Monkey Parasite

This game is based in a book called "The Selfish Gene" by Richard Dawkings. 
There is an explanation of why some animals tend to live in community, and interact with each other in a collaborative way. 
So here we have what is the best strategy to ged rid of a new plague of parasite.

You can clean yourself, but what about those parasites that you cant not reach like those in your head?. You have to ask to someone else to clean you.

We give you 3 stretegies: Incautious, cheater and rencorous.

The incautious: clean every monkey that he sees.

The cheater: let other monkeys clean him but he doesn't return the favor

The rencorous: he cleans everyone who has cleaned before.
