Documentation: Time Controls in Custom Challenges

I was asked in a PM to explain the different time-controls. I thought I’d share my explanation of the different controls here for re-use:

  • simple time controls set a per-move clock. So if you set this to 25 minutes, the clock will be reset to 25 minutes each time a player has to decide upon a move.
  • absolute time controls set a per-game clock. So this is like simple time controls except that the clock is not reset for each move.
  • canadian time controls set a per-N-number-of-moves clock. So you have a set time for, say, every 10 moves. But the clock is reset for each 10 move period.
  • byo-yomi is like the absolute time control except that once your main time expires you go into byo-yomi periods. These are a fixed number of fixed length periods. If you move before a period expires then it is reset to the full period. If you let a period expire it is lost forever.
  • fischer time controls are a per-game absolute clock with a per-move increment added after each stone. So there may be a 10 minute main time with a 10 second increment. Well, because of the increment, if you move within 10 seconds your time may actually increase per-move, allowing you to dig yourself out of time-trouble.

I think the person who contacted me was using simple time controls but expected absolute time-controls. I was certainly surprised by some of the names - have these just not been looked at for a long time, perhaps?

Thanks for the explanation. I’ve just started playing using the “Normal” button on the Quick match finder. I’ve been wondering what my speaker says when it goes to “byo-yomi.” Then, I wonder if I need to panic as it counts down from 10. Now, I think I understand it.

Is there a FAQ on this site? I’m really enjoying the game, but it takes a little searching to find the help I need.

There’s a wiki on the github

The wiki isn’t necessarily complete but can be contributed to :slight_smile:

The documentation and faq (near the bottom) in the hamburger menu, accessed at the top left of the site brings you to it. Although I think the hamburger menu is very often overlooked. I don’t really use it myself unless searching for something or changing settings.
