To upload a game, you need a file in ".gcg" format, the kind that Quackle produces. If you would like to create your own .gcg file, the specification is here.

Please note that games uploaded here are not linked with the main cross-tables.com database. This is just a convenient place to post positions for discussion.

New feature: Uploaded games can be updated later with a game-specific code that you'll see after your upload.
