All of the challenges in the 3d Challenge card set are unique to this set. They are the same type of challenges but do not duplicate challenges from KEVA Brain Builders or KEVA Brain Builders Deluxe.
The cards in the 3D Challenge Card set are larger (4" x 6") and the kit includes a plastic storage case. This set does not include any KEVA Planks. If you like Brain Builders, you'll like this set with more challenges to keep brains nimble.
