Most of us will have played Monopoly at least once in our lives although I doubt many of us have lost any sleep wondering about the location of 'GO'.
But the mystery must have caused someone a little insomnia - enough for them to decide to solve the 75-year-old riddle. Mapping experts at Ordnance Survey used digital mapping to trace and plot all the square on the board game on to a map of London.
They discovered that the iconic game's start square is Lambeth North tube station on the Bakerloo Line, near the London Eye. Under the rules of the game a player collects £200 from the bank every time they pass 'GO'.
So there you have it. Dust down your battered Monopoly board (if you can find it), set everyone round the table for a game, then when the opportunity arises, you can impress your company with your newly acquired knowledge. Not a bad way to spend an August Bank Holiday Sunday evening.
