My hamster keeps running around his cage digging at corners?

[millllstone]

I just got my hamster Rupert yesterday and he's been digging at the corners of his cage a lot, it's a 20 gallon tank, he has a wheel and a hut and water and just the basics, so I put him in his ball for a bit and put him back but he keeps digging sometimes, should I be worried? Is he bored or something? I'm not sure what exactly I should do to help him and I don't want him to be bored or stressed

He's new, he's just exploring. Give him some time to settle in and he'll calm down.

he is just testing the cage to see if he can get out,
