OpenTafl is a free implementation of that old Norse board game, hnefatafl.
The OpenTafl server at intersect.manywords.press is currently running OpenTafl v0.4.7.0b, mostly compatible with client versions from v0.3.3.3b onward, and fully compatible with versions v0.4.6.3b onward2.
Please note that versions of OpenTafl prior to v0.4.4.3b suffer from a bug which causes undefined behavior when playing Copenhagen games. Before reporting strange behavior in such games, please attempt to reproduce it using v0.4.4.3b or later.
Please report bugs here.
