Perhaps the best known virtual horse race is the Virtual Grand National, which was first introduced in 2017, but took centre stage in 2020 after the real-life Grand National was called off due to the coronavirus. Like all virtual horse races, the Virtual Grand National is a computer simulation; computer-generated imagery (CGI) is employed to create a faithful rendition of racecourse, runners and riders and the result is determined by a sophisticated, step-by-step list of rules, technically known as an algorithm.
As in a real-world race, the odds offered on each horse are inversely proportional to its theoretical chance of winning, but the outcome is determined by a regulated random number generator (RNG). As the name suggests, a RNG is designed to generate a sequence of numbers without any discernible pattern but, in a virtual horse race, the favourite has a higher ‘weighting’ in the RNG – and, therefore, more chance of winning – than the second favourite and so on throughout the field.
The Virtual Grand National may be the best known virtual horse race, but virtual horse racing is everyday occurrence with bookmakers, on the High Street and online, in Britain. In fact, virtual horse races, Flat or Jumps, typically take place every few minutes, with win, each-way, forecast and tricast betting available.
