Game of Scotland Yard

The end of the game

• If any detective moves onto a numbered location that Mr. X occupies, Mr. X is captured and the game is over. Mr. X has lost the game and the Scotland Yard detective team is the winner.
• If none of the detectives can move because they have run out of fare tickets, then Mr. X wins the game and the detectives lose the game! This can only happen after every detective makes its 22nd move and Mr. X is still not caught.
• If none of the detectives can move because they run out of a particular kind of a ticket, then Mr. X wins the game and the detectives lose the game. This is a remote situation but it is possible that all the detectives could be left with only bus or underground tickets and be stranded on locations that do not use such tickets!
