Castle Builder II

Castle Builder 2 is the sequel to the popular fantasy slot, Castle Builder by Rabcat Gaming.


Just like the original, this exciting new slot contains elements of medieval role-play and uses a level-based system that helps you work your way through fifteen different kingdoms using three different characters.

As the game's name suggests, the idea is to build as many castles as possible, and you have various construction materials acting as paytable symbols to help you achieve your goal.

You gain rewards for completing castles as well as cash prizes for arranging marriages between the local princess and an appropriate suitor. To top it all off, Castle Builder 2 has a free spins feature where you can collect even more construction materials cost-free.

More about the Software Provider

Rabcat is an Austrian online slots manufacturer which was established in Vienna in 2001. Its games are highly sought-after as they use handmade digital art, and many of its desktop and mobile slots (including Castle Builder) let players explore different environments, characters, and weapons. The most well-known Rabcat slot games include Asterix and Friends, Dragon's Myth, Mr. Vegas, and Frozen Diamonds.

Appearance and Sound Effects

You start off in Castle Builder 2 by selecting one of three characters to perform your construction projects. There's Sam the master builder, Mandy who's quite good at building but also has a Free Charm Feature which gives you free spins bonuses, and Igor (who is unlocked at higher levels) who's a fast builder and is accompanied by a feature that gives you expanded wilds.

On the left of the reels, there is the construction area which starts off as a lonely moonlit hillside but changes with each new construction project. The reels look as though they're part of a castle with each symbol occupying the place of a room.
Most of the paytable symbols exist to help you collect materials with which to build (e.g., granite, slate, bricks, and stone) while others merely exist to help you win prizes (e.g., crowns, gold ingots, your avatar, and treasure chests).

The music changes between the fifteen different kingdoms, and there are also appropriate sound effects for each environment such as howling wolves and the noise of shovels, mallets, and hammers.

Bonuses and Special Features

Your avatar (Sam, Mandy, or Igor) acts as the wild symbol in Castle Builder 2, and he or she can replace other symbols (except scatters) to create winning combinations.
Every win that's formed with one of the four construction materials, adds a block to the pallet at the bottom-right of the screen, and when a pallet is full, one section of the castle is completed. Once you've finished a whole castle, you move onto a new location to starting building another.

Every completed castle allows you to arrange a marriage between the princess and a suitor. If you're lucky, your chosen suitor will be accompanied by a handsome cash reward.
Three, four, or five scatters (N.B., the pink "Free Spins" symbol) anywhere in view gives you ten, fifteen or twenty free spins respectively. The Free Spins Bonus is the perfect time to collect more of those valuable granite, bricks, stone, and slate symbols for your next Castle Builder 2 construction project.

Paylines/Reels

Castle Builder 2 uses five reels, three rows of symbols, and fifteen paylines, and has an above average RTP (Return to Player Rate) of 95.50%.

Mobile Compatibility

The game is designed to work with desktops, laptops, mobile phones, and tablets, and includes mobile-friendly game controls when played on mobile devices.
