Attack the castle with bow and arrow, dragons and catapults and try to capture the big payouts.

This Netent slot was released as an exclusive Betsson slot, but by now, it is also available in other online casinos.

Besides free spins and coin wins, this online slot comes with a very lucrative mystery wilds feature, making it stand out from the crowd.

Fire Siege Fortress gameplay & features

Fire Siege Fortress has a castle setup with real merlons. The 5 reels form a 4 x 3 x 4 x 3 x 4 setup, and the win all ways mechanism is active. In other words, there are 576 ways to win, and it doesn’t matter where the symbols drop on the reels as long as they hit the reels consecutively and from left to right.

You can bet from $€ 0.20, and up to a maximum of $€ 200, per spin.

The payout rate is 96.01%, and variance is medium.

Symbols and payouts

Keep an eye out for the dragons and knights, the most valuable symbols: they reward you 120 and 100 coins for 5 of the same.

The medium-value symbols, consisting of various weaponry, are good for 40 coins for 5-of-a-kind.

The well-known card symbols are now disguised as flags and are all worth 20 coins.

Mystery wilds

The bottom reel is a so-called hot zone of 3 positions next to each other. If one or more wild symbols hit these spots, you win one of three mystery wild boosters:

  • Archer Attack: 1 to 3 extra wilds appear on the reels.
  • Dragon’s Breath: The dragon spits wilds all over reel 3.
  • Trebuchet Assault: The catapult tosses huge wild symbols onto the reels.

The best scenario is if you get more than one wild symbol in the hot zone: then it is possible to combine boosters!

Free spins bonus

Three scatter symbols will activate the free spins bonus:

  • 6 free spins for each scatter at the top of the reels (in the battlements)
  • 3 free spins for each scatter in any other position

With two scatters (1 of which needs to be on a merlon), you can grab either three free spins or a coin win.

The free spins are the same as the regular spins during the base game. We think this is a bit of a missed opportunity. Things would have been more interesting if Netent had included some mystery features or extra multipliers.

Our verdict on the Fire Siege Fortress slot

This Netent slot is a fun treat you can enjoy in between other games. We wouldn’t go as far as to call it a classic, but worth a try, anyway.

We are particularly pleased with the stacked features. We haven’t been able to spin all 3 wilds in the hot zone yet, but we did manage to spin 2 out of 3.
