At Now Play This last year, we ran a game called Woodlouse (created by Jake Simpson and Pete Morrish). To play Woodlouse, you think of words (like “woodlouse”) that have more vowels than consonants. That’s it. If a word qualifies, it’s “a woodlouse”.

When we ran the game, we had a big piece of paper with some marker pens nearby. We put instructions out, and I wrote up a few sample words (in different coloured pens, with an unconvincing attempt at faking different handwriting styles). Then we invited people to write up any woodlouses they could think of.
