Sudoku

Sudoku is at Elaria Venn's number nook, kept by Elaria Venn.

• Fill the grid so every row, every column, and every 3×3 nook holds the digits one through nine exactly once.
• Set a difficulty before you start. Harder boards give you fewer starting digits, not different rules.
• There is a shared daily puzzle. Once you have finished it, the game serves generated boards so you can keep playing.

• Scan for the digit with the most placements already on the board — it is usually the one with a forced square somewhere.
