How do i keep my hamster entertained?

Well, some hamsters like to play with toys, you might want to check to see if there are any specially designed toys for hamsters available, or you can make your own toys.  I recommend picking a small flat toy that they can move around in their cage, and also some sort of sphere or ball they can chase or push around.  You might also want to make sure they have plenty of activities to keep them active.  Some people use an exercise wheel, or else offer them small amounts of food and play with them every so often, so they get a chance at some sort of game.  
I recommend picking one or two types of toys for your hamster, and then rotating them to keep it fresh and interesting.  Likewise, make sure you offer them the right amount of food to keep them active, and play with them every once in a while so they can have fun.  Also, make sure their cage is properly sized for them.  This might depend on the type of hamster you have, some hamsters really like to have a large cage to run around in, while others like to have a smaller space they can hide in.

Should I get him a play area, like those tubes that can connect like a puzzle?
Those seem like they might be good.  You want to make sure the play area is just the right size, that it can connect, and that the hamster can access all of it.  Those things seem like they’d do.  If you have the time and resources, I think having a play area would be good for your hamster.
Yes, you might want to check into those types of play areas.  They can help keep your hamster active, and they can also provide a fun challenge for the hamster to explore.  I recommend checking into whether your hamster likes that kind of interactive play, or if they might need a larger space to play in.
