Castle Builder Online Video Slot by Microgaming
Originally developed by Rabcat, the Castle Builder online video slot at Lucky Nugget casino Canada has been included in the Microgaming portfolio since 2014. Castle Builder is unique in that it brings together the progressive levels, tasks and storyline of a video game and the simplistic game of chance that is a five-reel slot machine.
With the slots, which feature 15 adjustable paylines, on the right side of the Castle Builder screen, the left side displays a building site. Here the player must construct castles to progress through successive rounds and activate bonus features.
Valuable Castle Builder Symbols
As one might expect from a tale of castles and royal families, the symbols in Castle Builder include a sack of gold, a casket, a treasure chest, a locked door, an old builder, and building materials, as well as a king, a queen, a prince and a princess.
The highest paying Castle Builder symbol is that of the old builder, which serves as a wild and can stand in for any other symbol, except the building symbols, to complete winning combination. Five old builders or five locked doors in an active payline yield the highest possible Castle Builder payout of 20 000 coins.
Castle Builder Bonus Games
In order to progress with the construction of each castle, the Castle Builder must acquire two or more building symbols – standard, bronze, silver or gold – from an active payline. It takes 11 building “blocks” to complete a castle and, once this the building is complete, the Castle Builder will be able to enter the bonus round, which means that bonus rounds take place quite frequently. The higher the value of the building symbols used, the greater the ultimate Castle Builder payout.
In the Castle Builder bonus round, the player must choose from three princes to wed a beautiful princess. Based on the player’s choice, an instant credit of a certain number of coins will be added to the total winnings.
There are four different levels – Forana, Ethril, Ilrian and Empire – each with its own bonus round, which the Castle Builder can complete to add the total payout, with a bonus round activated each time a castle is completed.
Additional Castle Builder Information
The castle that is currently under construction appears on the left-hand side of the Castle Builder screen and players can click on the icon of the old builder in the top left-hand-side corner to monitor their progress. Castle Builder players can monitor their credits on the bottom left-hand-side corner of the screen and can adjust their bet sizes or select the 15-coin max bet on the opposite side, below the reels. There are eight Castle Builder coin denominations, ranging from 0.01 to 1.00 and the minimum bet is just one coin per line.
Castle Builder also has the handy Auto Play feature that allows players to leave the reels to spin automatically a certain number of times, while the Castle Builder enjoys the chirping of birds and gentle hammering and other building sounds as the castle slowing takes shape.
