Star Chart

charting the heavens…

A faded star-chart waits in the scriptorium. Set each glyph so every row, every column and every ward of nine holds all nine marks but once.

How to play

Tap a cell, then tap a glyph to set it. Each row, column and 3×3 ward must hold all nine glyphs exactly once.
Marks lets you pencil small candidate numbers into a cell. Tap Marks again to go back to writing glyphs.
Erase clears a cell. Undo steps back. Hint reveals one correct glyph.
A wrong glyph glows red and costs a flaw. Five flaws and the chart is lost — but you can retry at once.
Desktop: arrow keys move, 1–9 write, Del erases, P marks, U undo, H hint, Esc menu.

Each glyph answers to a catalogue number. Pencil marks are always written as numbers.

The chart rests.
