Offside?!

I tried explaining the offside rule to my kids many times during the 2026 World Cup, and it never quite clicked. I looked for tutorials and videos, but they were all too complicated. So I built this little game instead. It's free, no sign-up needed, and I think it works pretty well.

It covers every situation, even the niche ones (back passes, throw-ins, goal kicks, etc.). It's still in beta, so you might run into a few bugs:  sorry in advance!
