This dataset was contributed by [Marco Cognetta](https://github.com/mcognetta). The original archived repository describing the project can be found here: https://github.com/mcognetta/lichess-combined-puzzle-game-db
## Background
> This contains every puzzle from the [Lichess Puzzle Database](https://database.lichess.org/#puzzles) joined with their games from the [Lichess Game Database](https://database.lichess.org/#standard_games). The puzzle data was pulled in September 2022. There are 2,969,948 puzzles in total. The game info was pulled from the [Lichess API](https://lichess.org/api) with [every flag enabled](https://lichess.org/api#tag/Games/operation/gamesExportIds).
## Format
>The database is given as a single `bzip2` compressed [ndjson](http://ndjson.org/) file. Each line contains a JSON object with two top-level fields: `game` and `puzzle`. The `game` object contains the entire JSON dump of the game information from the [Lichess API call](https://lichess.org/api#tag/Games/operation/gamesExportIds) with every flag enabled. The `puzzle` object contains all of the information from the puzzle database entry, with the field names being taken from the [csv headers](https://database.lichess.org/#puzzles). That is, you can expect the following fields in the `puzzle` object (though they are not necessarily all populated): `PuzzleId`,`FEN`,`Moves`,`Rating`,`RatingDeviation`,`Popularity`,`NbPlays`,`Themes`,`GameUrl`,`OpeningFamily`, and `OpeningVariation`.
>
>The games and puzzles are joined by the game id (`id` in the `game` object). The matching `id` is extracted from a puzzle's `GameUrl` field. Note that `PuzzleId` and `id` are unrelated.
