My boys are 4 & 6 years old, and they both LOVE this new 'mouse & cheese' game, as they like to call it. It has kept them entertained for hours. My 6 year old has fun setting up the mazes as depicted on the cards that came with the box - it's a challenge for him to set up something new, and see if he can get Colby to the Cheese. He's looking forward to his next playdate with a couple of his classmates so he can show them the fun ways to play!
