Using "who achieved the score first" as a tiebreaker creates an unfair advantage that has nothing to do with player performance.
Players begin playing at different times depending on their time zones and convenience. So earlier participants naturally have a higher chance of securing top ranks in case of a tie, in the current system.
Such a tiebreaker is not a reflection of skills but just "who got to play earlier"
A fairer system is to assign the same rank to players with the same score. For example, if two players tie for 3rd place, both should be ranked 3rd, and the next rank should be 5th.
This ensures that rankings are based solely on performance and not influenced by timing.
