Rabcat launches a new slot machine Castle Builder II

Castle Builder II is a very unusual online slot developed by Rabcat, and it offers 15 paylines and 5 reels. This casino game features its high-end design and many interactive elements, so players need to complete different challenges to unclick further levels and increase their winning potential. They can play this innovative slot machine only for 15p per 1 spin on any compatible device.

First, it’s required to choose a special avatar before completing this casino game. Its reels are made of bricks, wood, iron ore, and granite along gold, rings, and treasures. Crowns are the most rewarding symbols because they multiply stakes up to 50 times. Kings are wild symbols and they substitute others.

Players need to collect different building materials by getting winning combos on their reels. They are collected into pallets, and when they’re fully loaded, special building blocks are formed. The more building blocks you gather, the closer you’re to completing this game and winning more. Check a special meter to track your game progress.

Free spins are triggered by scatters, and they help you boost a winning potential. Finally, the Bronze Cup Challenge feature asks you to land different building materials in pallets.
