TETHER: Swing & Fly
Rope Swing Physics Arcade
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
One seeded course a day, the same one for everyone on Earth, with a wall of pure black closing from the left the whole way. No ads, no energy timers, no account.
A wall of pure black is already moving in from the left. It is leashed to the furthest point you have ever reached, so the gap only opens while you keep going — stall for a moment and it closes over you. There are no levels here to survive to. There is only the next anchor.
TETHER is one button and a real line. When you catch an anchor, the sweet spot is drawn for you: a glowing arc laid over your actual swing circle. Come round a full swing, carry speed into that arc, and let go inside it — that is a Perfect. Speed bursts, time stretches for a beat, and the chain multiplier climbs toward ×10, multiplying distance, grazes and Perfects all at once. Release sloppily and the chain is gone.
Every day the world gets one seeded course. Same course in Seoul as in Sao Paulo, plus three daily missions everyone shares. Your own best run comes back as a ghost and runs it beside you, half a second ahead or half a second behind, which is the only opponent that has ever really mattered.
• THE VOID — a black wall leashed to your furthest point; hesitate and it swallows you
• THE RELEASE ARC — the sweet spot is drawn on your swing circle, not left to feel
• CHAIN MULTIPLIER — up to ×10 across distance, grazes and Perfects
• DAILY COURSE — one seeded course and three missions, identical for every player on Earth
• GHOST — your personal best replays beside you as a rival
• FIVE BIOMES — Dusk, Ember, Verdant, Violet and Ash cross-fade as you travel
• ENDLESS — the course is generated as you play and never repeats
• MOMENTUM PHYSICS — hold to reel in and pump the arc like a playground swing; slack line is free fall
• GENERATED, NOT DRAWN — every sprite and every sound is made procedurally. You are a point of light, not a character
• 10 SKINS — every one earned by playing, none for sale
• 20 LANGUAGES — with full right-to-left support
• GAME CENTER — leaderboards and achievements
• NO ADS, NO ENERGY TIMERS — play for as long as you like
TETHER PRO is one optional purchase. It never touches gameplay, so the leaderboard stays honest.
No account, no sign-up. Everything runs on your device.
