WPF Rating
In various sports exist some kind of ranking. One example is in tennis with the ATP world ranking, another one in chess with the FIDE world ranking using the Elo rating system. We drafted a first version of a rating system for puzzle solvers. How the rating is computed, can be found at: WPF_Ratings_Synthesis.pdf

Furthermore we used the results of the GP 2021/2022 and the WSPC 2022 to get the current ratings of almost 900 solvers.
Current WPF ratings: Sudoku Puzzle

All rounds of the WPF Sudoku/Puzzle GP 2023 will be taken into account, as well as potentially other events. Updated ratings and rankings will be released on a regular basis.

Soon we will upload a similar rating for puzzles as well.
