What is the name of the game where you start with 1 finger pointed on each hand and your opponent does too? You point one of your hands at one of your opponents hands and they hold up the sum of that hand and the hand you pointed with. If that sum is greater than or equal to five then that hand is out of the game, last player with a hand wins. Also isn't there cases where you can switch fingers to an closed hand? What are the rules on that?

In my 7th grade class, we played if it was equal to 5. If it was more, like 6, that would be 1 because you subtract five. We didn't play switching to a closed hand, so I don't know. We just called it the finger game.
Reply:In my school they call it The Fingers Game. I have no idea how it's played or anything cause I honestly don't give a crap about it, but, eh.
