There are tons of options out there for retro gameplay, but we are particularly taken with this teeny handheld, styled after the classic GameBoy.

Firebox are offering three versions of the device, each with a different Nintendo title, so with one of these on your keyring, you'll never be stuck for something to do with your thumbs at quiet moments.

The games available are Super Mario Bros, Donkey Kong Jr and Mario’s Cement Factory, on sale now for a tenner each.
