A pinball game that allows you to experience the economic term ``double match of desire'' appears

In bartering, the condition in which what you have is exactly what the other person wants and what the other person has is exactly what you want, that is, the supply and demand of the two parties are perfect The probability of encountering a condition that matches is infinitesimally low. In economic terms, this situation is called a ' double coincidence of wants,' and it has evolved into the idea that it is better to rely on alternative means of money rather than relying on extremely low probabilities. ' Dual Coincidence ', which expresses such a double coincidence of desires in a game that is easy to understand, was exhibited at the Bank of Mexico Museum.

Dual Coincidence is likely the world's most complex electromechanical game

You can see how Dual Coincidence works in the video below.

Dual Coincidence is a pinball table with a metallic look.

The difference from normal pinball is that it has a special structure in which five pinball tables are connected in a star shape. Each table has 1 person and 5 people have to play at the same time.

A rotating mechanism called 'carousel' is attached to the central connecting part. There are 6 carousels in all, each with a picture of 5 different fruits. The fruits

represent 'corn', 'carpenter', 'medicine', 'shoes' and 'water', all of which are one 'good'.

Each player can only produce one different kind of good through pinball. When you produce that good, a ball will be sent to the carousel connected to your platform, and the picture of the fruit corresponding to the good will light up. It's OK to light up all five types of goods, but since you can only produce one good, you can't achieve your goal unless you exchange it for goods produced by other players.

Dual Coincidence is an artwork created by art studio Andy Cavatorta Studio for the Bank of Mexico Museum.

According to creator Andy Cavatorta, Dual Coincidence has 17 computers, 6 servo motors, 10 optical sensors, 12 rotary encoders, 35 inductive sensors, 75 switches and 115. Solenoid actuators, 704 lights are built in, and it seems that it has a very complicated structure.

We also put a lot of effort into the sound aspect, and the music is played by 25 metal chimes. This chime is made of metal that is polished from scratch, and the pitch is adjusted with a tuner.

It seems that the production cost of Dual Coincidence is about 300,000 dollars (about 40 million yen). Mr. Cavatorta commented on the exhibition, ``Many museums have interactive exhibits using touch screens, so I thought it would be nice to have a physical and tactile one. I made it because I wanted to have an unpredictable social element.'
