One tap flips gravity.
A gravity flip runner you can play right here: no download, no sign-up. Tap, click or press space to jump between the floor and the ceiling. Miss the spikes and walls.
Ready?

Space, Enter, click or tap flips gravity. Press P to pause.
How to play
- Tap once to flip. The runner leaves the floor and lands on the ceiling, or the other way round. It takes about a quarter of a second to cross.
- Read the side, not the shape. Every hazard is attached to the floor or the ceiling. You only need to be on the other one when you reach it.
- Tap again in mid-air to turn back. When two hazards sit close together on opposite sides, flip, then flip straight back before you land.
- Each one you pass is a point. Every 8 points the tunnel changes colour and speeds up.
Four habits that raise your score
- Flip early. A flip that starts late clips tall walls on the way across. If you can see which side the next hazard is on, go now.
- Look one hazard ahead. The one in front of you is already decided. Your eyes should be on the one after it.
- Stay put when you can. Two hazards in a row on the same side need no tap at all. Extra flips are how most runs end.
- Use the rhythm. After each speed-up the gaps arrive on a faster beat. Give yourself two or three hazards to find it before you push.

Questions
How do you play a gravity flip runner?
Your runner moves forward on its own. One tap, click or press of the space bar flips gravity, so the runner crosses from the floor to the ceiling or back. Hazards sit on one side or the other. Be on the opposite side when you reach them.
Can I flip again while I am in the air?
Yes. A second tap in mid-air reverses the flip and sends the runner back to the side it came from. It is the way through two hazards that sit close together on opposite sides.
Is this the same as the Fluxo iPhone game?
No. This page is a small browser demo of the core idea. Fluxo: Gravity Runner on iPhone is the full game, and scores from this page do not carry over to it.
Does it work offline or save my score?
Once the page has loaded it needs no connection to keep playing. Your best score is kept in this browser only, when the browser allows it, and is never sent anywhere.
