Help!! I’m Bored During Work?

I work for cricket doing tech support over the phone im going to be working 12-14 hours a day when summer starts i’m almost 18 years old, and I need something to do all day. Internet is not allowed even though we do it any way but then we risk getting fired and even that gets boring there are no electronics allowed on the floor so im just looking for something to do I already have an Rubiks cube and books are impossible to read becuase sometimes there are to many calls i need something hands on.Thanx
