Quarto is played on a 4x4 board. There are 16 pieces, each of which has four attributes: Tall or Short Round or Square Dark or Light Flat or HollowPlayers take turns selecting any of the available pieces. Once a piece is selected, the player gives the piece to his/her opponent who plays it in any of the available positions on the board. The winning player is the first player to create a row or diagonal which contains any four pieces that share a common attribute. (ie: 4 dark pieces or 4 short pieces, 4 round pieces, etc).The winning player need not have played all four of the winning pieces. He/she need only to place the final piece. Sounds easy? Good luck!Enjoy!
