Frequently asked questions
Common questions about the reduced wheel 17 of 30 for 七乐彩
The reduced wheel contains 27 combinations (tickets) — 100% fewer than the full wheel (19448 combinations for 17 of 7). Each ticket matches the 七乐彩 rules: 7 numbers out of 30.
Guarantee 3 is the minimum number of matches on a single ticket that the wheel ensures if any 3 winning numbers are among your 17 picks. In that case, at least one system ticket is guaranteed to contain all 3 of those matches.
Only the full wheel of 17 numbers (19448 combinations) guarantees the jackpot. The reduced wheel trades that 100 % guarantee for a 100% ticket reduction: it guarantees at least 3 matches on one ticket whenever any 3 winning numbers fall within your 17 picks. The jackpot becomes a strong chance rather than a certainty.
Total cost = 27 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 七乐彩 draw. On average, the 17-of-30 wheel with guarantee 3 is roughly 100% cheaper than full coverage.
