Party Match making

In this game every guest is given 10 cocktail sticks.

As guests mix and walk about they take a number of sticks in one hand and, with their hand closed, ask a 2nd person “odds or even?”
If they get the right answer, they give a stick to the 2nd person.
Now they swap and person 2 asks person 1 “Ods or even?”

This continues for a set time until the end is called and the player with the most sticks is the winner.
