About & methodology
Bon Gratteux tracks Loto-Québec scratch ticket prize claims and estimates the remaining value of each game, updated daily.
How the odds are calculated
Each day we read Loto-Québec's prize-claims page (how many prizes of each tier remain) and the scratch games listing (ticket prices). The headline number is the remaining expected value per dollar: the value of the prizes still unclaimed divided by the estimated number of tickets still unsold. As low-value prizes get claimed faster than the big ones, a game's remaining value can rise.
Official rules vs estimates
When a game's official rules PDF is available, we use its exact figures — total tickets printed, theoretical payout ratio, and the cash lump-sum value of any "win for life" prize. Games tagged "Estimated" had no rules document, so their print run is approximated from the prize structure and an industry payout ratio (~58%).
Data & updates
All data comes from Loto-Québec's public pages and official rules documents. Figures reflect the most recent daily scrape; claim counts can lag real life.
