dsh-game-center: Play mini-games in a panel

dsh-game-center is a plugin maintained by stallenlu for the DeepSeek Harness panel. It centralizes mini-games into a single interface, allowing gameplay to start directly in the same window upon clicking. The plugin includes built-in Tetris and "Cops and Robbers." The article details its system requirements (DSH 0.2.1-rc.5, Node >= 22), official installation commands, controls, and difficulty settings (saved per game) for the two games, as well as the method to extend the GAMES registry. Additionally, it explains the verify.mjs self-check script that operates independently of Harness, and notes that the plugin runs with the current DSH process permissions, advising users to check the source code and MIT license before installation.
