Overview
Zig Zag Ancient Greeks was an educational game originally published by Longman Logotron and BBC Worldwide in 1996 for RISC OS systems. The object of the game was to complete a number of tasks related to life in an Ancient Greek town. The player's character wanders around an open area, entering locations where the tasks are situated.
Since there were many tasks to perform, the game provided an option to save progress to a file and load it again later. This page describes the format, based on the original notes for it.
