Frequently asked questions
Common questions about the reduced wheel 42 of 43 for ロト6
The reduced wheel contains 644 combinations (tickets) — 100% fewer than the full wheel (5245786 combinations for 42 of 6). Each ticket matches the ロト6 rules: 6 numbers out of 43.
Guarantee 3 is the minimum number of matches on a single ticket that the wheel ensures if any 3 winning numbers are among your 42 picks. In that case, at least one system ticket is guaranteed to contain all 3 of those matches.
Only the full wheel of 42 numbers (5245786 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 42 picks. The jackpot becomes a strong chance rather than a certainty.
Total cost = 644 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 ロト6 draw. On average, the 42-of-43 wheel with guarantee 3 is roughly 100% cheaper than full coverage.
