Crimson Castle Slot Review

I've been spinning Realtime Gaming's new Halloween release, Crimson Castle, for a few days now. If you've played any Hold & Win games before, you'll immediately know what to expect here. It's not exactly reinventing the wheel, but it has a couple of unique quirks, including a genuinely crazy bonus buy feature, that make it worth talking about.

Here's my honest breakdown of how it plays.

The game is basically built around one thing: the Hold & Spin feature. You trigger it the usual way by landing six special symbols (coins, moons, or jackpot tokens), though the game will sometimes randomly drop extra symbols to help you over the line.

But here's the wild part: you can buy straight into the bonus for just 1x your bet. Yes, 1x. It basically plays a triggering spin for the cost of a normal base-game spin. It completely changes the rhythm of the game. Instead of doing a traditional "bonus hunt" or paying 80x-100x just to see some action, you can just dip in and out of the feature for the price of a spin.

Once you're in, it's standard stuff: the regular symbols vanish, the triggering coins lock in place on the 5x3 grid, and you get three respins. Any new special symbol resets the counter back to three.

The absolute best part of this game is the Moon symbol. It acts as a collector, sweeping up the value of every coin and jackpot (Mini is 20x, Minor is 50x, Major is 100x) currently on the board.

The kicker? It doesn't clear the board after collecting. The coins and jackpots stay locked in place and pay out again when the round ends. So landing a Moon instantly doubles the money you already have sitting on the screen.

To give you an example: I bought the feature for 1x my bet. The triggering spin gave me four coins, a Mini jackpot, and a Moon. The Moon immediately swept the board for 42x. Because those symbols stayed locked and paid out again at the end of the round, that single 1x buy returned 103x. It's incredibly satisfying when it hits right.

To be fair, not everything in the bonus works perfectly. The game sometimes drops random multipliers onto empty spaces during your respins. If a coin lands there, the multiplier applies (and they can even stack).

In theory, this sounds great. In my session, it was mostly window dressing. I had a naturally triggered bonus run for eight respins where the game teased me with a bunch of multipliers on the board, but going by the final total, none of them lifted a single coin. I still walked away with a nice 110x win from the coins and a Moon, but having multipliers sit there doing nothing is a bit frustrating.

If you've played RTG's Fortunate Buddha, Fortunate Zeus, or Pharaoh Mysteries, this will feel very familiar. However, Crimson Castle is a definite upgrade, mainly because the RTP is bumped up to a very respectable 96.25% at its top setting (casinos can also run it at 87%, 91%, 93%, 94% or 95%), compared to the 95.00% listed for those older games.

It's also a big step up from RTG's recent Winnie the Piggie Las Vegas. Winnie has a similar collector mechanic, but the pig clears the coins off the board, whereas the Moon leaves them to pay twice. Plus, Crimson Castle has a 5,000x max win, blowing Winnie's 2,000x cap out of the water.

When you look outside of RTG, that 1x bonus buy really stands out. BGaming's 3 Lucky Monkeys Hold & Win has the same 5,000x max win and a collector symbol, but they charge 80x for the bonus buy. Amigo Gaming's 3 Fisher Cats has a 21,000x potential, but demands 113x for entry.

Crimson Castle isn't the most complex slot out there, and the dead multipliers can be a bit annoying. But the fact that you can trigger a Hold & Win feature for 1x your bet, combined with that awesome doubling Moon symbol, makes it a really fun, low-risk game to kill some time with this Halloween season.
