Ratings on ChessKid
ChessKid maintains two ratings for each account: a chess rating and a puzzle rating. These ratings are specific to ChessKid and are not tied to any official rating system. However, as a student plays more games, their ChessKid rating may begin to better reflect their playing strength.
Chess ratings
Chess ratings start at 800 and will go up or down based on wins and losses. How much the rating changes after each game depends on your current rating, your opponent’s rating, and how many games each of you has played. As you complete more games, your rating will generally change less dramatically than it does at the beginning.
Resigning before making a move (canceling a game before it starts) will cause your rating to drop.
Puzzle ratings
Puzzle ratings also start at 800 and change as you solve puzzles. Solving puzzles correctly will lead to more challenging puzzles over time.
