Kingdom Builders are the only toys that combine figural play with role-play tools that unlock a magical world of adventure! There are multiple ways for kids to build the Hex Castle. There are targets and action bolts on the castle. If a target is hit, this will expose part of the castle. The action bolts open and raise different parts of the castle. King Hex is included and he transforms into a Hex Wrench to build and rebuild the castle. The Hex Castle encourages imaginative and creative play!
