There's a few things going on here. First, you have two variables initalScore = 8 and initialScore = 8. Note the spelling. Because one is misspelled they're now two separate variables. Secondly, it asks you to increment totalScore by one, but you're incrementing it by two. Third, you're setting isWinner to the integer 10. What it wants is for isWinner to hold a boolean value (a true or false). Is the person a winner or not? To do this we have to evaluate if the totalScore is equal to 10. If it is, then they're not a winner. If it's not equal to 10 then they are a winner. Take a look at how to do this here:

// Enter your code below

var initialScore = 8
let totalScore = ++initialScore

let isWinner = totalScore != 10
