Understanding Historical Horse Racing (HHR)
Historical horse racing terminals are the primary form of electronic gaming in Kentucky. To the untrained eye, these machines look exactly like traditional slot machines. They feature spinning reels, colorful themes, and bonus rounds. However, the underlying math works differently than a standard slot. Traditional slots use random number generators to determine if you win. HHR machines use the results of actual, previously run horse races. The names of the horses and the dates of the races are hidden to keep the game fair. When you press the spin button, you are actually placing a wager on those past races. The machine then translates those racing results into the reel combinations you see on the screen.
