It's hard to point out the mistake without seeing the actual task and your code. Could you paste both here? That makes it much easier to explain why it isn't working instead of just giving the answer. In general, I recommend reading the requirements line by line and checking that your solution satisfies each one. Many beginner with clicker games and CodeGym tasks fail because of small details like using the wrong variable name, incorrect output format, or forgetting a required function call.
