How the Thai Government Lottery is structured
The Thai Government Lottery is drawn twice a month, normally on the 1st and the 16th. Each ticket carries a six-digit number. Alongside the big prizes for matching all six digits, there are smaller prizes tied to parts of the number, including the last two digits and three-digit prizes for the first three and last three digits. This is why many players talk about 'two-digit' and 'three-digit' numbers.
This article is for information and entertainment only. Lottery outcomes are random; no method or app can predict or improve the chance of a particular number being drawn. Play only if you are of legal age where you live, and only with money you can afford to lose.
How many 2-digit and 3-digit numbers exist
Two digits, each from 0 to 9, give 10 × 10 = 100 possible endings, from 00 to 99. Three digits give 10 × 10 × 10 = 1,000 possibilities, from 000 to 999. Each specific number in a fair draw has the same chance, 1 in 100 for two digits and 1 in 1,000 for three.
Permutations: rearranging your digits
Players often pick a set of digits and want every arrangement. If you choose three different digits such as 1, 3 and 7, there are 3 × 2 × 1 = 6 orderings: 137, 173, 317, 371, 713 and 731. If two digits repeat, like 1, 1 and 7, there are only 3: 117, 171, 711. With two different digits for a two-digit number, there are 2 arrangements, like 37 and 73.
Building combinations from more digits
If you choose four different digits and want all three-digit numbers with no repeated digit, there are 4 × 3 × 2 = 24. Allowing repeats, the count is 4 × 4 × 4 = 64. With five digits it becomes 60 or 125. The numbers grow fast, which is the main reason people use a tool rather than writing them by hand. More numbers cover more outcomes, but each also costs a ticket, and the expected return of lotteries is below what you spend.
Front three, back three and last two
Because three-digit prizes are tied to positions on the six-digit ticket, it helps to think of your ticket as having a front block and a back block. A number like 482 is a different outcome depending on whether it appears in the first three positions or the last three. Two-digit prizes refer to the last two digits. When you list combinations, be clear which prize you are thinking about, because the same digits can mean different things in different positions.
A quick table of counts
From 2 different digits: 2 two-digit arrangements. From 3 different digits: 6 three-digit arrangements, or 6 two-digit arrangements if you take two at a time. From 4 different digits: 24 three-digit arrangements without repeated digits, 64 with repeats. From 5 different digits: 60 without repeats, 125 with repeats. These counts come straight from multiplication: for each position, count how many digits are still available.
Using a wheeler tool responsibly
A wheeler simply lists combinations so you do not miss or duplicate any. It does not change the odds of the draw. Set a budget first, then see how many combinations fit, rather than letting the tool decide how much you spend.
Frequently asked questions
Does a wheeler increase my chance of winning?
No. It only organises numbers; each number keeps the same chance.
How many arrangements do 3 different digits have?
Six.
How often is the Thai lottery drawn?
Normally twice a month, on the 1st and 16th, with occasional date changes for holidays.
What does allowing repeats mean?
It means digits can appear more than once in a combination, such as 113 or 777, which increases the number of combinations.
Is 000 a valid three-digit number?
Yes. Three-digit results range from 000 to 999.
