What is Scavats?
1.
Scavats was used in a Scrabble game on a triple word square. Although not a real word, (at the time) it went unchallenged and the player came from many points behind to win the game. (By getting 50 points for using all 7 tiltes and the triple word score.)
Now when a false word goes unchallenged, a scavats has been played.
