+12 =5 −8
The record the way chess players say it
Wins, draws and losses are written “+12 =5 −8”, and the percentage reads in points: a win is worth 1, a draw ½. It is not a win rate.
-
- White
- Black
White or Black, straight away
The colour is noted before the result, and “Next game” or “Next round” takes the other colour. Your score with each colour is the first card of your statistics.
-
- Classical
- Rapid
- Blitz
- Bullet
- UltraBullet
- Correspondence
6 time controls, from classical to correspondence
The base time and the increment are noted as two numbers; the exact time control of inter-club matches, 40 moves in 1 h 30 then 30 min, keeps its wording. The time control also picks the Elo that applies to the game.

26 openings, and your own
From the Sicilian to the Ruy Lopez, with the ECO code if you want it. The list is open: an opening that is missing is created while entering, and your score reads with each colour.

1,678
Your Elo, time control by time control
Classical, rapid, blitz, each with its curve: the FIDE and FFE ratings, the ratings of online platforms and those of other federations. An estimated rating, such as “1,399 E”, is recognised and left out of the Elo gaps.
-
- Wins over higher-rated
- Losses to lower-rated
Your Elo against theirs
The opponent’s Elo is fixed on the day of the game: your wins against higher-rated players, your losses to lower-rated ones and your score by 100-point band of gap are read without recalculating anything.

- Checkmate
- Resignation
- On time
- Draw by agreement
- Repetition
- 50-move rule
- Stalemate
- Insufficient material
- Abandoned
- Timeout vs insufficient material
10 ways a game can end
Checkmate, resignation, on time, draw by agreement, repetition, stalemate… Choosing an ending that gives a draw offers the draw as the result, and your statistics show how your wins and losses are decided.

Round by round, with the division, the board, the points, the final standing, the Buchholz, the performance and the Elo change. These official results are copied in: the logbook does not recalculate them.

Tap a bar, a slice or a point: the games behind it open up. And every figure says how many games it is based on.
The tournament, the time control, the colour
A date and the result are enough. The tournament and its round, the time control, “Online” and the colour are touched straight away; the end of the game and the opening are filled in afterwards, if you want.
1 · ½ · 0- The round, from round to final, play-off or tiebreak, with its number.
- The time control: classical, rapid, blitz, bullet, UltraBullet or correspondence.
- “Online”, yes or no: a club blitz and an online blitz do not compare.
- White or Black with one touch; “Next round” keeps the tournament, the time control and the venue, and takes the other colour.
Your games, session by session
Each session gives its record the way players say it, and each game carries its opponent, their Elo, colour, time control and opening. “By tournament” gathers the games of each tournament with its record sheet: points, rounds, final standing, performance and Elo change, copied from the official results.
+1 · =1 · −1- A dot per game: 1 in green, ½ in grey, 0 in red.
- The session sums up as “3 games · +1 · =1 · −1”, with its venue.
- White or Black, time control, opening and “Official” as labels; the opponent’s Elo next to their name.
- Season from 1 September to 31 August, labelled “2026-2027”.
The board and the screen, side by side
A game played online is noted like the others, with the platform’s rating. Each time control is separated depending on whether it is played on the board or online: a club blitz and an online blitz do not compare.
Chess960 and the others
Chess960, Crazyhouse, King of the Hill, Atomic, Horde and their neighbours have their place in the list, with their rating when the platform gives one.
