It's inevitable, sometimes a competition will end with two or more of the top players on exactly the same score.
In these situations, the player that got to the highest score first will be the winner.
For instance, say a "Weekly Deals Won" competition ends with Alice and Bob each on 20 deals. Alice closed her 20th deal on Friday at 4pm, and Bob closed his 20th deal on Friday at 4:30pm. Alice would be the winner in this situation.
