Triple double.. If 3 of your player's stats in a game has a double digit number.. Example, my player got 32 points, 10 rebounds, 2 steals, 14 assists, 6 blocks, 10 turnovers in a game..
As you can see, points, rebounds, assists and turnovers are double digits BUT turnovers are not counted.. So 3 stats have double digits.. Thats why it is called triple double..
