Based on a tale of a legendary she-wolf, Asena is a 5 reel, 5 payline slot from Bally Wulff. Featuring simple design, this fast-paced game is a volatile beast whose main attraction is the free spins round. Play from between 10p and £100 per spin.

The legend of Asena centres on a grey wolf who found and raised a stranded, injured child. The wolf escapes her enemies and gives birth to 10 half-wolf, half-human boys. One of the hybrids goes on to become a leader of a clan who went on to rule a great realm.

That doesn’t seem like obvious source material for an online slot – back story aside, Asena is a very simple game. The reels include the usual assortment of A to 10 playing cards. They’re joined by a ring and a strange looking eye pouch. Both of these offer payouts of up to 150 times your total stake.

Asena the grey wolf comes next – land 2, 3, 4 or 5 of these in combination for a payout of 1, 8, 80 or 400 times your stake. Most lucrative of all is the mysterious woman – land 5 of her on a payline and you’ll pocket a mighty payout of some 1,000 times your total stake.

The magical book serves a dual purpose, acting as both the wild and scatter – land 3, 4 or 5 of them anywhere on the reels and you’ll trigger the Free Games feature and with it, 10 free spins.

Before the free spins begin, 1 symbol will be randomly chosen to become a magic symbol. If 2 or 3 of these are on the reels and a winning line is formed, you’ll also receive a scatter style payout after the normal evaluation has been made. It’s possible to retrigger more free spins here too. The magic symbol will remain the same.

Asena isn’t the most beautifully designed slot you’ll see and it’s not overloaded with features. The 5-of-a-kind symbol combinations can deliver some excellent rewards. As can the Free Games feature.

This is a volatile slot though – with just 5 paylines, expect plenty of lengthy spells when you’ll win very little. Likewise, you could face a lengthy wait to trigger the feature. The upside is that it’s possible to take down a hefty jackpot on a single spin. You’ll need deep pockets and plenty of patience here.

If you have both of them, then this strange tale of Asena the grey wolf is worth investigating. If you like wolves, NetEnt’s Fairytale Legends: Red Riding Hood is recommended.
