How the level works

Your level is how well you play, from 0 to 10. It starts at 0 and climbs as you play; it can go down after a loss, because it is a measurement, not a reward.

What counts

Finished games of five moves or more against the engine, on Lichess, and with a friend when you are both signed in — those our server referees itself. Engine games with a move taken back, and games played on from a famous position, do not count.

The scale

The engine's rungs sit on it. Beat a rung regularly and that is your level.

Why it climbs

What is shown is what you have proven: our best estimate of your strength, less the doubt still in it. Every game shrinks the doubt, so a new player's level rises as they play, towards their real strength.

The ceiling

Games in your own browser can take a level to 7.00 at most, until you have played five rated games with friends.

The level board lists public players with ten rated games or more. More in Help.

How the score works

The score only goes up: the more you play, the higher it gets. Points come from three places.

Playing

Every finished game of five moves or more earns 10 points (5 if it was short). A draw adds half a win's bonus, and a win adds the bonus: against the engine, the opponent's Elo ÷ 40 (20 for the 800 rung, up to 75 for the full engine), 25 on Lichess, 15 against a friend. The first 20 games of each day count.

Practice

3 per puzzle solved, 5 per daily game won, 5 per lesson, 4 per mistake of yours learned, and 1 per master move guessed.

Likes

5 for every like another player gives one of your games, up to 10 likes per game.

The level is separate, and it can go down. It measures how well you play; the score measures how much.

Every finished game is replayed on our server before it counts, and only players who chose a public profile appear here. More in Help.
