There were other winners of small prizes as well, in Friday's drawing. There was a total of 1,702,748 winners at all other prize levels, according to the Mega Millions web site.
"Fifty-three tickets across the country matched four white balls plus the Mega Ball to win the game's third prize. Ten of those are worth $30,000 each because they included the optional Megaplier (a $1 additional purchase available in most states); the Megaplier for this drawing was 3X. The other 43 third-tier winning tickets are worth $10,000 each," Mega Million's press release stated.
