How we work
- We sell nothingWe are not a lottery, an agent or a ticket courier, and we take no bets. Nobody pays us for a verdict.
- Formats from the sourceEvery game's format is copied from its operator's own page, and each page names that source.
- Every number is checkedOdds are exact combinatorics, confirmed by counting every draw of smaller games and by two million simulated draws. See the methodology.
- Play for fun, not for moneyOn average a ticket returns less than it costs. If playing stops being fun, help is free.
