Castle Builder, which was initially released in January 2013 on Win2Day gaming website, is an award-nominated casino game designed by Austria’s Rabcat Gambling. Castle Builder was re-launched on Odobo Play in February 2014, and has since been availed on Microgaming Quickfire. Castle Builder is a prequel to the relatively complex July 2017 slot called Castle Builder 2.

The terms “castle” and builder” indicate a virtual step by step castle building activity–it is typical of the medieval era–which the players must undertake. Castle Builder players are required to get two, three, four, or five matching medieval royal family members or wealth symbols in the main game; in the side game, getting more than two building blocks hastens the castle completion, which prompts the royal courtship and eventual wedding ceremony, thereby triggering bonuses.

Castle Builder Game Characteristics
Castle Builder has a 5X3 grid, which is the stomping ground for the fifteen adjustable pay lines. It consists of ten major symbols, and a few other supplementary symbols. The first batch of Castle Builder symbols has four royal family members: a blonde-haired princess “10”, a red-haired queen “Q”, a handsome prince “J”, and a bearded king “K”.

Second, there are: a brown gunny bag; two treasure boxes (a small basic chest and a big strong chest); a closed castle corridor with a red carpet; an aged, bald “Wild” castle architect; and building blocks. The supplementary symbols include a castle construction level meter and the royal children’s potential suitors.

When the Castle Builder software loads, a notice informs players of their goal: a fantastic and rewarding castle building-craze during which they brush shoulders with influential royal members. Next, there is a map of the three kingdoms—namely Ethrill, Ilrian, and Forana—seeking the castle builder’s expertise. For instance, the first castle building order is from King Forana’s ruler, called King Lomquer, for his princess’ so-called Small Summer Residence.

Castle Builder has a $0.01 minimum total bet ($0.01 bet X one pay line) and a $15.00 maximum total bet ($1 bet X 15 lines). Its eight bet values are $0.01, $0.02, $0.05, $0.10, $0.20, $0.25, $0.50, and $1.00. Pressing the spin icon starts the castle construction, which can be building from scratch or completing an ongoing building.

An example of $15.00 bet sheds light into the Castle Builder payouts that depend with bet size, where two, three, four, or five matches pay: blonde-haired princess “10” pays $2.00, $3.00, $5.00, and $10.00; prince “J” pays $3.00, $5.00, $10.00, and $50.00; queen “Q” has 4.00, 8.00, 25.00, and $75.00; king “K” gives $5.00, $8.00, $50.00, and $100.00; the gunny bag offers $0.00, $10.00, $50.00, and $250.00; the small basic chest $0.00, $15.00, $100.00, and $500.00; the big strong chest pays $0.00, $25.00, $200.00, and $1000.00; and the castle corridor pays $0.00, $200.00, $2000.00, and $20000.00. Five “Wild” castle architect symbols pays a non-progressive payout of $20000.00.

The images of the good castle Builder software and royal fanfare (ambient) sound effects—especially the soothing classic violin music—are considerably boosted by the realistic 3D graphics, particularly the construction site in the partially forested countryside, the humble suitors showing their professions, the matchmaking and wedding upon castle completions, and the sea-faring kingdoms’ medieval era mapping.
