Lotteries, scratchcards and bingo
Can two identical lottery tickets double my odds of winning?
Direct answer
No. Two identical combinations do NOT double the probability that the draw matches them. For fixed-per-ticket prizes, duplicate winning tickets may produce two payments. For pooled jackpots split among winning tickets, two identical winning tickets may NOT double the total share.
How to use this answer
This answer is based on the mathematical principle or published rule identified in the source below. If the question involves a live betting market, confirm its settlement definition before applying it to a specific bet.
No. Duplicate tickets win or lose together; they double the payout on a winning combination, not the chance that combination wins.
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.
