There may be variations and additions to these rules. For example, if players who are sitting down, because they are "out", are able to catch a throw, then they may re-enter the play.
These guidelines may have variations or supplementary regulations. To illustrate, if individuals who are not currently engaged in the game (i.e., those who are "out") can still impact the outcome by catching a thrown object, they could potentially be readmitted into the game.
