Every Brazil game on this site, ranked by top-prize odds, with the tax rules and the regulator. All odds derived from the published rules.
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.
Federal lottery prizes such as Mega-Sena are subject to 30% income tax withheld at source on prizes above the exempt band (around R$1,900) — advertised jackpots are pre-tax and Caixa pays the net amount. The withholding is definitive, with no further income tax due on the prize.
90 days from the draw; unclaimed prizes fund federal education programs.
