How do you play Clue?

There are character cards, room cards, and weapon cards. One of each goes in an envelope, and nobody sees them.
Dice are rolled, and you go around the board, which is a blueprint, sorta, of a house.
Along the way you collect clues.
When a player thinks they know the killer, weapon, and room, they make a guess. If they look at the cards, and are wrong, they are out. You don’t want to make your guess too soon, you could be wrong, but if you wait too long another player could beat you to it.
I have an Xbox games which includes Clue.
The more players involved, the more challenging it is.
