5 Rex is a dinosaur endless runner in the lineage of the Chrome dino game: your dinosaur runs forward automatically, obstacles arrive faster the longer you last, and one collision ends the run.

No — it's a similar dinosaur runner with its own art and obstacles. The genuine Chrome T-Rex runner is on our /dinosaur-game page and works offline.
Yes — tap to jump. Nothing to install.
Use short taps rather than long holds, and watch the right-hand edge of the screen so you see obstacles early enough to react at high speed.
