You can peruse the official USTSA Foosball Rules of Play here:
Here are a few notes and "house rules" specific to the Olympiad:
- Each "Nation" will submit one team (two players) to the foosball tournament.
- The first team to 10 goals wins the match.
- Dead balls are re-served (not touched or moved).
- NO SPINNING THE RODS (Spinning is defined as the rotation of any soccer
figure more than 360 degrees before or after striking the ball. In calculating
the 360 degrees, you do not add the degrees spun prior to striking the ball to
the degrees spun after striking the ball.)
