Xmas Sudoku

Xmas Sudoku is a puzzle game where players must fill in numbers according to certain rules and restrictions. The game features a standard Sudoku grid with some holiday-themed twist. Players start with an empty grid and must fill in numbers from 1 to 9, observing the constraint that each row, column, and 3x3 sub-grid can contain each number only once. Additionally, some numbers are already given to guide players towards the solution. The core mechanic involves using logic and reasoning to narrow down possible values for each cell and make educated guesses. The main objective is to fill in the entire grid correctly, following the rules of Sudoku. The game can be played directly in the browser without any download or registration, making it easily accessible to anyone.
