In the Arena two players enter the same game with the same time limit, the same scoring table and the same starting conditions. The player with the higher score wins the prize. There is no random element in the result.
Each match shows the entry amount, the prize and the applicable game rules version before a player commits. Where scores cannot be separated by the published tie-break measures, the entry is returned to both players.
Paid entry is restricted by age and by location. Competition eligibility, excluded territories and fair play obligations are set out in the published rules.
