During Passover, Jewish kids hunt for the affecomen, a piece of matzah wrapped up in a napkin. Uncle N would give every child $1.00 I noticed that his 2 kids always found the prize. He clearly saw where the matzah was hidden, and gave his kids the clues. I complained to my parents to no avail, then just got passive. No point in really looking, if you are always going to lose.
We try to be fairer.
