Frequently Asked Questions about Run 3

How do you play Run 3?
Use the left and right arrow keys (or A/D) to move across the tunnel. Press Space or the Up arrow to jump over gaps. The tunnel rotates when you reach the edge, keep running as long as you can!
What happens when you fall off the edge of the tunnel?
Running off the left or right edge rotates the entire tunnel 90 degrees so the wall becomes your new floor, the gravity flip mechanic. If you fall through a gap in the tiles, you lose a life. Lose all 3 lives and it's game over.
Does the game get harder over time?
Yes. The tunnel speeds up gradually and more tiles become missing as your distance increases. Early on there are almost no gaps; by 100+ meters the gaps become much more frequent and the speed challenge is real.
Can I play Run 3 on mobile?
Yes! Tap the left/right arrows below the game to move, and tap JUMP to leap over gaps. The game works on any mobile browser with no download required.
How many lives do I get in Run 3?
You start with 3 lives (shown as green dots at the top). Each time you fall through a gap you lose one life. A short invincibility window activates so you have time to recover. Lose all 3 and the run ends.

About Run 3

Run 3 is the iconic infinite tunnel runner set in deep space. You control a small alien sprinting through a cylindrical tunnel that stretches endlessly forward. The tunnel is built from hexagonal tiles, and some of those tiles are missing, leaving gaping holes into the void. Your job is simple: don't fall in. Move left and right to dodge gaps, jump over smaller holes, and when you reach the edge of the tunnel, keep going, the world rotates 90 degrees and you're suddenly running on the wall. The original Run 3 was a beloved Flash game from the early 2010s; this version brings the same tunnel-running magic to modern browsers with no plugins or downloads needed.

How to Play

  1. Press ← → arrow keys or A/D to move left and right across the tunnel.
  2. Press Space or ↑ to jump over gaps.
  3. Run off the left or right edge to trigger a gravity flip, the wall becomes your new floor.
  4. You have 3 lives. Each fall costs one life. Invincibility flashes briefly after each hit.
  5. Survive as far as possible, the tunnel speeds up and gaps multiply as distance increases.
