As shown above, there are four matches laying in the form of a wine glass (so called) with a coin inside the glass.....by only able to move two matches, you got to get the coin outside of the glass but still keeping the same formation....
上面的圖中有四根火柴, 其排列有如一個紅酒杯, 而杯中有一金幣....你只能動兩根火柴的情況底下領那金幣不再在酒杯範圍內.....但那排列仍然要保留那紅酒杯的形狀.....
