Tetherline

How to play Tetherline

Tetherline is an aiming and timing game. A probe leaves the station at the centre and must meet the glowing delivery window on the orbit. The window moves on some routes, so choosing when to launch matters as much as choosing where to aim. The rule stays consistent: line up with the target and send the probe before it passes.

• Arrow keys or A/D: rotate the aim line in small steps.
• Space or Enter: launch the probe along the marked direction.
• Tap the Canvas: aim and launch directly on a touch screen.
• P or Escape: pause the current route without losing the attempt.

Three sectors, fifteen routes

Each sector contains five deliveries. The early orbits leave a wider window so you can read the visual language; later routes move faster, narrow the opening, and introduce blockers. Difficulty comes from visible motion, direction, and timing, never from a hidden control.

Charge, recovery, and local rhythm

You begin with three charge points. Sending a probe outside the window or into a blocker spends one point and restarts that route. When charge runs out, one recovery restores two points; it never creates deliveries, progress, or a best result. After the first interaction, the browser creates short rhythmic pulses locally. There is no audio track, download, or asset from another domain.
