The Reserve Amount qualifies that someone can only win/place in a competition if they have achieved a minimum qualification (the Reserve Amount) for that specific prize. This feature is optional!
For example- Let's say I came in first place with 79 points. There is a first place prize with a reserve amount of 100. So even though I came in first place, I am not eligible to receive the prize because I did not satisfy the reserve amount.
