Castle of Terror 2 Review

Why would we want to head back into this ghastly building? The simple reason is that our balances could be transformed into something terrifyingly brilliant throughout the course of this base game and free spins bonus. I won't give it all away just yet, so scroll down and find out why this will make the hairs on the back of your neck stand on end.

Gameplay & Features

The base game looks a little gruesome but shouldn't cause any concern. Wins are formed by matching between two and five scatter symbols but don't expect any huge returns. The highest payers are the brains and these will get you 1.5x for a 5 of a kind combination. 

Wins begin on the first reel and pay from left to right with matching symbols landing on consecutive reels. 

Things start to heat up as the bonus respins take place and you'll find one of these when one scatter symbol lands. The outcome depends on where this symbol appears but it could be one of five.

Firstly, all reels might be enhanced with extra brains or you could see a random multiplier. The third option is multipliers added to wilds and then there's a random symbol which adds wilds on 2 reels. Finally, there's a random reel covered in wilds. 

Bonus Game 

Scatter symbols take you into the free spins bonus, which has a win multiplier starting at 1 and it gets better with every spin. You get two or three active bonuses and these depend on the reels where the triggering scatters land. 

You can pick up extra free spins and the modifier versions are a little more advanced than before. You still have the extra brain symbols, wild multipliers and random multipliers that you saw before but now you can also enjoy a monster version, which turns regular symbols wild. Plus, there’s a horror version, which gives you reels filled with wilds on every spin. 

The direct bonus buy-in options cost 100x and 300x.

Castle of Terror 2 - Bonus Respins

Bonus Respins

When one scatter symbol lands, you get a respin, which is accompanied by a modifier. The enhancement you receive will all depend on which reel the scatter symbol lands, but the outcomes are all brilliant. You might have added wilds, multipliers and other treats.

Free Spins

As you trigger the free spins bonus, you're taken to an even darker setting where your wins could be about to explode. You start with up to three modifiers and these are determined by the triggering scatters. Once again, wilds and multipliers play an important role, along with a couple of added extras.

Win Potential

The modifiers are essential for landing better wins than the symbols can offer. Wilds, multipliers and other modifiers will be your best allies as you make your way through this terrifying experience. The high volatility is notable and just when you think it's personal and BTG wants to kill your balance, they fire it right back up again with a ridiculous reward. It is a tempting creation but you should be conscious of your balance while you go off in search of the 20,000x max win.

Design

This is a great-looking game and it doesn't matter if you're playing on a smaller mobile screen or on your desktop. The detail is sublime and the animations could not be better. The soundtrack is pretty good as well and they both work in harmony to bring you a feast for your eyes.

Our Verdict

Castle of Terror 2 is a top slot with plenty of potential but there is a big risk that your balance will suffer at the hands of these ghouls. It took me a while to get the modifiers working but once they did, the results were pretty special.
