Brain Builders combines 20 KEVA planks with a set of double sided puzzle cards. Each stimulating card features a 2 D challenge on one side and its solution on the other.

The 2 D cards show the design from different angles highlighting the front, side and overhead view and increase in difficulty from beginner to expert.
