PlayStrategy is an open-source game server inspired by Lichess, extending the concept beyond chess to cover a wide range of abstract strategy games. Alongside numerous chess variants (including Chess960, Crazyhouse, Three-Check, and others), the server supports Draughts in multiple national variants, Go, Backgammon, Othello, Lines of Action, Shogi, and several others.

The platform offers rated play, tournaments, puzzles, and analysis tools for supported games. The interface is clean and familiar to Lichess users, with similar community features including forums, clubs, and broadcasts. Being open source, PlayStrategy is developed and maintained by a community of contributors.

PlayStrategy is entirely free with no premium tier. It is particularly appealing for players who enjoy the intersection of chess and other strategy game traditions, or who want to explore abstract games beyond chess in a single platform.
