It's almost time for another Sandpit - an evening of new games at the Southbank Centre. And we've got a load of games that we're going to be playing there, and we think they're going to be really lovely. But we'd like to try out a few of them in advance, just to see if there are any last-minute tweaks or twists that would make them even more fun...

So, we're trying a few of them out at the Hide&Seek office in lovely centrally-located Farringdon, on Wednesday 23 May (yes, that's THIS WEDNESDAY). There's a bit of running around, a bit of shouting, a bit of plotting - a game about arguing, a game about encouraging your team through clever cheers, a game about new rules and voting and balls, and a game about balloons and big fans.

If you'd like to help us test the games out, do come along! There'll be some biscuits and juice and beer and so on, plus hopeful wide-eyed game designers hanging on your every word.
