About Daily Kakuro (SudokuWiki)
SudokuWiki.org is Andrew Stuart's long-running site about solving strategies for sudoku and related number puzzles. Alongside its solvers and articles it publishes a set of daily puzzles, among them the Daily Kakuro, whose page was created in January 2023.
Kakuro is a crossword made of numbers. Each white run of cells has a clue giving its total, and you fill the run with the digits 1 to 9, without repeating a digit inside a run. The page lets you type numbers straight into the grid, with a timer, undo, a check button, pencil notes and an optional on-screen number pad for phones, or print the puzzle for pencil and paper. Below the grid, a picker shows the solutions of the last 30 days, and Yesterday's Solution is one button away.
The grade follows the day of the week: Gentle on Sunday and Tuesday, Moderate on Wednesday and Saturday, Tough on Friday and Diabolical on Monday and Thursday. Supporters with All-Access can see every grade every day. Each puzzle has a number, such as 5713 for 21 October 2026, and the comments thread below has regular solvers comparing notes.
The new grid does not arrive at midnight: on 22 October the puzzle of 21 October was still being served after midnight UTC, as on SudokuWiki's other dailies, which change at about 03:00 to 03:15 UTC.
It suits number-puzzle fans who have outgrown sudoku and want a daily grid with a clear difficulty ladder.
