Crosby purchased his lucky $20 ticket from Quick One Stop on N.C. Highway 66 South in Kernersville.
He claimed his prize Friday at lottery headquarters in Raleigh.
Crosby had the option of taking the $4 million as an annuity of $200,000 a year for 20 years or a lump sum of $2.4 million. He chose the lump sum and, after required federal and state tax withholdings, took home $1,698,006.
The $4,000,000 Gold Rush game launched in August with three top prizes of $4 million and six prizes of $100,000. Crosby won the last top prize so the lottery will begin steps to end the game.
