Sixty

What is Sixty?

Sixty is a fast, original one-button timing game you play right in the browser. A marker sweeps around a ring; a bright arc marks the target window. Tap the moment the marker is inside it and you “ship the frame” — the spin reverses, a new, smaller window appears, and everything speeds up. Hit the centre of the window for a frame-perfect tap and the FPS meter climbs: 30 → 60 → 90 → 120 → 144 → 165 → 240. It's a pure-reflex, “one more try” arcade game with a developer-flavoured skin — you're the event loop, and every window is a frame's budget.

How to play

• Watch the dot sweep the ring. When it enters thewindow, tap — space, any key, or anywhere on the dial.
• Land the tap in the bright centre third for aframe-perfect hit, which bumps the FPS meter up a tier and scores more per frame.
• Every hit reverses the direction, shrinks the next window, and nudges the speed up — so the game gets harder through precision, never through impossible reactions.
• You get one life. Tap while the marker is outside the window, or let it sail clean past, and the run ends.

Modifier windows — the twist

Once you're warmed up, special windows start appearing. Each is labelled and telegraphed, so it tests skill, not luck:

• drift — the window slowly slides as you line up the tap.
• debounce — it takes two taps inside a wider window; miss the second and it's over.
• async — a normal hit, but the marker teleports to a fresh angle afterwards to reset your rhythm.

Modifier windows are worth double.

The goal — how to score and “win”

There's no finish line: Sixty is a high-score chase. Your score is the number of frames you ship before you drop one, and a great run is about three things:

• Survive — never miss; a single dropped frame ends it.
• Climb — chain frame-perfect taps to push the FPS meter toward 240.
• Bank — the higher the meter, the more each frame is worth.

Your best score, top speed, and longest perfect streak are saved on this device — the only real win condition is beating them.

Tips

• Aim for the centre of the window, not just anywhere inside it — perfects are where the score is.
• The direction flips on every hit; trust the window position, not a rhythm.
• On modifier windows, read the label first — drift, debounce and async each want a different tap.
