24h HyperBullet tournament

BitChess Announcements

Yes, we know it's complete madness.

Not for the faint-hearted

What? A 24 hours long Arena tournament. Time control is 30 seconds, no increment.

Where? Right here on

When? 2016/10/15 at 9PM UTC. See it in your own timezone on the tournament page.

Who can enter? Everyone. Like everything else on lichess, it is free for all.

Is it a lichess Marathon? No, it is not. The Autumn Marathon happens one week later.

Do the top 100 get a trophy? No, since it is not a Marathon event.

24h of hyperbullet? Have you lost your mind? We can agree this event is indeed unreasonable. Fortunately, no-one is forced to participate.

I have more questions! Please see the event FAQ.

Stay healthy. Take frequent breaks. You can withdraw the tournament at any time, take a nap, then join again later with all your points intact.
