For this competition you're asked to write "fiction that is written to be read/played on digital devices." It seems that it's not quite as simple as writing a story and saying it'll work on a Kindle, because they want the piece to be 'born digital'.
There's a £300 prize for each category (including a Welsh language prize). Anyone may enter work in English or Welsh ... or HTML, Flash, or whatever the heck Twine is. You can attach your work or bung it on a cloud.
I'm beginning to feel like a Luddite. An old Luddite.
