Frankenstein Slot Game Theme and Overview
Cave King is not a modern slot by any means. That's because the game was launched back in 2011 when online slot technology was still in its early stages. But despite this, the online game perfectly holds its own against modern slot machines. It boasts of sharp graphics backed up by cartoon-styled symbols. The background audio is also immersive enough to teleport gamers back to when man lived in caves.
Having said that, Cave King free slot is played on 5 reels with up to 30 paylines. You'll find two human symbols on the gameboard, representing the king and his wife. As expected, the king himself is the premium symbol, followed by his wife. The slot also features multiple free spins and the lucrative Multiplier Bonus.
After its release, Cave King online slot enjoyed immense popularity in the early 2010s. Surprisingly, the game is still trendy among players in Italy and the US.

How to Play this Cave King Free Slot Machine
Playing Cave King free slot doesn't need any prior slot machine experience. Just find a top-ranked online casino and fire up the game. As usual, most reliable casinos allow players to play the free demo version of the game before going full throttle. So, use this opportunity to learn things like the hit frequency, variance, storyline, etc.
With that in mind, Cave King free slot is played on a 5x3 grid with multiple symbols. As said before, Cave King himself is the premium icon, netting players 30, 150, and 750 coins for landing 3, 4, and 5, respectively. His beautiful lass follows with 20, 100, and 500 coins for a similar combination.
You'll also come across prehistoric animals that pay out decent amounts. Landing five dinosaurs will give you 250 coins, whereas five sabre-tooth tigers pay out 150. Also, landing 3 to 5 giant mammoths pays out 15 to 100 coins. The low-paying A-10 royals wrap it up, paying out 5 to 50 coins for 3 to 5.
In the meantime, the king doubles up as a wild logo, substituting all other standard icons when he makes the grand arrival. He pays 50, 500, and 2,500 coins for 3, 4, and 5. You'll also see the C-R-O-W-N symbol, representing the game's scatter, which triggers bonus games.
To play this free online game, begin by adjusting the number of paylines and bet per line. Then, place a bet with as little as $0.01 per line or as much as $300. If you're a high roller, select the maximum 10 lines by $100. Another thing, you can activate 25 automatic spins using the Autoplay feature.
Frankenstein Slot Bonus features
For a game that was launched almost a decade ago, Cave King online slot performs relatively well in terms of game bonuses. It packs multiple Free Spins and an impressive Multiplier Bonus feature. Now this means wins here can be staggering. Below is an overview:
- Free Spins:To activate bonus spins, players must land at least 3 scatter icons on any reels. Landing 3, 4, or 5 activates 7, 10, or 15 free spins, respectively. It doesn't stop there; hitting any of the five CROWN letters activates up to 5 free spins, one for each letter.
- Multiplier Bonus:Once the bonus games are over, players select a CROWN that adds a multiplier to their wins. The available multiplier values include 3x, 4x, 5x, and 10x. So, collect a CROWN and reveal the multiplier!
Cave King Slot Machine RTP, Volatility & Jackpots
Cave King's volatility is rated medium, which should bode well with both high rollers and budget players. This means decent wins can be hit once in a while. And yes, you don't have to wait for far too long to do that.
RTP-wise, Cave King free slot offers a 94.90% RTP value which is quite low. However, it's not the worst from the developer as games like The Pixies of the Forest offers a mere 93.95%. All in all, don't play the Cave King slot if you have a stretched budget.
Finally, this free to play online casino game has a jackpot potential to reach 750,000 coins. For example, you can land a winning combination with the wild on a single spin. Then lucky enough, you get a 10x multiplier at the end of the free spins round. This can give you a life-changing sum of 250,000 coins. Honestly, not many free online slots can pay like this.

Cave King's 5x3 layout and stunning graphics are excellent for both mobile and PC play. This online slot is fully compatible with both iPhone and Android phones, and the gameplay is glitch-free. Also, no download is needed. Just fire up the mobile casino and enjoy the show.
