An anything goes match for any sport, fight, or competition

Motel matches used to be matchbooks with the motel's name on the cover.

Elvis Costello had a song on his "Get Happy!!" album in the 1980's with that same title "Motel Matches".

Falling out of your open pocketbook
Giving you away like motel matches"

The final, and deciding game between two tied teams/opponents.
