Geomorphic mapboard

A geomorphic mapboard is a game board that can be configured in different ways and reused to create different playing surfaces. The concept was introduced in "PanzerBlitz", though the number of configurations was low. Many tactical wargames use them, and they also appear in "Robo Rally", "Magic Realm", and occasional other games.

The mapboards are made geomorphic by using identical features along the edges of the maps, so that any two may be paired.

The concept is embraced by "Advanced Squad Leader" (ASL), which has 60+ geomorphic mapboards as of 2006. ASL increases this flexibility with the addition of "overlays" to permit further changes to the playing area.
