Yes to both, scratch cards and both lotteries.  But if you play because you need extra money, you will waste time and money.  I do it because my GF enjoysw nit, and never had enough cash to do it previously.  So, sometimes sh selcts one set of numbers, and I do another set, and we see who can guess the most numbers.  So far, it is me with 4 out of 7, for as 40 yuan payback on a 4 yuan bet.  With scratch tickets, we have won 10 yuan prizes many times, once a 50 yuan price.  Again, we do it for fun, and it is not in perue of a fortune.  It is also cheaper than going to Starbucks for a cup of coffee and a pie.  We spend maybe 50 to 70 yuan per week on these two, and so far we are just about even.

I never tried that here, but I did buy one of those in L.A. last time I was there. I believe I won 5 dollars off of a 1 dollar card. That paid for my lunch that afternoon...

No but keep them in your wallet any way, they can be used as TP.

I buy lotteries sometimes for fun,but only once won 5 RMB.And actually i won nothing,as there were three friends with me at that time,they asked me to celebrate as that was the first time i won a lottery.So,i bought each of them an ice cream and then bought the other lottery only to win nothing.Compared with me,one of my friends was really lucky,he actually made a profit though he just bought lotteries for fun.One day when we were walking in the East Lake park in Wuhan,a bird shit on his clothes while flying away,my friend thought he was in bad luck,so he went to buy a lottery and turned out to win 50 yuan.He won 50 yuan again a few day later.And he won 10 yuan for many times.I was quite jealous of him.

5-10-20 kuai, but never the advertised 1500000RMB...
