In 1968, John Edwards was visiting a friend in the United States and came across a copy of Avalon Hill's Akrika Korps.

Edwards took the game home and, not knowing any other wargamers, played it solitaire for several months.

[1] Edwards designed several other games which were also licensed for sale by Avalon Hill, including War at Sea (1975) and The Russian Campaign (1975).

Other games published by Jedko include an Australian edition of TSR's Dungeon!, Alan Jones Formula 1 Grand Prix Racing Game and Basic Training, an introductory wargame between World War II Australian and Japanese in New Guinea.
