Norse legend is the theme on offer in Troll Hunters, a 5×5 grid slot from Play ‘N Go. Boasting the Scandi developer’s usual high visual standards, it comes with cascading reels with expanding multipliers and a free spins feature. Join the hunt, on all devices, from between 20p and £100 per spin.

Visually, Troll Hunters is another classy effort from Play ‘N Go – set against a wintry mountain backdrop the reels include a range of Norse-inspired symbols. Look out for assorted blonde plaited Viking ladies, earrings, beer mugs and hunks of meat. They’re done cartoon style and look very good. Keep a special eye out for the golden rune which is the wild and substitutes for all other symbols.

The set up in Troll Hunters is a little unusual – instead of paylines, winning combinations are created when you land 3 or more of the same symbol either vertically or horizontally. After the payout is made, the winning symbols are removed from the reels and replaced by the symbols above.

A new calculation is made with the new symbols in place – these keep on coming as long as there’s a new winning combination on show. A win multiplier is applied on each drop, increasing with each 1 – the multiplier increases until you win the maximum 500 times your stake win. The middle symbol in each 3-line combo becomes a wild to offer even more winning chances.

Troll Hunters also comes with a Free Spins feature. You’ll notice the letters B.O.N.U.S can appear beneath the reels after the symbols have been removed – if you clear a whole column to reveal the whole word B.O.N.U.S, you’ll trigger 10 free spins.

These are played out on a new set of reels where winning combinations are created by landing 5 or more matching symbols anywhere on the grid. You can boost your wins with a multiplier here too. The precise amount depends on how many B.O.N.U.S lines you cleared when triggering the feature.

There are no wilds in play during the feature. Look out for the troll though – land 5 or more of these and you’ll trigger another round of 5 free spins. There’s up to 20 free spins to be won in total. If you manage to clear the board, a cash prize of 500 times your stake is awarded.

Troll Hunters offers a nice combination of quality design and exciting gameplay. The cascading reels keep the action flowing in the base game with the feature offering more of the same. The variance here is in the medium range, offering a balance between frequency and size of payouts.
