Crossy Chicken is an endless hopper: your chicken crosses lane after lane of traffic, logs and hazards, and every hop has to be timed into a gap that's actually going to be there when you land.
It's the format Frogger invented and Crossy Road made endless. Runs are short, the restart is instant, and the score is simply how far you got.
No — it's endless. The hazards get denser and faster the further you go, and your score is the distance hopped.
Hop onto floating logs or platforms and keep hopping — they drift, so standing still carries you off the screen.
Yes — tap to hop. Nothing to install.
