Lotteries, scratchcards and bingo
Can two people win bingo on the same ball?
Direct answer
Yes. A simultaneous valid call can trigger shared prize rules, subject to the venue's published procedures.
How to use this answer
The principle is supported by the referenced rules, but a different operator or market can apply a different settlement condition. Treat the named provider as a specific example, not as a universal betting rule.
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.
