Game involving prime numbers.
Now that we can represent all integers in three-dimensions, it is very easy to invent new mathematical games. One possibility is to try to guess all the physical components of a given prime number. For example, the first and only even prime is 2. It consists of a single column of three green cubes. Yet, do not forget that an empty space also exists. Consider another example like 5. Such prime is composed of a single orange cube followed by an empty space and a column of three green cubes. This idea provides the starting point for many practical applications.
