Regatta: Daily Mid-loop

Goal: chart one closed course through every black midpoint buoy.

The course travels horizontally or vertically through cell centres. It never crosses, branches, or visits a cell twice.

At every black buoy the course goes straight. The buoy is exactly halfway between the two turns at the ends of that straight segment.

Not every cell has to be part of the course.

Play: drag between neighbouring points to draw a leg. Tap or click an existing leg to erase it.

Keyboard: focus the board and use Arrow keys to move. Shift+Arrow draws. Ctrl/⌘+Z undoes.

Perfectly on course
