Player 1 starts the game every time and alternates with player 2.

Hello, how do i know when is the turn of player 1 or 2?

i have the same error, i don't know what to do

if.index doesn't find spcace in your alphabet list, it's not an error?

Try running your solution with following test case:

assert.strictEqual(add(111, 1), 112);

Not a kata issue.

Not a kata issue, print the numbers, check why your code fails (hint: nobody told you the two numbers have the same amount of digits).

it looks like the "random" tests change around each time you click attempt?

That's the very definition of random ;)

thank you man

Don't print, but return the result.
