Castle of Terror

Despite the title, the Castle of Terror game unveils a not-so-scary visual that is inspired by a B horror movie. Instead of fear and dread, the game takes players to a rather exotic location with a sunlit landscape. However, when night falls, the atmosphere becomes different and fits perfectly with the theme. Indeed, vampires in search of prey appear on the screen. As far as the graphics are concerned, quality is the key, with a rather picturesque scene in the background, with a magnificent castle on top of the hill.

When you see the game panel, it looks like a metal grid with various symbols of characters and classic elements. On this point, the selection consists of four characters including the gardener, the maid, the gentleman and the lady in purple. The appearance of six of these icons on the screen allows it to win big during the session. In the base game or the bonus round, landing them grants a payout of 0.6 to 50 times the bet. In addition to these symbols, there are wildcards that substitute for all symbols to create winning combinations.

Compatible on all platforms, Castle of Terror slot is suitable for all players thanks to a variable betting range. Bets start from $0.20 and go up to $15 per spin. Similar to other BTG productions, the payout rate ranges from 96.72% and rises to 96.73% upon activation of the bonus purchase. As far as the grid format is concerned, this is not a Megaways configuration. To produce wins, you need to line up identical symbols on adjacent reels starting from the left side.

Castle of Terror compared to 3 other slots by Big Time Gaming

During the base game, Holy Water is randomly triggered with cash on the four middle reels. Once active, two slots with one of the characters turn into wild symbols. Each converted symbol increases the win multiplier value by +1. A payout evaluation is performed following the wild transformation process. On the next round of the base game, the multiplier resets.

Speaking of free spins, the slot introduces two scatters including a regular Silver Castle Scatter and a Gold Castle Scatter. By collecting three Scatters in any position on the reels, the player is offered 12 free spins and three additional spins with the obtaining of more Scatters. If it is the Gold Castle Scatter, enhanced free spins are awarded.

In all, the two Free Spins bonus rounds have a progressive win multiplier and holy water is triggered on every spin. In the standard free spins, the multiplier starts at ×1 and increases by +1 each time a character becomes a wild. In the enhanced free spins, the multiplier starts at ×2 and increases by +2 when a high-value symbol turns wild.

The accumulated multipliers do not reset between the free spins.

In both levels, the win multiplier tops out at ×20 including the award of 6 additional free spins. Depending on the jurisdiction, it is possible to purchase Free Spins for a cost of 70 times the stake or enhanced Free Spins at 200 times the stake.

Finally, those who want to enjoy free spins, they can use another alternative, the Win Exchange. Players have the option of exchanging 100 times the bet for 12 free spins or wagering their winnings to pocket free games. Once the wheel lands on a green segment, free spins are available. In case it lands on red, the bet and the free spin are lost.

Big Time Gaming’s Castle of Terror online slot has an interesting bonus round in store for players. Free spins are available incorporating win multipliers up to ×20. The jackpot reaches 61,720 times the bet.
