In 1933, Rockingham was renovated and reopened. With its scenic placement and high quality of racing, Rockingham quickly became known on a national level. Immortal thoroughbred horses, such as Seabiscuit, Discovery, and Brass Monkey were three of the more notable racers campaigned at "the Rock".
Rockingham contributed to the well-being of the state of New Hampshire. Tax dollars paid from the track were immeasurable, and uncountable New Hampshire residents were employed at the track.
1980 marked a sad event for Rockingham when a fire destroyed the grandstand and severely damaged the clubhouse. Through new management, the Rock was opened yet again in 1984 with a state-of-the-art clubhouse. A turf course was installed in 1986 and after full-card interstate simulcast was allowed in 1991, a sporting club and family pavillion were added.
Rockingham now offers simulacasted racing from around the country, bingo and poker. Casino action games now available at Rockingham include; Texas Hold 'Em Poker, Blackjack, Roulette, Boston 5 and Let it Ride.
