Run 1 — Play Free Online

Run 1 is where the whole series starts: a small grey alien sprinting down a tunnel floating in space, with nothing under the path but gaps and the void. It is a simpler game than the sequels, and that is the appeal. There is one idea, and you learn it in about thirty seconds.

The idea is that the tunnel is round, and you are not stuck to the floor. Run onto a side wall and the view rotates so that wall becomes the new floor. Every hole in the path can be avoided by turning the tunnel, jumping across, or both. If you came to this site for Run 3, this is the version to play to see where the gravity-flipping started, with fewer systems and a plainer, quicker rhythm.

A run is short. You move forward automatically, react to what appears, and any slip into open space sends you back to try again. That makes it a good fit for a few minutes between other things, and a good way to warm up before the harder entries in the series.

How to play

Use Left and Right, or A and D, to steer. Space or the Up arrow jumps. To change surface, steer onto a side wall of the tunnel. The tunnel then rotates so that wall becomes the floor, and the gaps that were on the old floor are now overhead and out of your way.

Most of the game is reading the path a little ahead of you. Look for where the solid tiles continue, which is often on a different wall from the one you are on, and move to that wall before you reach the gap instead of jumping at the last moment.

Tips

• Do not jump by reflex. Often the safer option is to walk onto the wall and let the tunnel turn.
• Make small, deliberate taps on the steering keys. Holding a direction for too long drives you off the edge of a tile.
• Keep your eyes on the far end of the tunnel and not on the alien; the gap you need to react to is the one that is still coming.
• After a fall, note where it happened. The layout does not change between attempts, so a second try is easier than the first.

Similar games on Run 3

Run 2 keeps the same rotating-tunnel idea but adds more to think about, while Run 3 is the headline game on this site and the most developed of the trio. If you like the tunnel view but want raw speed rather than platforming, Tunnel Rush and Slope are fast reflex runners where you dodge obstacles and never stop moving.

It suits anyone who likes short, replayable challenges. A keyboard makes it easiest, since you need both steering and jumping, and it runs in the browser with nothing to install.
