Neck Marble

About Neck Marble

Neck Marble is a tilt-maze against the clock across three hand-built courses — Prism Causeway, Switchback Garden and Aurora Ascent — which teach braking before corners, threading a long S-bend, and managing momentum on a climb, in that order. Tilting your head in two axes tilts the whole board and the marble rolls accordingly.

This is the only game here that uses continuous two-axis head input for physics, and it is by some distance the most demanding one. The marble accelerates at 940 units per second squared up to a 390 cap, with a rolling drag of 1.45 that rises to 4.8 when you return your head to neutral — so centring your head is an active brake, not just an absence of input. Falling into a hole costs you 0.72 seconds of reset, and walls bounce you back at 52 percent of your impact speed, which is enough to matter on a fast approach.

Your best time is stored per device in local storage. Because it is timed rather than endless, the courses reward learning a line and then executing it, which is a different pleasure from the reflex games.

How to play

• Tilt your head in any direction — the board tilts and the marble rolls that way
• Return your head to neutral — heavy drag brakes the marble
• Arrow keys or WASD — the same two-axis tilt
• Reach the goal on each of the three courses; falling in a hole costs 0.72 seconds
• Your best time is saved locally on your device

Tips & tricks

• Neutral is your brake. Drag more than triples when your head is centred, so the fastest way to slow down before a corner is to stop tilting entirely rather than to tilt back.
• Brake before the corner, not in it. This is exactly what the first course is built to teach, and the same line works on the other two.
• Do not fight the walls. A bounce returns 52 percent of your speed, so a marble ricocheting down a corridor is faster than it looks and much harder to stop.
• On the S-bend, take the inside line slowly rather than the outside line fast. The 0.72-second hole penalty costs more than the time any aggressive line saves.
• Small tilts, held. The marble accelerates continuously while you tilt, so a gentle sustained lean builds more controllable speed than a sharp one you have to correct.
• Learn the course before you race it. Your best time is only saved once, so a slow first lap spent finding the line costs nothing and is the fastest route to a good time overall.

Frequently asked questions

How many courses are there?

Three: Prism Causeway, Switchback Garden, and Aurora Ascent, each built around a different skill.

Is Neck Marble free?

Yes, free in your browser with no download.

How do I slow the marble down?

Return your head to neutral. Drag rises from 1.45 to 4.8 when you are centred, so centring is an active brake.

Can I play it on the keyboard?

Yes. Arrow keys or WASD tilt the board the same way.

Is my best time uploaded anywhere?

No, it is stored only in your browser's local storage on this device.
