RTG's Crimson Castle Slot Game Now at OnlineCasinoGames

RealTime Gaming has brought a haunting new slot to OnlineCasinoGames with the launch of Crimson Castle. The Halloween-themed title transports players into a mysterious castle beneath a blood-red moon.

Dark imagery sets the mood as wolves, bats, owls, and a black steed populate the reels. Meanwhile, Golden Coins and Moon Symbols introduce the game's central prize-collecting mechanics.

Crimson Castle: What are Its Main Features?

Crimson Castle uses a 5×3 layout with 10 fixed paylines. It offers a 95% RTP and supports bets from $0.10 to $10.00 per line. Its listed maximum payout reaches 50,000x the bet per line.

Crimson Castle keeps its base gameplay straightforward while placing its strongest emphasis on Special Symbols. Winning combinations form when matching symbols appear consecutively from the leftmost reel.

The Wolf delivers the highest regular-symbol payouts, while the Black Steed, Bat, and Owl provide additional premium combinations. Lower-value A, K, Q, and J symbols complete the standard paytable.

A Wild substitutes for regular symbols, although it cannot replace Special Symbols. Those Special Symbols become particularly important when players enter the game's bonus mechanics.

Special Features

Hold & Spin

The Hold & Spin feature forms the centerpiece of Crimson Castle. It activates when six or more Special Symbols land anywhere across the gameboard.

Once triggered, the Special Symbols lock in place, while three respins begin. Every new Special Symbol locks into position and resets the respin counter to three.

The feature can also introduce random Multipliers on available positions. When a Special Symbol lands on one of those positions, its value receives the applicable Multiplier.

Moon Symbols add another layer to the feature. They collect the current values of Special Symbols, including Mini, Minor, and Major Symbols. The collected values then increase the Moon Symbol's total.

Triggering Moon

The Triggering Moon feature provides another route into Hold & Spin. It can activate randomly whenever at least one Special Symbol appears on the gameboard.

When activated, the feature awards additional Special Symbols in random positions. It continues until enough symbols appear to reach the six-symbol requirement.

As a result, players can enter Hold & Spin without landing all six qualifying symbols through a single regular spin.

Buy Feature

Players can also access a Buy Feature through the dedicated Buy Feature panel. This option allows players to purchase a triggering spin for a selected feature.

After the purchase, the triggering spin plays automatically and activates the corresponding feature. The standard rules then apply throughout the resulting bonus round.

Verdict

Crimson Castle gives RTG's latest release a distinctly gothic identity while keeping its gameplay centered on cash-collecting mechanics. The combination of locked Special Symbols, respins, Moon collections, and Multipliers creates the game's main source of excitement.

Its 5×3 layout and 10 fixed paylines keep the base game easy to understand. Meanwhile, the Hold & Spin feature adds greater depth when Special Symbols begin appearing across the reels.

The title also fits naturally into the Halloween season. Its blood-red moon, haunted castle setting, and supernatural symbols reinforce the theme without distracting from the mechanics.

For players exploring US online casinos and other markets where the game is available, Crimson Castle offers another RTG title to add to their slot rotation. 

OnlineCasinoGames also provides a free-play version, allowing players to explore the mechanics before choosing whether to play the real version.
