The mistake, which was just one digit, meant that the casino was unable to pay out the jackpot. However, the staff member entered her social security number incorrectly. She went to the cage to cash out her jackpot win.
The customer, called Cynthia Obie, told news outlets that she was playing a slot machine when she won the jackpot. The jackpot was voided due to a staff member accidentally inputting the incorrect social security number. The casino has publicly apologized to the customer.
The mistake voided a substantial slot machine jackpot. The MGM National Harbor casino in Maryland made quite an unfortunate mistake recently.
