Cross the Road Safely
Only go when the gap is really clear.

What is this experiment about?
Cars keep rolling past the crossing. Watch the gaps carefully and tap Cross only when you're sure it's clear — three close calls and the round ends.
Questions kids ask
- How do I know when it's safe to cross?
- Wait until no car is close to the crossing and you have enough time to walk all the way across before the next one arrives.
- What if a car is far away?
- A car that looks far away can arrive faster than you think — always leave yourself extra time.
- Why does the game get faster?
- As you cross safely more times, traffic picks up — just like a real street gets busier, it keeps testing your timing.
