You need to use , between numbers, I don't think a lot of people understand this. So maybe a little ? Icon that people can click to read how it works. Besides that it works perfectly, I like doing these riddles but if you get them wrong they don't always explain why. This app helps you figure out what they wanted.

Maybe it can be improvable, but it is an awesome idea. It can help in dramatic ways many activities. Thank you
