Video Summary

To solve this problem, we first find that the rugby team's average score for the 7th, 8th, and 9th games was 22 points. For the first 6 games to have a lower average, they must have scored at most 131 points. For the average after 10 games to be more than 22 points, their total score must exceed 220 points. Therefore, their minimum requirement for the 10th game is calculated as 221 total points minus the 197 points already scored in the first 9 games, leading to a minimum of 24 points. Thus, the smallest number of points in the 10th game is 24.
