Flap when the small lamp at the top swells with the musical beat, and swap the lead with X or Shift before the front goose is exhausted. Gather the flock first, then use wind rivers and golden rising-air columns to conserve strength on the flight toward the sea at dawn. The challenge is how many of the seven geese make it home.
Where to play and the exact controls
Play SKEIN in your browser by CSAF — Core Systems Asset Factory. It launched on October 24, 2026 at 10:05 UTC; the documented build is version 1.0.0. A flight lasts roughly three minutes, with keyboard, mouse, touch and gamepad support.
- Flap: Space, Z, Enter, left click, tap or gamepad A. The lamp at the top swells on the beat.
- Climb or dive: Up/Down arrows or W/S; move the mouse above or below the lead bird, drag, or use the left stick.
- Pass the lead: X, Shift, right click, the touch-screen LEAD button or gamepad B.
- Other keys: Esc/P pauses, M mutes, F toggles fullscreen, and C opens credits on the title screen.
From the opening to dawn
- Find your flock. You begin alone at dusk. Follow the other geese's calls through the clouds and collect them one by one. Once the seven are together, the main flyway begins.
- Learn the beat. Watch the lamp rather than tapping randomly. A flap on the pulse provides more lift at a lower effort cost. The developer built the wingbeat around the music's approximately 60-beat-per-minute pulse.
- Rotate the leader. The front goose works hardest. Birds behind recover while they stay in formation. Swap the leader before exhaustion, preferably on the beat: an off-beat handover temporarily breaks the line.
- Read the air. Wind rivers let the lead bird fly without spending energy. Golden rising-air columns lift and rest the whole flock. Headwinds drain the leader quickly; rain and clouds wear down every goose.
- Reach the morning sea. After the gathering phase, the route includes wind streams, headwind fronts and a coastal storm before dawn. An exhausted goose drops out to rest; the remaining flock continues. Check how many return.
Quick decision table
| Situation | Action | Result and evidence |
|---|---|---|
| Flaps feel inefficient | Press Space on the lamp's pulse | Stronger lift, less effort; developer rules |
| Leader is tiring | Press X or Shift before exhaustion | Shares the burden while followers recover; developer rules |
| Formation breaks on a swap | Time the next swap with the pulse | Off-beat swaps briefly break formation; developer rules |
| A wind river appears | Use that stream where practical | Front bird flies for free; developer rules |
| Golden rising air appears | Adjust altitude to enter it | All birds gain lift and rest; developer rules |
| Headwind, rain or cloud | Avoid lingering and rotate the lead | Sensible tactic based on published fatigue effects; precise route untested |
| Trying for seven survivors | Prioritize beat timing, leader rotation and rest | Recommended approach, not a verified guaranteed seven-goose clear |
FAQ and verification limits
Does gathering seven finish the game? No. It opens the longer flyway toward dawn. Can I just keep flapping? You also need altitude control and lead changes. Is there a fixed number of losses that causes game over? The developer describes a return count, not a confirmed loss threshold. No complete hands-on run, exact hazard positions or optimal swap interval was independently verified for this guide.
Bottom line
Flap on the beat, hand over the lead before exhaustion, use restorative air, and protect the line until dawn. The goose at the front should not have to do the entire night shift.
