A sample level of the Kary Series 🞶 Game. It would show you numbers of a sequence and then you had to come up with a formula that represented the series. You had two variables x and p. x was the current index, and p was the previous value. Powered by the NCalc system, you could write complex formulas for the game. (1/2)

Kary Series 🞶 game (2/2): If your formula did not work, the game would have rendered the expected vs real for you to see where the problem is arising from.
