Courage or Truth or COURAGE ONLY?
Add the players' names to the app, and the app will automatically generate tests for each player.
Any player who does not agree with the Test gets a vote (not only the one doing the test gets a vote, but also the one who is being tested).
At 2 votes you are out of the game.
Now players who are related can play without having inappropriate questions, just select related when adding the name.
