Decamentathlon
The Decamentathlon is a multi disciplined games event that was created as part of the first Mind Sports Olympiad. It was founded to try to find the best games all-rounder in the world and hence possibly the best games player. It was given a prize fund of £10,000 for the inaugural competition, that equalled that of the highest funded event at the first MSO sponsored by Skandia. However, the other events were spread over multiple playing sessions whereas the Decamentathlon was held over just a single session. This event was initially hailed as the MSO flagship event. Although, the Mind Sports Olympiad's other new event the Pentamind has since become regarded as the more significant event despite not having a fixed format.
