After playing the game against you, let the kids play against themselves. Divide the class into two teams. Draw the game on the board and give each team three stars. Practice the English, then choose five kids from each team. Have them make two lines at the board.
Winners get one star.
Keep these five kids at the board until one team has won all the stars. This give kids different gos at the game, first move, last move, etc. Surprisingly, through the pressure of being up at the board, you'll get some classic losses. You can enforce a strict, no helping rule to make the game more interesting. Keep the same five kids and rapidly play until you've lost the first of your three stars.
