Mostly my hams just love exploring!

I give them a playpen and let them go crazy and explore boxes with things hidden inside or stuffed with bedding or Woodshavings.

I make sure there's tubes and seesaws and crinkle tunnels to run through, different levels so they can climb, holes in random places for them to crawl through and investigate some more.
Very little human interaction involved but I try to do a swap around.
Gloria is pretty active so I let her burn off energy in the pen while I cuddle a less energetic hamster, then we do a switch, Gloria comes for calmer cuddles while my other ham gets to poke around the playpen.
Both hams go back and I do a repeat with a different pair of hams.
