Slot machines could soon make their way into New Hampshire’s gaming halls — if set at the same playing speed as historical horse racing machines.

Across many states with legal casinos, historical horse racing (HHR) machines have been a workaround for allowing slot-style gaming.

Unlike traditional slots, HHR machines let players bet on past horse races through a pari-mutuel system. In this system, players wager against each other rather than directly against the machine. These machines have a minimum five-second delay between plays, providing a slower pace than typical slot machines.
