You can also enter a puzzle # here:
https://www.atksolutions.com/games/sudoku.htmlIt needs to be formatted like this:
https://www.atksolutions.com/games/sudoku.html?puzzle=..7..64...1.5...2.9...3....8...9.....4.2...6...2..1..3..5..4.9..6....7.1...8..6..where you just need to add the ?puzzle=..7..64...1.5...2.9...3....8...9.....4.2...6...2..1..3..5..4.9..6....7.1...8..6.. and the 81 digits, use a period if the digit is unknown.
I am using the Puzzle43 post as an example only:
http://forum.enjoysudoku.com/puzzle-43-t40030.htmlIn addition, if you wanted to play a different puzzle type, you can choose the puzzle style and then play
So if you see a good WindokuX puzzle that you want to try, get the puzzle string and add it to the URL, when the game opens, choose the puzzle style "Window Sudoku X" and click "Play My Puzzle"
