The abilities mimic the game of hangman. You tell each player how long the secret word is. You may even draw out blanks as one does in the game of hangman.

You must choose a word in a language each player understands. If there are multiple such languages, you should specify which one you’re using as you secretly note the word.

If a guessed letter appears multiple times in the word, you should fill in each instance of the letter in the word.

Each letter can be guessed only once.

If Hangman changes controllers, the person who originally chose the word continues to fulfill their duties as letters or words are guessed. Now that this player doesn’t control Hangman, they will have a much easier time figuring out the word.

Hangman : règles, fonctionnement et interactions (MTG)

Hangman is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

As this creature enters, secretly note a word with six to eight letters. : Target player who doesn't control this creature guesses the noted word or an unguessed letter in that word. If they guess wrong, put a +1/+1 counter on this creature. Any player may activate this ability. When a player guesses the noted word or all of its letters, sacrifice this creature.
