In many online sportsbooks you will also see a tab for Virtual Sports in addition to sports betting. Those are literal virtual sports. Just like the real sports and real league, some online sportsbooks also have complete virtual competitions.
What you see and experience is comparable to real sports betting. You bet according to the same principle as the real sport or league, for example, on a win for the home team, the away team or a draw. In addition, different odds apply to each match, just like in the real sports world.
However, the leagues and clubs are fake and completely virtual. You actually see a match with goals. Only the images come from the computer and the result is randomly determined by a Random Number Generator (RNG), so completely arbitrary. The whole sports experience and betting options are comparable to real sports betting. However, the matches are fictional, not real.
For many people, the appeal is that the atmosphere of sports betting is simulated, including simulated match images. You can also use Virtual Sports to practice a bit for real sports betting, also because you can usually play with smaller amounts. The playing speed is also high you can bet almost constantly on a new match and see quick results. However, that speed is also a risk factor for vulnerable players, because it is tempting to play another game. Be aware of that risk.
If you are more interested in Virtual Sports, it is good to learn more about the bets and the odds. The results are determined by the computer with an RNG, but at the same time there are predetermined odds.
In addition to Virtual Sports bets, you can also bet on e-sports in online sportsbook. However, that is something else. E-sports are the increasingly popular competitions in which top gamers play computer games against each other.
