The point of the game is not to one up each other. It's not to 'win' as that kinda ruins the whole spirit of the games section... the point is to be creative and to let others be creative too.
It's happened before that someone posted something that they thought 'won' the game because it was just so hard to find a word that didn't contain any of those letters.
In every case, people who want to just play have just moved past them and kept on playing the game.
Ofc it isn't, but it's still fun being forced to think outside of the box
