Why are there different ratings in live chess?
Why are there different ratings in live chess?
Updated over a week ago

Live Chess has three different ratings based on different time controls:

  • Bullet rating - For games under 3 minutes.

  • Blitz rating - For games over 3 minutes but under 10 minutes.

  • Rapid rating - For games 10 minutes and longer.

We keep these rating separate because of the largely different skills involved in playing shorter or longer games.

The per-move bonus time (increment) is significant - not just the base minutes.

The system assumes an average game-length of 40 moves to estimate the total length of time available to each player; the result is what determines which rating is affected by a given time control:

A time control of 2 |12 therefore results in a Rapid (not Bullet or Blitz) game like so:

2 minutes + (12 seconds x 40 moves = 480 seconds) = 10 minutes

As a reference, here are some examples of presets available in Live:
