Color Screw 3D

Color Screw 3D hands you a mechanical structure covered in colored bolts and one rule: every box only holds three. That limit is what turns unscrewing into a puzzle instead of a chore - pull the wrong bolt first and you can fill a box before the matching pieces you actually need have anywhere left to go.

Rotating the structure before you start removing anything is worth the extra few seconds, since bolts hidden on the far side change which color needs clearing first. Physics takes over once a piece loses its support, so a badly ordered sequence can knock loose parts you weren't ready to deal with yet. Reading the whole structure before touching a single bolt saves more time than it costs.

How to play

Rotate the structure to see every bolt before you start unscrewing, since some colors are hidden on the far side. Tap or click a bolt to remove it and send it to a box of matching color - each box holds only three, so plan which color to clear first rather than removing bolts in whatever order you see them. Watch for parts that fall away once their support is gone; a badly timed removal can expose a new problem underneath.

Controls

On PC, hold the right mouse button and drag to rotate the structure, and click a bolt to unscrew it. On mobile, swipe to rotate 360 degrees and tap a bolt to unscrew it.
