Sorting through the loft, I came across parts to some old Monopoly games. This games seems to have been around forever, and I have had several versions – and fragments of other versions – in store for many years.
These instructions for a short game from 1961 struck me as well worth remembering next time the game comes out for another round.
Side 1 Monopoly “Rules for a Short Game”

Side 2 Monopoly “Rules for a Short Game”

I especially like this version:
TIME LIMIT GAME: Agree before starting upon a definite hour of termination, richest player at that point is the winner. Before starting game Title Deed cards are shuffled and cut, and Banker deals Two Title Deeds to each player. Players immediately pay Bank price of property thus dealt to them.
