About the game
A browser adaptation by Zarocer.
Place the digits 1 through 9 once each in the 3×3 square. All three rows, all three columns and both main diagonals must total 15. Fixed clues stay in place. The center is always 5 in a valid square; think about the remaining pairs as you fill the surrounding cells.
Controls
Click or tap picks numbers and cells; type 1–9 for a selected cell. Delete or Backspace clears; Z undoes; H requests a compatible hint. Restart asks for confirmation; Escape closes a dialog or returns to the menu
Choose a number and a cell
Use the visible number bank and select a cell, or select a cell and enter a digit with the keyboard. Clear removes an editable entry and Undo restores the previous board. Hint fills one compatible cell. A completed line with the wrong sum is highlighted so you can revise it.
Small boards, local records
Difficulty changes the starting clues. The daily challenge is dated, with a finite set of eight Lo Shu orientations; this is not an unlimited puzzle library. Continue restores the unfinished board in this browser. Hint-assisted results and unassisted personal bests are distinguished in the native statistics.
