Castle Builder II

Castle Builder II is a medieval-themed video slot developed by Rabcat. The game is set in a fantasy world of kingdoms, castles, and royal marriages. The slot's background showcases picturesque landscapes with hills, forests, and castles perched atop cliffs, immersing players in a fairytale-like atmosphere.

The main characters of the slot are the three playable avatars: Sam (the master builder), Mandy (the charming builder), and Igor (an unlockable character). These characters serve as both protagonists and wild symbols in the game. Other characters include various princes and princesses who appear during the Royal Wedding feature.

Castle Builder II is a sequel to the original Castle Builder slot, which won the EGR award for best game in 2013. The predecessor introduced the unique concept of building castles as part of the gameplay. This sequel expands on that idea, offering more kingdoms, characters, and features.

Core Game Mechanics

Castle Builder II is played on a 5-reel, 15-payline grid. Before starting, players choose one of the available avatars, each with unique skills affecting gameplay. The game's main objective is to collect building materials (wood, bricks, granite, and iron) by landing wins with these symbols.

As players spin the reels, they accumulate building materials in a meter. Once the meter is full, a part of the castle is constructed. The game progresses through different kingdoms and levels, with players building multiple castles across 15 kingdoms.

The base game includes standard slot mechanics with various symbols, including the chosen avatar as a wild symbol. The paytable features themed symbols such as crowns, treasure chests, gold bars, and rings, alongside the building material symbols.
