This is my favorite - it is fun, fast, and engaging. You should be familiar with the basic Pyramath game play.
1. Deal 5 cards between the 2 players like normal Pyramath
2. Deal 1 card face down to each player.
3. Place remaining deack at side of pile where both players can get to it.
Say GO! to start the game.
Each player is now going to build their pyramid as fast as possible by discarding to their own discard pile and pulling off the top of the common deck. There are no break - the rules are the same as the standard game - BUT both players are working at the same time. Whoever finishes first wins.
