Brain Builders offers a unique way of utilizing KEVA Planks. The set contains 20 planks and double-sided cards with stimulating puzzles. The puzzles feature 2-D designs to be transformed into 3-D structures, displayed from multiple angles. The card difficulty increases from beginner to expert, with the goal of replicating balance, proportion, composition, and geometry. If you suspect you solved the blueprint, flip over the card to see the solution—but don't peek first! Each build will challenge your patience and confidence as you scrutinize the design. From picnic tables to swans, put your creativity to the test and create 3-D structures with Brain Builders.
