A crate rolls off a conveyor into a chasm. Tap to fire a tether at the nearest anchor and swing. Tap again to let go. Land the crate flat on the green pad to deliver it. Sixty levels across four sectors, plus a daily run that is the same layout for everyone.
The crate leaves the belt on its own. Tap anywhere on the play field to grapple the glowing anchor, and tap again to release. The load bar at the top shows how hard the tether is working: cyan is fine, yellow is strain, red snaps. Come down gently on the green pad.
One for delivering the crate. Two for using two grapples or fewer. Three for doing that without the tether ever snapping. Using the swing guide caps a run at two stars.
Tap Guide during a run and, while you are tethered, dots show where a release right now would send the crate. Free players get three guided runs a day; the Full Version has it on every run.
One layout, the same for everyone, one attempt a day. Deliver it to keep your streak. It resets at midnight, local time.
A one-time $2.99 purchase (no subscription) that opens Sectors B, C and D (45 more levels), every crate skin, and the swing guide on every run. Sector A and the daily run are free. There are no ads in Tether & Swing, free or paid.
