At Interlock, you build the most extraordinary structures and make sure that no outlet or plug is left in sight. A challenge booklet is included and here are many different challenges that provide hours of fun. Each block is numbered and has a plug and socket in a unique location. You build shapes by plugging each plug into an outlet of the next piece. When the puzzle is solved, each plug fills an outlet and the completed shape has no visible plugs or outlets. So what are you waiting for? Choose a block and start plugging!
