Board Game Arena

I have some set for some games, but there are other games I want to set a bell reminder for, but do not see a way to do it.

Do all games not allow a bell reminder?

That is correct. Only some games have these bells. I believe they are setup for less poplar games.

Who decides whether a game is worthy of a bell?

I am interested in a new Beta game, Formula D that I assume is a low interest game.

Sometimes you have to click on play in the new lobby format to be able to scroll down and see the bell you wish to use.
