Sudokubum is an online game and app that provides users with an easy and fun way to challenge their problem-solving skills. Players are presented with a 9x9 grid which they must fill with numbers from 1 to 9 in such a way that each row, column and 3x3 mini-grid contains all the numbers from 1 to 9. The goal of the game is to fill the grid in such a way that there are no repeating numbers in any row, column, or 3x3 mini-grid. Players can choose from a variety of difficulty levels, from beginner to expert. Sudokubum also allows users to save their game progress and come back to it later. The game also features helpful hints and tips to help players solve the puzzles.
