Description

AI generated by Codex for Shai. An original implementation of six by six Sudoku style number puzzles. Fill each row, column and two by three box with numbers one through six. A seeded generator removes clues only while the puzzle retains exactly one solution. Includes three clue count settings, manual pencil notes, candidate notes, a solution check, one cell hints, keyboard controls and Undo. No external puzzle library is used.

Settings and entered content stay in the current tab only. Reload starts fresh. No account, automatic saving or JSON project backup.

Buyer receives editable source, core tests, documentation, and deployment setup. Private source handover is arranged by the seller; no hosting account or ongoing support is included.
