I can't figure out why this solution is incorrect for part 2. let lose = totalScore == 10 let isWinner = !lose

I keep coming back to this challenge but I can't figure out what is wrong with this solution.

var initialScore = 8 let totalScore = ++initialScore let lose = totalScore == 10 let isWinner = !lose

Your code technically works, but treehouse challenges are often pretty picky about the solution. Even if the result is right, if the method is not what the challenge expected it will sometimes fail you.

The problem is that task 2 can be solved without creating any variables other than isWinner, you don't actually need to create the lose variable, and doing so is confusing the challenge checking code since it it not expecting it.

The answer it expects looks like this:

var initialScore = 8
let totalScore = ++initialScore
let isWinner = !(initialScore == 10)
