Havoc: the Hundred Years War is a card game where players compete in a series of battles by recruiting soldiers to form sets (poker hands) to win victory points. The Dogs of War are used to retrieve soldiers from the battlefield or to draw extra resources. After 8 skirmishes a final battle ends the game and crowns a new king based on total victory points.
This is meant to refresh one's memory who has already played, but it has been a while. So that you can get on with playing instead of perusing the rules - expect for specific rules questions. Hope you find it useful!
