This is a clone of The Great RGB Guessing Challenge. The challenge works like this: You are presented three numbers ranging from 𝟢 to 𝟤𝟧𝟧 representing a rgb color and three color bubbles. To get a point you must choose the color bubble corresponding to the rgb values. The more points you get, the higher your score.
- Click on the bubble to choose it.

To get a number’s palindrome in a programming language like python is easy. There are ways to swap between integer and string and strings can be manipulated.
>>> n = 1234
But I wanted to create a mathematical function 𝑝(𝑛), which returns an integer’s palindrome. Thus 𝑝(𝟣𝟤𝟥𝟦) = 𝟦𝟥𝟤𝟣.
Firstly, I needed a way of determining the number’s size. In base 𝟣𝟢 the length is calculated using the logarithm to said base.
Secondly, I need a way to isolate a specific digit. Using the floor function, this function returns the 𝑖-th digit (starting on the right with 𝑖 = 𝟢).
Thirdly, both of these functions can be used to split up the number into a sum.
Fourthly, I only need to swap the power of ten at the end to get my palindrome function.
Thus the final function 𝑝(𝑛) is defined.
To check if the formula is correct, I use 𝟣𝟤𝟥𝟦 (as seen above).

This game is a recreation of the famous game Simon. In the game there are four colors which form a sequence that is expanding every cycle. The aim of the game is to memorize said sequence as far as possible.For more information on the Simon game visit this Wikipedia entry.
