Fire Siege Fortress is a 5 reel, 576 ways to win slot from Net Entertainment that can be played from 20p to £200 per spin on all devices including tablets and smartphones. With a medieval theme, it comes with a Fire Siege Free Spins feature, a Fire Free Spins feature, Tower Coin Win feature and 3 wild windows.

Visually, Fire Siege Fortress has a medieval theme to it and it set against a stone castle/fortress – with a valiant, sword-wielding knight standing to the left of the reel set, you have A, K, Q, J and 10 royals on flags as well as hammers, axes and swords.

You have the valiant knight too as well as a fire-breathing dragon – the latter is the most lucrative symbol giving you 2, 3 or 6 times your stake for 3, 4 or 5 across a payline. You also have a wild symbol which substitutes all symbols bar the scatter symbols.

During the base game, the wild windows can be triggered – there are 3 of them. Each wild window can be activated only once per spin and all of them can be activated at the same time on the same spin. Here are the details:

  • Archer Attack feature: a wild symbol landing on the bottom position of reel 2 will trigger this feature where 1 to 3 random wilds are randomly added to the reels.
  • Dragon’s Breath feature: this is triggered when a wild lands on the bottom position of reel 3. An expanding wild appears on reel 3 and changes all symbols on that reel into wild to give you a wild reel.
  • Trebuchet Assault feature: this is activated when a wild lands on the bottom position of reel 4. 1 or 2 Giant Wild symbols will randomly appear on the reels If the Dragon’s Breath and Trebuchet Assault features are triggered on the same free spin, only 1 Giant Wild symbol will appear. A Giant Wild symbol is a wild that expands 1 space down after it appear.

When it comes to bonus features, Fire Siege Fortress comes with a few – look out for the crown scatter symbol as 3 of them appearing anywhere on reels 1, 3 and 5 simultaneously will trigger the Fire Siege Free Spins feature. Each scatter appearing at the top of reels 1, 3 and 5 will give you 6 fire siege free spins each – each scatter appearing on any other position will give you 3 fire siege free spins. This means you could get as low as 9 free spins to as many as 18. The 3 wild window features can also come into play on each free spin as described above.

Now, look out for 2 crown scatter symbols appearing on reels 1, 3 or 5 as this will trigger the Fire Free Spins feature or Tower Coin Win feature. If the Tower Coin Win feature is triggered, you’ll simply win a cash prize of 5 times your total stake.

If the Fire Free Spins feature is activated, you will receive 3 Fire free spins – the wild windows can be activated meaning you can benefit from random wilds, expanding wilds and Giant Wilds on every free spin. If you were to get lucky with winning combinations formed with the high value dragon symbol, there’s 3,456 times your stake to be won on every single free spin!

Fire Siege Fortress looks amazing and is all about the bonus features – the key to winning big is the Fire Siege Free Spins feature where up to 18 free spins can be won. You could benefit from all 3 wild window features on every free spin resulting in expanding wilds, random wilds and Giant Wilds. All in all, this is a medium to high variance game so you need to be patient. By the way, it’s exclusive to online casinos from the Betsson Group such as Mr Smith Casino.
