Using a MAGNETIC dart set, DO NOT USE A REAL ONE WITH SHARP POINTS - DO NOT DO THIS, use a MAGNETIC one. Place the board on a wall. Now blindfold one player and give them the darts, they get three throws of the darts, or nine darts in total to throw at the board. Then the next player takestheir turn. Whoever gets the most points wins.
