Frequently asked questions
Common questions about the reduced wheel 7 of 40 for Lotto
The reduced wheel contains 6 combinations (tickets) — 14% fewer than the full wheel (7 combinations for 7 of 6). Each ticket matches the Lotto rules: 6 numbers out of 40.
Guarantee 5 is the minimum number of matches on a single ticket that the wheel ensures if any 5 winning numbers are among your 7 picks. In that case, at least one system ticket is guaranteed to contain all 5 of those matches.
Only the full wheel of 7 numbers (7 combinations) guarantees the jackpot. The reduced wheel trades that 100 % guarantee for a 14% ticket reduction: it guarantees at least 5 matches on one ticket whenever any 5 winning numbers fall within your 7 picks. The jackpot becomes a strong chance rather than a certainty.
Total cost = 6 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 Lotto draw. On average, the 7-of-40 wheel with guarantee 5 is roughly 14% cheaper than full coverage.
