Castle Builder Slot Review

The Austrian software company Rabcat decided to satisfy those users who aspire for the theme of medieval castles and kingdoms. In 2014, they released the Castle Builder slot. It still occupies top positions in various CA online casinos. Many gamblers note that it resembles an exciting PC application due to innovative stylistic solutions and unsurpassed animation effects. This no download slot machine features a short cycle, low variance, and an RTP of 96.5%. So, you have to plunge into the surroundings of managing an ancient fortress, which will give you a lot of pleasant emotions thanks to the generous cash prizes.

How to play the Castle Builder slot

Castle Builder is a 5 reel, 15 pay-line video slot. The game layout is 5×3. To win real money, you need to bet on the result of each spin. Let’s take a look at the main characteristics of the slot mechanics:

  • You can adjust the number of active lines up to 15;
  • You can bet from 0.01 CAD to 1 CAD for each line. It is allowed to bet up to 15 CAD per spin;
  • To get the payout, you need to get a continuous chain of identical symbols with the active line, which must start from the 1st reel;
  • The maximum payout is x20,000 of your current bet;
  • The reels are located on the right side of the screen. To the left, you’ll see the castles that you’ll need to build. When you move to a new level, you will see a map and a task from the king;
  • You can run free demo play and find out all the slot features before making real money bets. Castle Builder game free is available 24/7/365 without depositing or logging in.

Castle Builder has a multi-level system of prize payments, special symbols, and other functions. You will build a castle by collecting combinations of special icons. When you manage to complete the next building, you will become a member of the bonus round, in which you are guaranteed a reward. The intuitive control panel includes all the necessary commands to interact with the basic and additional mechanics of the slot. Among them are such buttons as setting up lines, setting rates up to the possibility of turning them to the maximum, and keys for starting the spin and automatic mode.

Castle Builder Symbols & Payouts

The castle Builder stimulator’s reels depict various royal families’ representatives, treasure chests, bags of gold coins, a gate closed to a huge castle, and a castle builder (Wild), and special symbols with construction materials. Let’s take a look at the payouts of symbols:

  • Playing cards from 10 to A will bring from 10 to 100 coins;
  • Money bag will provide 250 coins;
  • A beautiful pink box will bring 500 coins;
  • The Royal Chest will provide 1,000 coins;
  • The picture of a closed-door will provide a payout of 20,000 coins;
  • Wild is their image of a builder-architect that will bring in 20,000 coins.

Wild is paid according to the general rules and can replace other symbols, except for materials, if necessary. Materials can be bronze, silver, gold, and those that do not carry any value. If two bronze, silver, or gold materials symbols form a combination within the active line, you’ll advance several steps. After completing work on the structure, you will take part in the bonus round. The remaining materials that were not involved will move to the next level of the online slot.

Castle Builder Bonuses

The slot has a thematic bonus round. You have to choose a husband for the princess who will live in this castle. There is a poor man with an average income and a rich man among the candidates. Your choice will affect which of the 3 amounts accumulated during the construction process will be yours. You can also get an additional prize! Having completed the next task, you will get a higher rank, which gives certain advantages.

  • Besides the common icons, it has construction symbols of five ranks. They spring up rather often and give you big wins. Note the more prize combinations they have, the more valuable the metal;
  • As the castles are built, you will increase your qualification level and receive new titles and awards from the king;
  • Any stage passed is associated with various cash prizes, and the higher you climb the mission ladder, the more valuable the payments will be.
