Castle Builder Slots Review

Journey through medieval, fantastical kingdoms and stumble upon fearless knights and mighty kings. King Green has appointed you to build the most impressive castles for the fairest of all, the princess. Build your own kingdom!

Introducing Castle Builder, a slots game unlike any that you've experienced before. Become fully immersed in the amazing gameplay and graphics as you try to construct 35 buildings across three medieval realms. With 5 reels, 3 rows and 15 paylines, the opportunities to win on Castle Builder are plentiful.

Your Quest

To begin your construction quest for the king, you must first choose your coin size, ranging between 1p and £1. Castle Builder caters to players of all budgets and better yet, you can play with a small coin size but across a maximum of 15 paylines, so there is still plenty of opportunities to win big.

Once you've selected your coin size and the amount of paylines you'd like to play across, you can press the central spin button, or choose the option of multiple automatic spins in a row, so you can sit back and watch the reels spin and hopefully castles being built!


The symbols in the game include princesses, princes and kings, as well as the very important wild symbol - an architect! Each symbol is related to the game, including the building materials, and the more that land on an active payline, the more they're worth. More valuable building blocks will increase the value of your castle once completed.


We'd recommend playing with all 15 paylines active, because the building materials can only be gathered on them, so your chances are increased this way! This is the aim of the game afterall.

Play Castle Builder for a game that is quite like no other, in terms of its levels, narrative and gameplay.
