Receipt and Taiwan Lottery


Does anyone know what's up with the three bonus numbers they've added to the receipt lottery? Do you win anything special if you get those numbers? Are they add-ons to the regular numbers? :saywhat:


If your last three numbers match those, you win NT$200. That's it. Good luck! :slight_smile:


Here they are:

Sigh. Only 13 more days till I find out if I'll be a multimillionaire or not. :wink:

Window for collecting prizes: April 6th to July 5th only!

Good luck! :slight_smile:


That game is such a complete scam. You can even prove it to yourself:

If you take the time you spend collecting and checking your receipts,
and divide that by the total prize amount you win...

You will find that playing the receipt lottery is equivalent to an NTD75 PER HOUR job.

Yes, some people win big. But you'd have to be a mathematical fool to think you stand a chance of being that person.


Only if you check your receipts very, very slowly. The expected winnings are about NT$1 per receipt.


It takes me about 10 minutes to check them. I win $200 every 2nd or 3rd time, and sometimes win $400 or $600. On average, in 6 months, I probably win $400. That's $800 an hour, plus the hope of winning the big one someday. And even if the luck runs dry, it's something I can do while listening to the news in the background, so I don't look at it as work.


I can't remember how much we've won in the last three years, but it is definitly worth doing. We got $4,000 once and regularly get $200.

Mildseven, feel free to send me yours - I'll check 'em. Or you could always put them in the charity boxes dotted around.


I have a whole drawer full of reciepts that I can't bring myself to throw away, but I'm too lazy to check for winners. They must go back at least six months.


On average 1$NT per receipt . um....

The last two lotteries I had about 100 receipts each time and no winners. So anyone feel lucky and willing to pay me 200$NT for the next 100 receipts ?


For 100 receipts and three different numbers for winning 200NT, you have about a 30% chance of winning 200NT, so the expected value of your 100 receipts is about 60NT. Anybody who pays more than that would be getting ripped off.


You're undervaluing your receipts. Lets see, for each of the 3 numbers:
3-digits, NT$200: 200 * 0.001 = 0.2
4-digits, NT$1000: 800 * 0.0001 = 0.08
5-digits, NT$4000: 3000 * 0.00001 = 0.03
6-digits, NT$10000: 6000 * 0.000001 = 0.006
7-digits, NT$40000: 30000 * 0.0000001 = 0.003
8-digits, NT$200000: 160000 * 0.00000001 = 0.0016
Total: 0.3206

(Note that you can't claim the 3-digit prize as well if you claim the 4-digit prize, so effective prize money in this calculation for 4-digits is actually NT$1000-NT$200 = NT$800, hence the slightly odd looking figures above)

For the big prize number:
8-digits, NT$2000000: 2000000 * 0.00000001 = 0.02

So the expected winnings for each receipt = 3 * 0.3206 + 0.02 = 0.9818
Or your 100 receipts are worth an estimated NT$98


David is right. I just considered the 200NT part.

I don't agree with the fine print, but my calculations were very similar.
0.316728 *3 = 0.950184 + 0.02 = 0.970184

So they are worth almost a dollar apiece.


Damn you Spock or Richardm you see I know how to play poker. I was going to make a killing (200$NT) selling my receipts. Now who is going to buy them? How am I going to retire to the life I so justly deserve?


Hardly ever won since they cut down the amount of winning numbers ... until this time: my biggest catch ever, 2,000 NT (or minus tax = 1992 NT).

One receipt was for an 85NT bagel breakfast at IS Coffee, and the other was a receipt my wife picked up off the floor somewhere!


Anyone have the numbers for the receipt lottery that happened on May 25th for months March and April?
