More or Less, BBC Radio 4's program that takes you on a journey through the often abused but ever ubiquitous world of numbers, has recently returned to the airways, and next Monday (17th December 4.30 pm), regular Plus contributors Rob Eastaway and John Haigh are featuring on the program discussing the maths of Monopoly.

Eastaway and Haigh have written for Plus many times on a range of topics including:

• Coincindences;
• The national lottery;
• The maths of cricket and football;
• Remembrance of numbers past;
• Maths and Magic.

Plus spoke to Eastaway about the science of Monopoly, and without giving too much away, Eastaway commented that because the "Go to jail" square is the most frequently visited sqaure on the board, the orange properties are the best investments, as players leaving jail are most likely to then land on these properties.

This means you should invest in Bow Street, Marlborough and Vine Street — or in the US version, St James Place, New York Avenue or Tennessee Avenue.
