Math game gets popular in Singapore Pri School

Raynor introduces me to the game. First, players stick out their hands with two index fingers. Player take turn to hit each other’s finger with theirs, every hit sum up the numbers of finger on the receiving side, when it reaches five, a hand is play out. Last player with finger left wins the game.

Player can uses one turn to hit his/her own finger, killing own self or equally distribute fingers among 2 hands even if he/she is left only with one.

This is a quiet game involves simple math, fast reflexes and strategy thinking, fun and exciting. As many as 4 to 5 players can participate for increase fun.

Raynor said the game was “Chopstick”, I rather it is name “Strategima” from TNG.

Anyone can shed some light on this game.

Update: Tstar says,
"This game isn't new... i played it when i was in primary school... and that was some 10 years ago. "

Thanks! still this game is quite good for pri student, it is like a carrot soup for the brain.
