ONE counter is for the PLAYER only and has a target of ONE.
When that ONE question is answered, and the target is reached, it disables the Questioner and for that player, and a Banner appears that says, “Go Get a Friend” - so the player is still in the game, but can go back and help a friend.
I made ANOTHER counter, which is Global and has a target of TEN.
When TEN people answer the last question correctly, the Game is over!
