In events like basketball or circle of mines, where players get called one by one in succession, or the location of the host is sensitive, like musical chairs, the host should disable the players' vision by darkening it using a command. In basketball and circle of mines, this means that players cant copy the strategy the ones before them used to pass the circle, making it a more fair event depending on your number on the tab list. In musical chairs, this would prevent players from seeing where the host is placing some of the mines.

True or false can also benefit from this, by not having players copy eachother by going to a certain side. This would however require them to continue looking straight so left is always true and right is always false, which they would have to do if they dont want to get stuck on the wrong side from what they expected, or in the middle after the countdown is over.
