Castle Builder 2 Slot

“Castle Builder 2” is a brand-new release from Rabcat on the Microgaming platform, based on its far less glamourous predecessor, Castle Builder. This 5 reel and 15 payline game does not feel like other slots, and does well to combine features of classical slot playing and normal strategy entertainment games together, to provide a special progressive slot with a great storyline.

Review of Castle Builder 2

Set in Medieval times, this slot features extremely beautiful graphics and animations that compete with the leaders in beautiful gaming such as Yggdrasil, Play ‘n Go, and NetEnt.

With a number of different scenic backgrounds throughout the game, the reels are placed on the far right of the screen, and encased in a castle wall frame. Each main character has been well thought out, and includes a spec sheet of their strengths and personality. You see, this game involves you playing the game with various avatars with specific sets of abilities. It also involves unique castles that need to be built in various kingdoms. More about the game play in the Special Features section.

The crisp, clear, high resolution graphics present an intriguing slot, and the soundtrack does well to bolster the theme and era that the game is set in. Playing symbols include building materials such as brick, stone, slate, and granite, and although these are the lowest paying symbols, they are the most important ones, as they are key to building and completing each of the 75 castles in the game.

Other higher paying symbols include a treasure chest, gold bars, gold crowns, and signet rings. The Pink “Free Spins” scatter icon is a catalyst in triggering the free spins bonus feature, and is a most welcome addition to the game. The WILD symbol is the representation of whatever avatar you are playing with at the time. This icon will substitute for all standard playing symbols, except the free spins scatter icon, to help complete winning combinations.

The game controls are all situated under the reels. The most obvious of which is the big green spin button, that allows you to maintain control of the game. Click it to spin the reels, and should they take too long to come to a stop, then click it again to bring the reels to an instant halt.

Other controls include:

  • AUTO SPIN - This is the control diagonally down to the left of the big green spin button. Here, you can set the machine to automatically spin for you for a predetermined amount of spins. This is always handy when wanting to put the kettle on.
  • STAKE SELECTOR – Here you can adjust your line bet up and down to suit your wallet or style of play. Bets vary from 0.01 – 30.00 per line.
  • LINE SELECTOR – This slot is not a set 15 payline game, therefore you can select with these arrows how many lines you would like to play per spin.

Special Features

Because this game is so different to most other online slots out there, I thought that it would be suitable to include the different forms of game play under “Special Features”, as it is rather out of the ordinary.

Constructing Castles and Progressing Through the Levels

Before game begins, you will need to select a character as your avatar for the next few stages. Each character comes with a host of different personality, bonus features, and advantages/strengths.

  • SAM: Master Builder – No Game Bonus – Builds really fast.
  • MANDY: A charmer – Free Spins Bonus Game – Not as quick at building.
  • IGOR: Powerful Master Builder and Wild Card – Expanded Wilds – Very quick builder. Igor cannot be selected until the other two characters have completed all of their castles.

When rolling the reels, each combination win involving building materials will slowly start to complete the construction of the castle to the left of the reels. After all of the building grids for a specific castle are completed, you will be able to move on to your character’s next kingdom of rule, and start with the next castle build.

Each character has several districts to complete, with a castle to build on each one. Once you have completed all of the districts/castles for one Avatar, you will move on to the next one.

There are 15 different kingdom districts and 75 castles to build on 4 various difficulty levels. The first two and last one are only playable with specific characters. Once you have finished all 75 castles, you will receive a cup, and receive upgrades for your avatars. You will then begin from the start, but with added special features and an improved payout rates:

  • Bronze Cup – 95.5% RTP 
  • Silver Cup – 96.25% RTP
  • Gold Cup – 97% RTP
  • Diamond Cup – 97.75% RTP

Marriage Pick Me Bonus

After completing any given castle, suitors will come to town in pursuit of the princess’ hand in marriage. Pick a suitor to reveal an instant cash prize. 

Free Spins Bonus Feature

You can trigger 10, 15, or 20 free spins by landing 3, 4, or 5 Pink ‘Free Spins’ scatters on the reels respectively. Unfortunately, there is no win multiplier or re-trigger available on the feature, but it will help you collect an amazing amount of building materials needed to complete castles, and all for free.

Payouts and Maximum Winnings

Because this game is so new, it is not clear yet what the maximum winning potential is on this slot, unfortunately. What we do know is that the game variance is Low to Medium, which means that smaller and more frequent wins can be expected on a regular basis.

Final Verdict

This game stands alone, in my mind, for creativity. It combines recreational gaming and gambling together to provide a fun and quirky little hybrid game that actually maintains the ability to keep you engaged for long periods of time. 

There are other progressive slots out there, like Gourmet Ranch Riches and Viking Runecraft, by Play ‘n Go, but this slot runs out as a pure favourite for me. Patience and endurance will see you playing on a RTP of nearly 98%, which is much higher than any other online slot.

So, if frequent and decent wins are what you want, with an entertaining theme to accompany it, then do not seriously look any further than Castle Builder 2 by Microgaming.
