Puzzlets ($100) is designed to teach preschoolers how video games are programmed. Using a board that connects to a computer or tablet, kids place puzzle pieces into the board to help the characters find solutions to their puzzles. So when you want the character to jump, you place the jump piece into the next available slot, and when you want him to run faster, you place the fast piece on the board. When strung together (like a code), the pieces instruct the characters how to move.
