Kriegspiel (the card game) is the worlds fastest (and easiest to learn) war game. The game teaches anyone the basics of card war game tactics in a way that is fast and fun.
The game modifies Rock-Paper-Scissors to Infantry-Cavalry-Artillery and adds the basics of the old card game, "War" to the concept. Players each play one card, facedown, at a time, and the winner takes the trick. The player with the most tricks at the end of the game is the winner. Due to game construction, there is always a winner, never a tie.
Kriegspiel, the card game, is the latest in the Warcoach Games "10 Minute War Game" series.
