Frequently asked questions
Common questions about the reduced wheel 9 of 31 for Dia de Sorte
The reduced wheel contains 16 combinations (tickets) — 56% fewer than the full wheel (36 combinations for 9 of 7). Each ticket matches the Dia de Sorte rules: 7 numbers out of 31.
Guarantee 6 is the minimum number of matches on a single ticket that the wheel ensures if any 6 winning numbers are among your 9 picks. In that case, at least one system ticket is guaranteed to contain all 6 of those matches.
Only the full wheel of 9 numbers (36 combinations) guarantees the jackpot. The reduced wheel trades that 100 % guarantee for a 56% ticket reduction: it guarantees at least 6 matches on one ticket whenever any 6 winning numbers fall within your 9 picks. The jackpot becomes a strong chance rather than a certainty.
Total cost = 16 tickets × the ticket price. The current ticket price and final total are shown in the boxes above on this page — values are taken from the latest Dia de Sorte draw. On average, the 9-of-31 wheel with guarantee 6 is roughly 56% cheaper than full coverage.
