gamble

Have you ever done any gambles? Horse race, Auto race, Pachinko, Mah-jongg, Cards(Poker). Some of them are illegal in Japan. I somethimes bet on a horse race but couldn't pay back money enouth. I don't like Pachinko taking much time. I've a bad imagine of Pahinko parlour. Everyone plays Pachinko smokes and get angly easily. I used to play Mah-jongg on the TV games. It was difficult for me to get its rules. How to make patternes of "Yaku", calcurate "Yaku"'s score.
