Your tiebreaker page (i.e., https://help.yahoo.com/kb/SLN6629.html) lists nine rules for breaking ties for Weekly Pick'em contests. Rules 1-3 refer to "the first Tiebreak Game" while Rules 4-6 refer to "the second Tiebreak Game." While it is clear that there are exactly two tiebreaker games and which two games are the tiebreaker games, it is not clear what is meant by the "first" of these two games. It could mean any of the following (and perhaps even something else).

1. The first of the two tiebreaker games to be started.
2. The first of the two tiebreaker games to be finished.
3. The one of the two tiebreaker games that appears higher than the other in the list of all of the games being contested.
4. The one of the two tiebreaker games that appears higher than the other in the list of the two tiebreaker games.

I suspect that your intended meaning is given by the last of these four options. If so, then you could clarify this ambiguity by clearly labeling the two tiebreaker games as "First Tiebreaker Game" and "Second Tiebreaker Game," or something similar.
