Castle Builder is a unique interactive type of online slot game that was developed by Rabcat. They designed the game to be highly interactive and entertaining in order to keep the players returning. The aim is to build ten castles in three different kingdoms by spinning the reels and gathering building materials. When a castle is completed a princess appears to choose amongst three suitors. This is the slots bonus game. Each suitor is worth a different level of prize and once she has decided on one, a wedding takes place and the respective prize is paid out. As every castle is completed the player also receives special achievements, or cash prizes, from the king which assists the player in moving up in ranking.

Castle Builder Slot Game Features

The Castle Builder reels are smaller than usual and situated to the right of the screen to make way for the castles on the left. The graphics are detailed and show the castle in progress as it is built and the sounds and imagery follow the medieval theme.

Castle Builder is a five reel online slot with a total of fifteen selectable pay lines. It can be played at online casinos. Betting levels per pay line are a minimum of 0.01 up to 1.00 making 15.00 the maximum bet allowed per spin. The auto play feature is a fast play option where the reels spin automatically for a predetermined number of times. As the reels spins and the required symbols land the castle builds up a lot faster with this feature.

The Castle Builder Online Slot Symbols

The most valuable symbol found on the Castle Builder reels is the locked castle door. These symbols pay out up to 20 000 coins when five land on an active pay line. The treasure chest symbol is the next highest valued symbol as it pays out up to 1 000 coins for five on an active pay line. Smaller chests and pots are next paying out up to 500 coins and 250 coins respectively. The royal family make up for the lower valued symbols and pay out smaller amounts when three to five matching symbols land on an active pay line.

The Castle Builder online slot reels also produce symbols displaying tools which are the special symbols that assist in building the castles. Two or more need to land on the reels in order for them to add pieces to the castle. These symbols come in a variety of different colours which award different amounts of caste pieces. Up to five castle pieces can be claimed on each spin.

Like wilds in many Apple Watch slots at https://onlineslotsau.com/Apple-watch, there is a wild symbol which is represented by the Castle Builder himself. He acts as a substitute for any of the regular symbols but not the special tool symbols that assist in building the castles. As a substitute he can assist in forming winning combinations which are paid out according to the value of the symbol that he substitutes for.

When a winning combination lands on the reels a four leaf clover appears from the bottom left corner of the screen to display the wining amount.
