The racino is owned and operated by Harrington Raceway, Inc., which is majority-owned by the Delaware State Fair, a non-profit organization.

[19] Instead, a $1-million project was undertaken to build an enclosed clubhouse and make enhancements to the grandstand, including improved heating.

[21] Attendance and betting at Harrington dwindled steadily starting in the 1970s, as part of the overall decline of the horse racing industry.

[27][28] In 1994, Delaware legalized slot machines at horse tracks in an effort to save the racing industry.

[35] The $10-million facility had 35,000 square feet (3,300 m2) of space with 500 slot machines, a simulcast wagering parlor, and a buffet restaurant.

[3][9][37] Harrington Raceway bought Gtech's stake in the slot parlor joint venture in 2004 for $12 million.

[40][41] As part of the project, the Midway Slots name was dropped in 2007 and the entire property became known as Harrington Raceway & Casino.

[43] The expansion was completed in 2008, adding a new restaurant, lounge, coffee shop, high-stakes gaming areas, and an expanded buffet, and increasing the number of slot machines in the casino from approximately 1,600 to 2,100.
