Despite being without Megaways™, Castle of Terror offers classic BTG gameplay in the form of a pulsating mix of wild transformations, progressive multipliers and the climax of a free spins round with enhanced modifiers.
Holy Water Triggers Wild Conversions …
The base game is all about a feature called Holy Water.
This triggered very regularly during testing – 29 times in 200 spins in fact. When it happens, night falls and a Holy Water bottle appears in front of the reels. It smashes and a shower of water splashes across them.
Two or more positions on the center four reels may be hit with water. If a premium character is in one of those positions, then it is converted into a wild and with each conversion, a global multiplier increases by 1x. You can see that at the top of the reels in the screenshot below. When the reels stop spinning, any wins are calculated and the multiplier is applied to all of them.
The Holy Water Feature triggeringThree or More Scatters Triggers 12 Free Spins …
The base game showed itself to be a bit slow in testing and to really unlock the best parts of Castle of Terror you need to unlock the free spins rounds. This is done by landing 3 or more Silver Castle or Gold Castle Scatters. That gets you 12 spins, with 3 more spins for each additional scatter appearing on the reels.
How is the free spins round more rewarding? Well, on EVERY spin, the Holy Water bottle appears, so that’s more wilds and more multipliers.
And … because the multiplier does NOT re-set between spins, it just keeps growing adding more and more value to every win.
And if you can drive that multiplier up to 20x, you’ll trigger an additional 6 free spins.
With Gold Castle Scatters You Enter Enhanced Free Spins
Big Time Gaming like an enhanced free spins round – see Wild Flower for another example. In this case, if one of your triggering Scatters is a Gold Castle, then you enter the Enhanced Free Spins round.
That means, your multiplier starts at 2x and increases by 2x with each Wild conversion. And just like the standard free spins, Holy Water is going to land on EVERY spin.
Whilst the Enhanced Free Spins is the better of the two, those Gold Castles are a big rarity, so use them well when they drop.
And If You Win 100x of More You Can Exchange To Enter Free Spins
Getting into the free spins round is what it’s all about and so BTG have also added another option – you can exchange wins for free spins, or the chance for free spins.
Firstly, any win over 100x can be swapped directly for entry to the standard free spins. Then, any win of 25x to 100x can be swapped for the chance to gamble for free spins on the spin of a wheel.
Land on green, you get 12 spins. Land on red, you lose everything!
