Alexa -- P3RS1ST Number Game (Persist)

Inspiration

Mathematical persistence (umm, yeah)

What it does

Plays an interactive number game with you

How I built it

Node.js, Lambda

Challenges I ran into

Defining the rules clearly and implementing them, general debugging

Accomplishments that I'm proud of

Creating a unique interactive game that can be played both by voice on Alexa and in written form (puzzle book)

What I learned

There's more to life than Sudoku ;)

Alexa -- P3RS1ST Number Game (Persist) skill description

Match wits with Alexa in this nifty game of numbers. The object of P3RS1ST ("persist") is to reduce the starting number down to the target single-digit number by taking turns naming interim numbers, formed using all the digits of the current number in only 1 of 3 allowable ways: the sum of the digits (add them all together), the product of the digits (multiply them all together), or the same digits with a single digit appended (append a digit 0-9). Whoever reaches the target number first wins. As an added challenge, try to use as few turns as possible.

Example interaction: Alexa: Ok our starting number is 12345 and our target number is 5 [you selected a 5-digit game] You: 15 [sum of the digits] Alexa: 159 [same digits with a ‘9’ appended] You: 14 [product of the digits] Alexa: 5 [sum of the digits --- matches target number, Alexa wins]
