Sudoku by Thomas Snyder

[This puzzle comes from the 2022 US Sudoku Grand Prix round written entirely by me. This puzzle demonstrates another visual approach to an “eight” theme. While there are no 8s in the grid, all the givens appear in clear two by four block groups which is a pattern that sets up some nice if easy geometric deductions.]

    dear web manager,i want to ask if it is possible to make every visitor could know they finish one puzzle or not at the puzzle select ground, so dont need to click into it to know. I mean i see this web site remembers every thing i input.

      Right now there is no connection between the website and the Penpa-Edit digital solving tool, so we cannot display the status together. There is a separate way to mark finished puzzles so you can remember.
