# Play to win!

In workshop, we were looking at the mathematics behind puzzles and board games. One of the games we looked at was Sudoku. People argue that there is no arithmetic in Sudoku as there’s no adding or calculations necessary. However, surely being able to look at patterns and sequences across the Sudoku square is using basic mathematical principles since maths is about seeing patterns in nature (Sawyer, 1955, cited in Boaler (2010, p.17). Furthermore, it does involve problem solving. Alternatively, it could be viewed that it Is just a process of elimination since you could use shapes, animals or letters instead of numbers but this would still involve analysing patterns.

The board game that I chose to look at for the workshop was Monopoly as there have been many summers when my friends and I have spent hours trying to win at Monopoly and now I’ve discovered that maths can help me win!

When I played monopoly, the only I thought I gave to the mathematics behind it was to buy Park lane, Mayfair and the train stations as once I purchased these, I could build houses. Then when someone landed on my property, I would get a considerate amount of money from people owing me rent (although I wasn’t fully aware that this was going back to basic mathematical principles (Ma, 2010, p. 104). The thrill of this was one of the most exciting parts of the game! I was looking at buying properties that were worth the most instead of looking into the chance and getting the properties which are the most landed on (standupmaths, 2016)

The basic mathematical concepts that link with Monopoly are chance and probability. This is because when you throw the dice it is up to chance what the outcome is. If you want to learn more about chance and probability visit a previous blog post of mine (Noble, 2017). Other basic concepts used in the game are adding and subtracting as the cashier when calculating rent as well as counting number of squares as you move your object (in my case that was always the dog).

A woman girl from Northern Ireland was crowned the UK champion for Monopoly and she gave some tips as to how you can win at Monopoly which relate to fundamental mathematical concepts (Telegraph, 2015). The basic mathematics of probability explains that Park Lane is actually the least landed on property therefore, I shouldn’t purchase it!

However, I was on the right path to success by buying up all the Railway stations because “…they deliver a more constant level of avenue over the course of the game.” (ShortList, no date). In addition to the stations, it is also best to buy the red properties and the orange ones as these are the top two most landed on properties on the board. They also do not cost much but bring in more money once you put hotels on them (ShortList, no date). However, is it beneficial to always place a hotel on your properties?

In the past, always would have bought four houses and then moved to buying hotels for properties. However, the UK champion of Monopoly says that “Once you’ve reached 3 houses, the amount that the rent increases with each house maxes out.” (Telegraph, 2015). Therefore, fundamental mathematics was used to help figure out the best way to win!

Furthermore, jail is the most commonly landed on place on the board, this is probably because there are several ways in which you can go to jail: landing on go to jail; community chest or chance (standupmaths, 2016). Thus, when you are in jail you should try and stay there for the longest time possible later on in the game (ShortList, no date). This is because other people will have bought up properties, put up houses or hotels. Therefore, the longer you stay in the jail the zero probability or chance you will have of landing on their properties and losing money since you are not moving.

Another interesting point to note is that according to probability, the most rolled number in Monopoly is 7. So, if you are going to place houses on your property you should wait until they are 7 spaces away from your property so that you can win more money (Robitzski, 2017).

However, you might think using maths to win ruins the fun but these are still interesting observations. I know in the future when I play monopoly, I am going to apply my mathematical knowledge of chance and probability and what I have learnt from this blog to try and win. For example, I am going to try to purchase the red and orange properties and stay clear of buying park lane!
