The site had the following in the web page, "To interact with the boxes of the grid, simply click the left mouse button." I noticed that the web page stated " Different modes of interactions are available ." They also stated " Default mode selected in the upper right lets you fill normally sudoku grid. To fill a box, click it once and then click once on the number to insert. The mode Reversed marking. Works like the marking mode, but in this case, all the small numbers are marked except the one selected first." The meta header had sudoku as the first keyword. This keyword was followed by sudokus, sudocu, and puzzle which isn't as urgent as sudoku. The other words the site uses is puzzles. grid is also included and could not be seen by search engines.
