TUOLUMNE CITY -- A 66-year-old grandmother from Waterford invested $40 in a Black Oak Casino $5 slot machine and left with $1.75 million, the casino announced Friday.
Casino spokeswoman Rachel Pitts said the woman exclaimed, "I didn't believe it!"
The big winner requested anonymity, Pitts said.
She also quoted the woman as saying: "I just stood there and didn't say anything. I just couldn't believe how much it really was."
