剪刀，石头，布

I remember I start played 剪刀，石头，布 when I was at primary school. But, I'm so impress that Kaitkyn know how to play it, I believe Ah Mah have teach her since sometimes as she know exactly the rules of the game. I saw her played it with her Ah Mah 2 days ago, but she play with tricks, purposely response slow, so she able to win after Ah Mah.
