CLUSTER CHESS-PLAY-WEB · 101 ENTRIES · EARLIEST ENTRY 2014-08-26

Chess and variant board games

The cluster consists of digital chess and chess-variant games, mostly web-based, offering play against AI or other players, with some featuring 3D graphics, coaching, or unusual variants. Entry dates before the index start span from 2011 to 2026, but with only 14 dated entries, the timeline is too thin to discern a clear shape. Traction leaders by activity signal are CHESS-APP (7 stars), followed by 4dchess and ChessTrainer (3 stars each).

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
