Q-BA-MAZE: Multi 92 Piece Set

Is your kid outgrowing her Duplos? Level her up to this marble maze system for a more interactive left-brain workout that is endlessly entertaining. In the box you’ll find interlocking pieces and a baggie of marbles. Follow the easy diagram in the instructions to set up a base for your maze, and from there, the sky’s the limit (literally!) Build winding staircases, switchbacks, and perilous drop-offs and watch your marble go. You can also find blueprints for fan-designed mazes at the Q-BA-MAZE website, though a parent or older sibling may need to translate the schematics. (MindWare, $40.72)
