INFINIDOKU

The infinite scrolling grid contains a full sudoku puzzle, that wraps around both horizontally and vertically. Each row of nine digits, column of nine digits, and heavy-bordered square of nine digits must contain the numbers 1 through 9 once and only once. Click on a cell to highlight it or use the arrow keys to move the highlight around the grid. Backspace or delete will clear the cell. Use the number pad or the number keys to enter numbers into the grid.
