. You’ll then be given 10 free spins. Before these begin, pick from 1 of the 3 swords – this will reveal either a ruby multiplier which doubles all payouts or the emerald multiplier which triples them. You can re-trigger more free spins so hope to see those swords fall into view (with up to 20 in total available).

Wonder World has a magical feel and it’s certainly possible to conjure up impressive amounts of treasure from nothing. Be warned though, this is an extremely volatile slot. There will be spells when your bankroll will disappear quickly.

If you can cope with the swings, there’s plenty to like though. The design is pretty good for a Novomatic game and the gameplay is as frantic as usual. Trigger the free spins with the maximum multiplier and Wonder World can deliver results that are wondrous indeed if fortune is smiling. If you like the theme, NextGen Gaming’s Great Wild Elk is recommended.
