On the right side of the screen, the Castle of Terror slot game's onboarding information is displayed. The green square with a white play sign is the play button, and clicking it will rotate the six reels with four rows each multiple times. With the aid of the stake section, users can alter their wager prior to each turn, and they can wager between 0.2 and 15 per spin.
The payout matrix for the Castle of Terror slot machine contains ten standard symbols. All symbols pay when three to six of the same appear on adjacent reels, beginning with the reel on the left. The highest-paying game also awards prizes for two identical symbols.
Six of these emblems (the lowest-paying ones) take the form of gem-encrusted playing card values in vibrant hues. Beginning with the light-green 9 and ending with the violet Ace. They promise rewards worth between 0.1% and 0.5% of your total wager.
The remaining four icons resemble the castle's inhabitants (the vampires). First, the eerie Gardener offers rewards worth between 0.25 and 0.6% of the bet. When three to six Maids appear on a payline, they can multiply your wager by 0.25 to 0.60 times. The Gentleman is here to assist users in winning rewards worth between 0.3 and 1 times their wager. The Lady offers payouts ranging from 0.5 to 50 times the total wager for two to six matching symbols on adjacent reels.
This release includes two Scatter symbols: a Silver Castle Megascatter and a Gold Castle Mega Scatter. If three or more Scatters appear on the reels, Castle of Terror will award 12 free spins plus three additional spins for each Scatter after the third (if feasible). If only one of the triggering symbols is a Gold Castle, your free spins will be enhanced.
You can purchase 12 free spins for seventy times your current wager (Bonus Buy feature) or 12 enhanced free spins for two hundred times your wager.
