HEADSTACK

HEADSTACK

Stack blocks with your head.

No keyboard. No mouse. No controller. Your webcam watches your face, and your head does all the work. Tilt to slide, look up to spin, nod to drop. It sounds easy. It is not.

There is no Hold. No second chances. The pieces come, and you deal with them — one neck movement at a time.

HOW TO PLAY

- Tilt your head left / right — move the piece (tilt further to move faster)

- Look up — rotate (return to center before rotating again)

- Nod down — soft drop (keep nodding to keep dropping)

- Open your mouth — SLAM the piece straight down (yawning is dangerous)

Before each game, look straight at the screen for a second. HEADSTACK learns your neutral pose, so it works whatever angle your webcam is at.

KEYBOARD MODE

No webcam? Play the classic way:

← → move · ↑ / X rotate · Z rotate back · ↓ soft drop · Space hard drop · P pause

TIPS

- Sit 50–80 cm from the screen with light on your face

- Chrome or Edge on a desktop/laptop works best

- Gentle movements are enough. Please don't whip your neck around.

REQUIREMENTS
