Hacksaw Gaming sets the stage in a frozen Nordic realm, where Thor’s legendary hammer and a lot of snow dominate the story. Symbols include mugs, horns, weapons, and characters, with wilds substituting across all reels.

The design blends icy backdrops with storm-charged energy, with both lightning and thunder featuring extensively. It delivers atmospheric tension from the very first spin. It delivers atmospheric tension from the very first spin. For players seeking epic journeys, it joins the ranks of the best online slot games this fall.

Gameplay and Mechanics

Hacksaw didn’t break any new ground here, but when you’ve had as many hits as they have, it probably doesn’t require a fancy new mechanic to get people playing. It uses a 5×4 line with only 14 win lines, which is laughably low for today’s slot titles, but seems to work here.

The base game is fine, but you know that any title with four bonus rounds, well five if you count the hidden one, is going to save most of the action for when we get to these. Plus, it encourages you to at least consider that bonus buy button.

You will need five of the coin symbols to trigger the Thunder respins. The best part of that is the game now only delivers coins, chests, and of course blanks. Land a coin or a chest, spin again; if only blanks, then that is the end.

Land either three or four of the scatter symbols, in this case a blazened FS shield, and you will find yourself facing the bonus round menu.

The Sticky God reel adds multipliers for big wins

Bonus Features

If you land three shields, you can choose either Stormbreaker or The Wild Storm. With four shields, however, we progress to Legacy of Lightning or Hammer of the Heavens.

StormBreaker

You’re guaranteed 2 coins and 1 chest with each of your three free spins in this round. Each spin also triggers a Thunder Respin.

The Wild Storm

If sticky wilds are your jam, The Wild Storm is the choice for you. 10 free spins, and all wilds stick around til the end. Even better, each wild can have up to a 100x multiplier and add together if you land more than one.

Fill a whole reel with wilds and you get to see the Sticky Wild God Reel. Hey, look, we don’t name these things. But if you land some scatters in this bonus round, you can get even more free spins before the round ends.

Legacy Of Lightning

This is basically the Stormbreaker bonus, but this time each spin is guaranteed 4 coins and a chest, and yes, there are still Thunder Repsins. Now though, if you can find the Mighty Mjolnir, you can get a 2x to 20x multiplier, which will considerably brighten your day.

Hammer of the Heavens

As you might have guessed, this is The Wild Storm bonus, but now with Hammers. Land Mjolnir and its 2x to 20x multiplier will add to the other wilds or possibly Sticky Wild God Reels when you reach the end of the current free spins, then we start over the next free spin, as in The Wild Storm all scatters can earn more free spins.

Blessing of the Bifrost

Unlike the other bonus rounds above, you can’t purchase the Bifrost Blessing Bonus Round in the Feature Buy menu. It’s a hidden bonus round that unlocks when you land 5 free spins in the base game.

It doesn’t tread new ground however, it’s the Legacy of Lightning Bonus round again, but this time with 5 coins, 1 chest and at least one Mjolnir Hammer for each Thunder Respin.

Feature Buys

200x gets you either the premium bonus rounds of Legacy of Lightning or Hammer of the Heavens, while a mere 100x gets you The Wild Storm or Stormbreaker.

If you’re on a budget, you can spend 50x to get Goldy Feautre respin which will get a guaranteed 3 coin, one chest Thunder Repsin, and for a mere 3x you can have Bonus Hunt which makes it five times more likely you will be awarded a bonus.

Final Verdict

It’s a high-volatility Norse epic, with a slightly cold and dark background. In any of the bonus rounds, the slow base game can suddenly jolt into high action, and the promise of the 15,000x will keep you spinning for more.

As with all Hacksaw Games, the visuals are crisp and edgy, and the music helps amplify the suspense. There are a ton of bonus buys for those that prefer to buy their way to excitement, and still a lot for the casual player to like, not least of which is the 96.32% RTP.
