Hi there, rtc ctr!

It looks like you're doing really well so far. The problem here is the (9). That tells Java to get a random number between 0 and 9 where 9 is exclusive. It goes up to 9 but does not include 9. What you're looking for here is (10). That will go from 0 to 10 but not include 10.

Hope this helps! :sparkles:
