Student Instructions

Christmas Nim

This is a two-player game. Each player takes turns removing as many pieces (ornaments) as they like as long as the pieces are from the same horizontal row. Continue taking turns until all pieces have been removed. The last player to move a piece loses the game. Can you stick your opponent with the last piece? Keep playing and try to develop a strategy that leaves your opponent with the final move. Use the tool to chose the pieces you want to move. Use the tool over and over again to reset the game.
