Castle Builder II

If there was ever a slot machine game which took the online casino world by surprise, it would be Castle Builder. This Rabcat developed slot machine exceeded all expectations with its truly unique and entertaining style of gameplay. Now, Castle Builder II has arrived at online casinos, aiming to continue the excitement the original lay down. Castle Builder II is played over 3 reels and 25 paylines and can cost players anything from a floor bet of 15p per spin, right up to £30 a pop. With an RTP rate of between 95.5% and 97.75% (it increases as you play the game), there is good value for money to bag won in this game, with top prizes worth 50x your total bet in all.

Special features

Castle Builder II’s gameplay is much in the same vein as its predecessor, in that players are going to want to collect as many building materials as they possible can, in hope of building castles and setting up matches between princesses and princes. Players can choose to be Mandy or Sam in this game, although unlockable avatars do add an added sense of excitement to the game. The king himself acts as a wild symbol in this slot, and the best paying symbol in the game.

Additional features in the sequel include Bronze Cup Challenges, and Free Buildings Mode, which can see players win big prizes for completing pallets of building materials, and for building castles in 15 kingdoms.

Bonus features

Players who land 3 or more scatter icons on the reels of the game will trigger a free spin bonus round. Players will start the feature with 10, 15 or 20 spins, depending on whether they land 3, 4 or 5 scatters on the reels. Extra building materials can be won in this feature, whilst players who complete castles can try and win the hand of the princess to bag big cash prizes.


Castle Builder II doesn’t really build on the success of the first slot, although it does provide more of the same. Given that most players loved the original, they are likely to find the sequel slot very appealing, too.
