This site has some great little games.

A penny whistle for adults.

You can get adult Lego sets now . Or juggling balls?

My family (who live abroad) and I have been doing a virtual escape room at weekends. It's been great fun. There are lots of them online and some for one person as well as groups.

Look up The Happy Puzzle Company. I think it's called that or something similar. Loads of brilliant things on there.

One of those Wentworth wooden puzzles perhaps, where no two pieces are the same.....

A set of tangram pieces with a selection shapes to make (with solutions or maybe not!). You can make them out of card (any size square, join with various mid-point with ruler, see picture), and find the puzzles to make online www.tangram-channel.com

How old is your son? I have five adult sons who spend most of their free time watching films, tv and looking at their phone. I couldn’t imagine any of them doing puzzles or jigsaws.

Painting by numbers for adults is a great way of doing something absorbing while listening to the radio or music.

I would consider making a personalised origami hand game as you probably know a few good things to put inside that would amuse?! (Very light to post)
