How cuddly a hamster is depends on hamster's personality. I have had hamsters that have been extreme cuddly and some hamsters have rather been on adventure, running on the floor or in the hamster ball, rather than cuddle. But in my own personal experience they are still very cuddly and enjoying when you pet them and cuddle with them.
I have had hamsters that have been like comedian's, i have had hamsters that have licked my nose, slept in my palm when watching tv and etc, over the years. They are cute just to look at. It is enough just to look at their cute little faces and when they loo at you..
I like the way mine played in the tunnels we built for her, it looked really funny the way she ran back and forth and doing some rolls forward through them. Besides that, I think they're really cute with their big eyes compared to their small heads!
