If any form of chance is involved, fantasy sports will be subject to gambling laws and thus may be deemed illegal. However, a gray area exists whether fantasy sports competitions involve chance (or luck) rather than pure team selection skills. As betting in professional sports is strictly regulated worldwide, fantasy sports offer a form of proxy sports bet. The performance of their fantasy teams is dependent on the actual on the field performance of these real-life players. Fantasy sports competitions allow sports fans to become their own managers, to select and organize fantasy teams from existing real-life players in professional sports leagues.
