Moon or Sun: Seven Minutes on One Region
One cell stared at me for seven minutes. A single cell. Moon or sun — with the whole region behind it.

Moon or Sun is simple: a click places a moon, the second a sun, the third clears. Each region holds a single type. Moon rows shrink, sun rows expand. Victory means the painting matches the solution. Simple. Until you start.
Challenge: one region in an evening
I set a rule: crack one stubborn region fully, no Hint button. Reset banned too — only clicks back and forth. The region was small, but its shrinking reached across half the grid.
The first five minutes I placed moons confidently. On minute six I saw it: the row mismatched, the line broke. Somewhere above I had mixed the type. I wiped half. Placed suns. The grid sighed and settled straight.
What decides it
Moon or Sun has no speed and no enemies. Only a gaze that learns to see the shrunk line ahead. Now I look at rows first, regions second. I flipped the order — and regions started giving in faster.
Seven minutes on one region. Never touched the hint. The Reset button stayed clean. I sit pleased, as if I built a shelf rather than placed marks in cells.
Try the same: pick one region and finish it with no hint. Seven minutes is a fair score — beat it.
