Castle of Terror Online Slot Review

The Castle of Terror online slot is a Vampire-themed game with a Gothic style across the 6 reels and 4 rows of symbols. There are 4,096 different ways to win, helped by wild symbols that acts as others when to complete combinations.

Other features include extra wilds and multipliers with splashes of holy water, plus a free spins round where the multipliers increase throughout. An enhanced version of the bonus games starts with a higher multiplier, making it easier to hit the vast maximum win of 61,720x your stake.

This is a highly volatile game with outstanding average returns of 96.72%. It comes from Big Time Gaming, and you can unleash the vampires on PCs or mobiles at some of the best slots uk casinos online.

How to Play the Castle of Terror Online Slot

The gorgeous graphics include a graveyard and the spooky castle of the title in the background. Decorative iron gates surround the 6x4 symbol grid, where you see bright playing card icons 9 through to A, along with 4 characters. An old Gardener, young Maid, Gentleman and Lady vampires appear, with creepy animations as they reveal their deathly grins.

The soundtrack is perhaps a little lively for the Gothic style, but this is a great-looking game across iOS, Android, and Windows mobiles at the top Betting Sites, as well as PCs.

The standard Big Time Gaming controls are proven to work well, and you can pick from a bet range of 0.20 to 15.00 per spin using directional arrows on the panel. Bonus Buy options cost 70x for the regular free games and 200x for the enhanced version.

The circular arrows on the controls lead to an autoplay mode, although like the Bonus Buy option, it’s not available in the UK.

To see how the features work, and how much you win with matched symbols on adjacent reels from the left, open the paytable with a click on the 3 lines button. The most valuable female vampire pays 0.5x, 1x, 2x, 3x, and 50x the stake when she’s on 2, 3, 4, 5, or 6 reels.

Free Spins & Other Features of the Castle of Terror Slot Machine

You can gamble prizes in an exciting Win Exchange feature. Wins of 100x can be exchanged for entry to the free games feature, while you can spin a gamble wheel if you land wins of 25x to 100x and enter the free spins round if successful.

A Holy Water feature can trigger on any spin, with water splashed onto 2 or more positions on the middle 4 reels. If water hits a character symbol, they transform into extra wilds, helping to complete combinations, and a multiplier increases by 1x for each affected symbol.

The ominous castle appears as special scatter symbols. The silver castle in any 3 places will trigger 12 free spins, with 3 more for any further scatters on the spin. If 1 of the castles is a gold version, the Enhanced free spins are awarded.

During the free games, the Holy Water feature triggers on every spin, and character multipliers don’t reset. In the Enhanced games, the multiplier starts at 2x and increases by 2x for each character splashed and turned wild with Holy Water. If any multiplier hits the maximum of 20x, you get an extra 6 free spins. Although scatters don’t appear in the free spins, so you can’t retrigger the whole feature.

Castle of Terror Slot Maximum Wins, Average Returns, & Volatility

The 61,720 maximum win is a far higher multiple than many other slots. Because the highest bet is just 15.00 per spin, the maximum prize is 925,800.00, which is still good, but not exceptional. The volatility is very high, so you could see fewer winning spins, but higher average prizes to make up for it.

The long-term payback percentage of 96.72% is outstanding. If you can take the high volatility, the Castle of Terror slot is a great choice for anyone looking for good value.

Our Thoughts on the Castle of Terror Slot Game

The popular vampire theme is captured perfectly here, with some great animations as they transform into grinning monsters. Holy Water can splash around at any time, and while it doesn’t guarantee a win, we found that it usually creates winning combinations with multipliers to boost the payout.

Holy Water turns symbols wild during each free spin and if you are lucky enough to trigger the Enhanced free games, the ever-increasing multipliers build twice as fast, for the best shot at a huge win.
