Hi John!

No this challenge doesn't need to be updated. I also had that problem when I were there and I thought the same thing as you, but I found out that I am overcomplicating it. The problem in your code is that you actually don't need the totalScore, because the initialScore will be 9 after the second line and if you use that initialScore instead of the totalScore, your code will work. And just to know, you cannot use the += operator like you used in the third line of code, because it isn't correct syntactically.

Your code should look like this:

var initialScore = 8
initialScore += 1
let isWinner = initialScore != 10
