About & methodology
Bon Gratteux tracks the prize-claim status of Loto-Québec scratch tickets and estimates the remaining value of each game, updated daily.
How we do the math
The headline number for every game is the remaining return per $1: of all the prize money still unclaimed, how much comes back per dollar you'd spend buying tickets today. Here's the whole recipe, no mystery sauce.
- 1Start with the official rules PDF: how many tickets were printed, and how much prize money in total.
- 2Read today's prize-claims report to see how many prizes of each tier have already been claimed.
- 3Subtract: the prize money still in play, divided by the tickets we estimate are still unsold, gives the return per $1 right now.
- 4Compare that to the printed return. Small prizes get claimed faster than jackpots, so a game's remaining value drifts up or down over time.
Worked example
30X
Take 30X, a CA$30 ticket we track. Here are its real numbers as of the latest report:
- Total prize pool (printed)
- CA$18,439,250
- Prize pool still unclaimed
- CA$9,286,250
- Printed return per $1
- 73%
- Return per $1 now
- 71.3%
So buyers today get about 71.3% back per dollar — below the 73% the game was printed at, because the richest prizes have been claimed faster than tickets sold.
That's it — we're the friend who did the arithmetic, not the casino. No game ever pays back more than a dollar per dollar; we just show you which ones currently sting the least.
How the odds are calculated
Each day we read Loto-Québec's prize-claim status 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
We use each game's official rules PDF for its exact figures — total tickets printed, theoretical payout ratio, and the cash lump-sum value of any "win for life" prize.
