In 2008, Hnefatafl was revived by Peter Kelly in the island of Fetlar in Shetland, where the annual World Quickplay Hnefatafl Championships are now held each summer under the auspices of the Fetlar Hnefatafl Panel. The term "quickplay" refers to the time limit of ten seconds per move, marked by the sounding of a gong. The Fetlar rules were for some time the standard in international hnefatafl play, but have since largely been superseded by Copenhagen Hnefatafl, which builds on Fetlar Hnefatafl.
