Lotteries, scratchcards and bingo
What's the best scratchcard to buy based on prizes still available?
Direct answer
Use official scratchcard prize inventories AND the number of unsold tickets, if both are available. A remaining top prize alone cannot establish that a ticket has good odds.
How to use this answer
The best next step depends on the user’s circumstances. Start with the direct answer above and use the listed source or product details where they apply.
Compare remaining prize inventory and tickets outstanding if the lottery publishes both; remaining jackpots alone cannot establish your odds.
Use the published game matrix and prize rules for the exact lottery or scratchcard. Identical tickets, rollover jackpots and claimed win patterns should be assessed using probabilities rather than intuition.
