There's no pause button in the dino game — but you can still pause a run. The trick is that browsers freeze the game for you.
The tab-switch pause
Browser games draw each frame with an animation timer that browsers stop when a tab is hidden. So the moment you switch to another tab (Ctrl+Tab) or another window (Alt+Tab), the dino freezes mid-stride. Come back, press nothing, and the run continues where it left off.
On mobile
Switching apps or returning to the home screen does the same thing — the run is frozen until you reopen the browser. Avoid leaving it too long: an aggressive battery saver can discard the tab entirely, which ends the run.
How our games handle it
We build the games on this site with a fixed-step clock, so a pause can't hurt you: when you return, the game resumes at normal speed with no sudden catch-up jump. Test it on the dino runner or Flappy Dino — jump, switch tabs, come back.
