Historical Conquest play mats help teach players the layout of the game, track Morale points (in order to win), keep cards from slipping and getting scratched, and making any surface much more flat and easier to play. Imagine playing this game on your bed, in the grass outside, or on a rocky terrain. Each mat is 14” x 24”, constructed with a bright polyester cloth surface and dense black open cell sponge rubber with a non-skid bottom that grips surfaces, thin enough to be able to roll or fold for storage.Plus the designs are really aesthetically pleasing (COOL!) too.
