Raven’s Cauldron by Moonvault Games Slot Overview
Raven’s Cauldron by Moonvault Games brings a moonlit laboratory to life with glowing potions, gold framing and a goggle-wearing raven. Its cascading symbols share a mechanic with Gates of Olympus, but here the raven throws moonstones onto the board to multiply winning rounds.
The standout is the persistent cauldron multiplier: Full Moon builds it through winning spins containing moonstones, while Eclipse adds moonstones even on losing spins. High volatility and a 10,000x maximum win complement these distinctive bonuses. Explore the free demo on BonusTiime without an account or deposit.

Raven’s Cauldron Slot Features

cascades, Moonstones, Grimoires, Full Moon, and Eclipse combine into a feature set built around matching symbols and evolving multipliers.
Cascades
Winning symbols burst and pay, then new symbols fall into the gaps from above. If the drop creates another qualifying win, it bursts as well and pays again. This chain continues until no further win forms, creating round-by-round progression without fixed paylines.
Moonstones
Moonstones add a second layer to each round. The raven throws them onto the board at the opening or after any cascade. Each one carries a multiplier, and all moonstones on a winning round add together before they multiply that round’s win. The values are:
- x2 Moonstone
- x3 Moonstone
- x5 Moonstone
- x8 Moonstone
- x10 Moonstone
- x15 Moonstone
- x25 Moonstone
- x50 Moonstone
- x100 Moonstone, the highest value
Grimoire
The Grimoire acts as the scatter. It does not pay on its own, but it triggers the bonus modes. Four Grimoires start Full Moon, while five Grimoires start Eclipse, both with 10 free spins. That gives the scatter real gameplay weight.
Full Moon
Full Moon awards 10 free spins and keeps one total multiplier for the whole bonus. The cauldron never resets, so each winning spin can build on previous moonstone values. If a free spin wins without a moonstone, it pays its normal value instead.
Eclipse
Eclipse also awards 10 free spins, but it adds two extra rules. A moonstone of x5 or more is guaranteed on every spin, and moonstones join the cauldron even without a win. Unlike Full Moon, Eclipse can build the cauldron multiplier even on losing free spins.
Bonus Buy
The bonus buy menu lets players purchase a feature directly instead of waiting for scatters. Raven’s Cauldron offers two options, both with the same 10 free spins but different price points and entry conditions.
- Full Moon: x100 the bet; buys 10 free spins with building moonstone multipliers.
- Eclipse: x300 the bet; buys 10 free spins with guaranteed moonstones.

Raven’s Cauldron Slot Review
Raven’s Cauldron builds its identity from a raven, a cauldron, and a lab packed with grimoires, moonstones and potion jars. The dark alchemy setting is not just decoration: the board actions and bonus names all lean into that witchcraft theme, giving the slot a clear, coherent personality.
The main draw is the moonstone system, especially how it feeds into Full Moon and Eclipse. Cascades keep rounds active, then the bonus modes turn every moonstone into a multiplier story. High volatility and a 10,000x cap give the game real upside, but the buy prices push risk sharply higher.
Raven’s Cauldron suits players who want a feature driven cluster game with a strong theme and a proper ceiling. The buy menu adds choice, but Eclipse at x300 the bet is a serious commitment. That makes it best for players who enjoy pressure, planning and bonus chasing.
Raven’s Cauldron Slot FAQ
How Do Full Moon And Eclipse Trigger?
Raven’s Cauldron uses the Grimoire scatter to trigger bonuses. Four Grimoires start Full Moon, which awards 10 free spins. Five Grimoires start Eclipse, which also awards 10 free spins. The trigger symbols do not pay by themselves, and free spins cannot retrigger during the bonus.
What Do The Buy Options Cost?
The bonus buy menu offers two options. Full Moon costs x100 the bet and starts 10 free spins with moonstone multipliers that add up in the cauldron. Eclipse costs x300 the bet and starts 10 free spins with a guaranteed moonstone of x5 or more on every spin.
What Is The Maximum Win?
The game caps winnings at 10,000x the bet. If a round or bonus reaches that limit, it ends immediately and pays the cap. That ceiling applies across the base game and bonus modes, so the top return stays the same whatever mode you trigger.
Can You Play Raven’s Cauldron For Free?
Yes, BonusTiime offers a free demo of Raven’s Cauldron. You can play it without a deposit or account, so it works well for checking the Cluster Pays board, the cascade flow, and the moonstone system before trying the game on a real balance.
How Does The Moonstone Mechanic Work?
The raven throws Moonstones onto the board at the opening or after cascades. Each one carries a multiplier, from x2 up to x100. On a winning round, all moonstones add together and multiply the win. Moonstones never burst, and they do nothing on rounds without a win.
