Description

Joan Ginther was an American four-time lottery winner. She first won the lottery in 1993, when she won $5.4 million in Lotto Texas (equivalent to about $11.8M in 2024). Her next win came in 2006 when she won $2 million in the Holiday Millionaire scratch-off. Her third win happened in 2008, when she won $3 million from a Millions and Millions ticket. In 2010, she won $10 million, her largest prize, bringing her total winnings to $20.4 million. [6] According to mathematicians asked by the Associated Press, the odds of winning this many times were one in 18 times 10 to the power 24, [7] but this was apparently a miscalculation. [8] All of her winning tickets were purchased in Texas, and two of them were bought from the same convenience store in Bishop, Texas. [9] Prior to her death she lived in Las Vegas, Nevada and preferred to keep a low profile. [10]

Ginther died on April 12, 2024. [11]
