LOGIC / GOLD
Golden Sudoku
Nine digits, one gold board. Every placement clicks; every locked row rings out.
Board complete.
Click a square, then a digit. Arrow keys move, 1–9 place, Backspace erases, N toggles notes.
How to play
Fill every empty square so each row, column and 3×3 box contains the digits 1–9 exactly once. Placing a wrong digit counts as a mistake but never blocks you — you can overwrite it.
Notes
Turn on Notes to pencil small candidates into a square. They clear automatically when that digit is placed elsewhere in the same row, column or box.
Good to know
Three difficulties, three hints per board, and your game is saved in this browser if you close the tab.
