My informant remembers this game from being a kid, primarily in elementary school. The game begins with both players holding out their hands, each hand with only one finger extended, the rest curled into the hand. The players take turns choosing one of the opposing person’s hand to tap with one of their hands. When a hand is tapped, that player must extend an additional numbers of fingers on the hand equal to the number of the hand it was tapped with. So if a player has two fingers extended on his hand and taps the opponent’s hand, which has one finger extended, the opponent must extend two more fingers, leaving his hand with three extended. When a hand reaches exactly five fingers, it’s put away. If it goes over five (ex. it has three fingers and is tapped by a hand with three), the difference between the number it should have and five is how many it ends up with (from the example, it would now have one finger). The objective of the game is get both of your opponent’s hands to be put away. Also, when one of your hands has been put put away, if you have an even number of fingers on the other hand, you can “split.” That means you use your turn to tap your fists together and redistribute the number of fingers on one of your hands between the two evenly.
The reason my informant likes this game and remembers it fondly is because its making fun out of nothing; it doesn’t require any materials besides your hands. And it’s strategic and logical; by thinking it through, you can decide the best move and win by being smarter or more skilled than your opponent. My informant likes games of strategy like that and remembers that after being taught the fingers game at a very young game by peers, he realized his interest in strategy as well as his competitive urge. He eventually moved on to chess, which is still a big part of his life.
The game, to me, is interesting because it represents kids experimenting with things like logic and strategy at an early age. It makes problem solving fun; you have to think a lot to know how to win but then you’re rewarded with respect from your peers if you do.
