Obstacle
Sky Dodge
No gates at all. Free-floating barriers drift up and down, and you have to aim at where they will be.
Cloud Runner
Cloud Runner has no gates. The obstacle is a single continuous corridor that winds up and down the screen for as long as you can stay inside it. Where a gate game gives you discrete decisions, this gives you one long one that never finishes.

How to Play Cloud Runner
- Press Start and flap with Space, W, Arrow Up or a tap.
- The corridor winds continuously — there is no safe moment and no gap to aim at.
- Make many small corrections rather than a few large ones. A hard flap here is usually a mistake.
- Follow the centre line of the corridor rather than hugging whichever wall you can see best.
- Touching either wall ends the run. Distance is recorded in metres.
Objective
Stay inside the corridor for as long as you can. Distance flown is the recorded result; there are no gates to count.
Controls
| Action | Keyboard / mouse | Touch |
|---|---|---|
| Flap | Space, W or Arrow Up | Tap anywhere on the play area |
| Pause / resume | P or Esc | Pause button in the game bar |
| Restart | R | Restart button in the game bar |
Pause with P or Esc, restart with R. The game pauses automatically if you switch tabs. More detail in keyboard controls for browser games and touch controls for arcade games.
About Cloud Runner
The corridor is generated from two sine terms of different periods, which produces a wandering centre line that never repeats obviously and never jumps. Its width narrows gradually as the run goes on and its wander amplitude increases, so the corridor gets both tighter and more aggressive — but always smoothly, because a discontinuity in a continuous wall would be a wall.
What this tests is the thing every other game on the site tests in short bursts: holding a height and changing it deliberately. There is no moment here where you are safe and no moment where you have nothing to do. A gate game lets you coast between obstacles; a corridor does not, and that makes it unusually good practice.
The characteristic failure mode is over-correction. Because the walls are always close, every small error feels urgent, and the instinct is to flap hard. A hard flap in a narrow corridor puts you into the ceiling roughly as often as it saves you from the floor. The players who do well here are the ones who make many small corrections instead of a few large ones.
Distance is the recorded metric rather than score, because there is nothing discrete to count. The corridor's minimum width is capped well above the flyer's diameter plus a correction, so it never becomes a squeeze that only luck can pass.
Flying Mechanics
Cloud Runner uses the site's shared flight model: gravity acts continuously on your vertical velocity, a flap sets that velocity rather than adding to it, and hard caps on rise and fall speed mean no situation is ever unrecoverable. The mechanics this game leans on are Flapping, Gravity, Narrow Gaps and altitude control.
If you want the numbers behind that, how flappy-style games work sets out the whole model, and how flapping mechanics work explains why a flap that sets velocity behaves so differently from one that adds to it.
Cloud Runner Tips & Strategy
- Small, frequent flaps. The corridor punishes big corrections far harder than it punishes small errors.
- Aim at the centre line, not at the wall you can see. Hugging a wall removes half your margin for free.
- Look ahead along the corridor rather than at the flyer — the shape of the next second is always visible.
- When the corridor climbs steeply, add one flap to your rhythm rather than switching to rapid flapping.
- This is the best place on the site to learn altitude control. Twenty minutes here shows up everywhere else.

Cloud Runner — FAQ
Why is there no score in Cloud Runner?
There is nothing discrete to count — the corridor is continuous, so there are no gates to pass. Distance in metres is the honest measurement and is what gets recorded.
Does the corridor ever get too narrow to pass?
No. The minimum width is capped well above the flyer's diameter plus room for a correction at the current fall speed, and the corridor stops narrowing before it reaches that floor.
Why do I crash more when I try harder?
Because urgency produces large flaps, and large flaps in a narrow corridor overshoot. The corridor rewards frequency over force — many small corrections beat a few strong ones.
