Overview of the Thai Lottery Prize Structure
The Thai Government Lottery offers multiple prize tiers, giving every ticket holder several ways to win something beyond just the top prize. Understanding the full prize structure helps you know exactly what to look for when checking your ticket after each draw.
The Main Prize Categories
The GLO awards prizes across the following tiers in every draw. Note that prize amounts are set by the GLO and are subject to official updates — always refer to the GLO's official materials for the most current figures.
| Prize Tier | How to Win | Number of Winners (per draw) |
|---|---|---|
| First Prize | Match all 6 digits exactly | 1 |
| Adjacent First Prize | Number is 1 above or below First Prize | 2 |
| Second Prize | Match one of 3 drawn 6-digit numbers | 3 |
| Third Prize | Match one of 5 drawn 6-digit numbers | 5 |
| Fourth Prize | Match one of 50 drawn 6-digit numbers | 50 |
| Fifth Prize | Match one of 100 drawn 6-digit numbers | 100 |
| Three-Digit Prefix Prize | Match the first 3 digits of a specific drawn number | Multiple |
| Three-Digit Suffix Prize | Match the last 3 digits of the First Prize | Multiple |
| Two-Digit Suffix Prize | Match the last 2 digits of the First Prize | Multiple |
The First Prize: The Top Award
The First Prize is the headline prize — awarded to the single ticket whose six-digit number is drawn first. This is the prize most players dream of. Because Thai lottery tickets are printed in limited sets, the odds of any individual ticket matching this prize are relatively low, but not impossible.
Adjacent First Prize
A unique feature of the Thai lottery is the Adjacent First Prize. The two tickets whose numbers are immediately above and below the First Prize number also win a significant prize — though smaller than the First Prize itself. For example, if the First Prize number is 123456, then tickets numbered 123455 and 123457 each win the Adjacent prize.
Partial Match Prizes: Prefix and Suffix Categories
The Thai lottery rewards partial matches through its digit-based prizes:
- Three-Digit Prefix: If your ticket's first three digits match the designated drawn number's first three digits, you win this prize.
- Three-Digit Suffix: Match the last three digits of the First Prize number to win this prize.
- Two-Digit Suffix: Match the last two digits of the First Prize number for the smallest but most common prize.
These partial prizes mean that even if you don't win a top-tier prize, your ticket may still yield a return based on digit matching.
Tax on Lottery Winnings
In Thailand, lottery winnings are subject to withholding tax. The tax is deducted at source when you claim your prize. The applicable rate is set by Thai law and applies to prizes above a specified threshold. Lower-tier prizes may fall below the taxable threshold. Always check current tax rates with the GLO or a financial advisor before claiming a large prize.
Key Points to Remember
- Multiple prize tiers mean more opportunities to win per ticket
- The Adjacent First Prize is a distinctive feature of Thai lottery
- Partial digit matches (prefix/suffix) are rewarded separately
- Winnings above a set threshold are subject to withholding tax
- All prizes must be claimed within two years of the draw date
