Shorter odds are not automatically better value — shorter-odds games pay smaller top prizes. Cost per unit of chance (price × odds) is the cleanest single comparison.

Tax on winnings in Thailand

Government Lottery Office prizes are effectively income-tax-free but carry a 0.5% stamp duty on winnings (1% for charitable draws), collected when the prize is claimed. Winners keep the rest of the prize with no further Thai tax to pay.
