Introduction
Sudoku is a popular puzzle game that requires players to fill a grid with numbers in a way that satisfies certain rules. Over the years, the game has evolved from a pen-and-paper activity to one that can be played online. In this article, we will discuss Sudoku online with pencil marks in 2023.
What are Pencil Marks in Sudoku?
Pencil marks are used to help players keep track of the numbers they are considering for each cell. In traditional pen-and-paper Sudoku, players would write these marks in the corners of the cells. In online Sudoku, pencil marks are usually entered using a separate tool or feature.
Why Use Pencil Marks?
Pencil marks help players avoid mistakes and save time. By keeping track of the possible numbers for each cell, players can quickly eliminate options and focus on the most likely candidates. This reduces the risk of making errors and allows players to solve the puzzle more efficiently.

Players can access puzzles from anywhere with an internet connection, and they do not have to worry about carrying around a pen and paper. Second, online Sudoku often includes helpful features such as automatic pencil marks, hints, and error-checking. These tools can help players improve their skills and solve puzzles faster.
