What is sudoku 4 x 4?

Sudoku 4 x 4, also known as mini Sudoku, is a beginner-level version of the popular Sudoku puzzle game. The puzzle is played on a 4 x 4 grid, with each row, column, and 2 x 2 subgrid containing all the numbers 1 to 4. The objective of the game is to fill in the grid with the correct numbers without repeating any number in the same row, column, or subgrid. Compared to standard Sudoku, the smaller grid size and reduced number range makes it easier to solve, making it a great starting point for those who are new to the game. Sudoku 4 x 4 can be played on paper, online, or on mobile apps.
