Executioner's game (7)

I believe the answer is:

hangman

I believe this is a double definition.

'executioner's' is the first definition.
(hangman is a kind of executioner)

'game' is the second definition.
(game played on paper)

(Other definitions for hangman that I've seen before include "Word game - executioner" , "Official executioner" , "Public executioner like Jack Ketch" , "Word-guessing game - executioner" , "He suspends" .)

I've seen this clue in The Everyman puzzle in The Observer.
