What is Super Lotto 638?
Super Lotto, called Power Lotto or Weili Cai in Taiwan, is the island’s biggest jackpot game, run by Taiwan Lottery. Players pick six numbers from 1 to 38 in the first area and one number from 1 to 8 in the second. A bet costs NT$100 and draws are held twice a week, on Monday and Thursday. Matching both areas wins the jackpot at odds of about one in 22 million. During the Lunar New Year period the jackpot is often boosted with extra prize money.
How Super Lotto 638 works
- Pick six different numbers from 1–38 – your own favourites or a random Quick Pick.
- Add one bonus number from 1–8. It is drawn from a separate pool, so the same value can appear in both parts of the result.
- Check your line once the numbers are drawn – only which numbers match counts, not their order.
- The top prize needs all six main numbers plus the bonus number; smaller combinations win lower prizes set by the operator.
Your chances in Super Lotto 638
The draw can produce 22,085,448 different results, which means the jackpot odds for one line are 1 in 22,085,448. Lower down the table the picture changes quickly: a result of six main numbers without the bonus turns up about once in 3,155,064 lines, and at least three correct main numbers about once in 26 lines.
In Asia, Super Lotto (Daletou) (1 in 21.4 million) has better odds and Grand Lotto 6/55 (1 in 29.0 million) is harder. Compared with US Powerball, the jackpot is about 13 times easier to hit. Among the 88 lotteries on this site, Super Lotto 638 ranks number 51 for jackpot odds, where number 1 is the easiest.
Playing two lines in two draws every week – 208 lines a year – you would wait on average around 106,180 years for one jackpot, so the jackpot is something to dream about rather than plan for.
Super Lotto 638 generator, odds table and demo
Start with the generator: it produces random Super Lotto 638 lines in the correct format, from one line to ten, and you can copy them in one click. Next to it you will find the full odds table and a demo draw you can repeat as often as you like. In the demo you also choose the bonus number from 1–8, exactly as on a real slip.
The simulator goes further: ten years of two lines twice a week means 2,080 lines, and on average about 75 of them would match exactly three main numbers while the chance of a top prize in that time is only about 1 in 10,618. No generator can improve the odds – every combination is equally likely – but it saves time and avoids popular patterns such as birthdays.
