One popular game to play with your hamster is to create an obstacle course for them to run around in. Toilet paper rolls, PVC pipes, Legos and other household items are great materials to create a course with.
Arrange the tubes so that the hamster can run between them easily. Hamsters love to burrow, so adding some shredded newspaper for your furry friend to dig through will satisfy their curiosity and is more entertaining to watch. Try putting a treat in the paper for extra incentive. Hamsters tire quickly, so try to limit play time to 10 or 15 minutes.
