Horse racing is often cited as the most common example of pari-mutuel betting. But what about Historical Horse Racing, or HHR? At first glance, the term seems self-explanatory, but the concept is more complex than it appears. While HHR shares several key similarities with pari-mutuel betting, it also has notable differences.

Below is a simplified overview of how Historical Horse Racing works and how it compares with pari-mutuel betting.

What is Historical Horse Racing?

Historical Horse Racing (HHR), also known as instant racing, involves wagering on horse races that have already happened. However, that description only scratches the surface.

The races are anonymized by removing all identifying information. Bettors cannot see the race locations, dates or the names of the horses, trainers or jockeys. Still, enough data remains to allow players to make selections. Available information typically includes race conditions, odds and the horses’ past performance data.

Unlike live horse racing, HHR mimics the look and feel of a video lottery terminal or slot machine. Races may play out like slot-style games or simplified graphical presentations. They are fast-paced, usually lasting only a few seconds, and outcomes are determined by the results of the original races.

Historical Horse Racing vs. pari-mutuel betting

Historical Horse Racing and pari-mutuel betting share some foundational traits, but they also differ in important ways. Their primary similarity is that all wagers on a given outcome are pooled and used to pay both winners and the operator. As a result, HHR does not offer fixed odds, even though it blends elements of sports betting and slot machines.

Beyond that, the differences become more pronounced. Below is a summary of the most notable distinctions:

Information and skill

In HHR, racing information is intentionally limited to prevent bettors from identifying the actual race. While some analytical data is available, the role of skill is minimal.

In traditional pari-mutuel betting, players have access to comprehensive race information, including details about individual horses, trainers, jockeys and race locations. Data analysis plays a significant role, making skill a key component of wagering decisions.

Timing and speed

HHR is based on past races and resolves quickly, often in less than 10 seconds.

Pari-mutuel races are live or upcoming events and typically last several minutes.

Player experience

HHR gameplay is fast-paced and generally solitary, similar to slot machine play.

Pari-mutuel betting is less rapid and often more social, with bettors watching races live alongside other gamblers or spectators.

Legality

HHR operates within legal gray areas in some jurisdictions because of its limited skill-based structure. In several states, it is classified as a form of pari-mutuel betting, making it legal.

Traditional horse racing is clearly defined under federal and state laws as a skill-based form of pari-mutuel wagering.

HHR vs. pari-mutuel betting: what to know

Historical Horse Racing differs from traditional pari-mutuel betting in several meaningful ways. However, the core wagering structure is the same. In fact, HHR is classified as a form of pari-mutuel betting in states such as Kentucky and Wyoming.
