Players will find themselves in a spooky vampire castle with lots of castle inhabitants on the reels including the lady, lord, maid and groundskeeper.

This game offers a wild symbol and holy water feature that transforms other symbols into wilds and increases the multiplier by 1x. However, the highlight is the exciting free spins feature and the mega scatter free spins. These features can initially offer up to 21 free spins plus the former has a 1x increasing multiplier and the latter has an increasing multiplier that rises in multiples of two. Players can try and drain this game of the maximum 61,720x your bet wins.

How to Play

Spinning the reels of Castle of Terror is easy. Players can use the arrows to the right hand side of the reels to set their bet per spin. Hit the large green play button to get the reels tumbling. Bets per spin range from 20p to £8.

Winning combinations are formed in this slot game by landing three or more matching symbols on successive reels. This must be from reel one and go from left to right.

The symbols on the reels of this game are:

  • 9
  • 10
  • J
  • Q
  • K
  • A
  • Groundskeeper
  • Maid
  • Lord
  • Lady
  • ‘W’ wild
  • Silver castle scatter
  • Gold castle scatter


In the base game, the highest value symbol is the lady of the castle and she will award up to 50x your take for landing six matching symbols in a winning combo. The maximum win in this slot game is 61,720x your total bet and this can potentially be achieved in the free spins round.

Special Features

There are five special features in the Castle of Terror slot game:

  • wild symbol
  • holy water feature
  • free spins
  • mega scatter enhanced free spins
  • win exchange

The wild symbol is the large ‘W’ and this will replace other symbols on the reels to help form new winning combinations and award bigger cash prizes.

As you spin the reels in the base game, at least two symbols on the middle reels may be doused in holy water. This trigger the holy water feature. This can turn those symbols into wild symbols and increases the win multiplier by 1x.

Next, we have the free spins feature. Land three or more silver castle scatter symbols on any reel except reel six to trigger this round. The more scatter symbols you land, the more free spins you will be awarded:

  • Three silver castle scatters – 12 free spins
  • Four silver castle scatters – 15 free spins
  • Five silver castle scatters – 18 free spins

During this round, the win multiplier can increase by 1x as part of the holy water feature. The main character symbols on the reels will transform into wild symbols when they land on the reels and add 1x to the multiplier. When the multiplier hits a multiple of 20, you will get to drain the blood bank. This awards players an additional six free spins with no upper limit on the number they can receive.

If the gold castle scatter symbol lands instead, three or more will trigger the mega scatter enhanced free spins:

  • Three gold castle scatters – 12 free spins
  • Four gold castle scatters – 15 free spins
  • Five gold castle scatters – 18 free spins
  • Six gold castle scatters – 21 free spins

While the standard free spins round multiplier starts at 1x, in the mega scatter round, it starts at 2x and rises in multiples of two each time a character symbol lands on the reels and transforms into a wild symbol. Again, each time you reach a multiple of 20, the blood bank is drained and players are awarded six free spins.

There is the opportunity to make an exchange to get entry into the free spins feature with 12 free spins. This is available when players win 100x their bet or more and can click on the exchange button if they want to take up this offer. If you win between 25x and 100x your bet, you can exchange this for a game on a prize wheel that may award entry into the free spins. However, if you lose on the prize wheel, you will also lose your win and go back to the base game.

Graphics and Sounds

Castle of Terror is a vampire themed slot game that features beautiful, high-quality graphics from developer Big Time Gaming. Players will be transported outside the vampire castle where they will see blue skies, green grass, gravestones, the castle gate and the castle looming in the distance. The setting then changes to a dark and spooky room lit by candlelight inside the castle.

On the reels, the low value symbols are your standard playing card symbols including 9, 10, J, Q, K and A. The high value symbols on the reels include the groundskeeper, maid, Lord of the castle, Lady of the Castle and two castle scatter symbols. Scary, suspenseful music plays in the background as you spin the reels which works perfectly with the game, however, it does liven up when you get a winning combination.


Castle of Terror is a fantastic slot option for anyone who is a fan of the horror genre. The vampire theme is cool, even if it is not original, and the gameplay where you can potentially get up to 61,720x your bet makes this a very attractive slot to spin. The increasing multipliers and the two free spins features make this a go-to game for those who love to take advantage of as many free spins as possible. This is a game many players are sure to want to sink their teeth into today!
