A man who, for the past 17 years, has struggled to finish a children's educational game called 'The Ambulance Gridlock Game', has finally decided to 'call it a day', and admit defeat.
The game, played on a plastic 6x6 grid, where 'vehicles' can be moved up and down, and from side to side, in order to free the space for a trapped ambulance to escape the gridlock, was purchased by Moys Kenwood in Bangkok, Thailand in 2002.
Since then, he has devoted thousands of hours to the seemingly-impossible task of freeing the white plastic ambulance, with its little red cross, from its prison in the gridlocked traffic.
"There's a little booklet that shows you how to set up 50 puzzles, and another that provides the solutions. Unfortunately, these solutions are all in Thai - not that I would've cheated anyway, you understand."
A friend of Kenwood's who asked to remain anonymous, said:
"It looks, to me, like he may have set the game up wrongly in 2002."
