Solution X

Solution X is a procedure that differs from the typical way races are recorded. Instead of competitors racing each other live, each competitor records their run within 24 hours of each other, with a host or moderator present to verify it. If a competitor fails to do their recording within 24 hours, they will automatically be declared the loser. This is usually done if competitors are having a hard time being available at the same time and often used when a deadline is approaching for having matches done.

History
Solution X was initially realized during International Spyro Grand Prix 2 by hosts CrystalFissure and Nintendogen64. The initial way it was done was the hosts provided the game & goal in private and are given 30 minutes upon receiving it to plan and record their run. The way the game & goal was decided became less strict over time, with competitors deciding it themselves and recording it at their leisure. Competitors still are required to record it within 24 hours.

Solution X has been adopted in multiple tournaments since ISGP 2, such as Super Gex League.
