Sudoku for everyone - Sudoku Game
About the Game
The game is given a playing field of 9x9 cells. You need to fill in the empty cells with numbers from 1 to 9. You can put the numbers so that in a row, in a column and in a small 3x3 square the number appears only once. You are allowed to make only 2 mistakes. You can make notes in the cells and erase the contents. The current game is saved. The game has several difficulty levels.
Game Mechanics
Sudoku is a logic‑based number puzzle played on a 9×9 grid, subdivided into nine 3×3 boxes. The goal is to fill every row, column, and 3×3 box with digits from 1 to 9, without repeating any number in the same row, column, or box. The puzzle starts with some cells pre‑filled as clues; you must deduce the remaining numbers through elimination and logic only — no math or guessing required. Core mechanics include pencil marks (noting possible candidates in a cell), single candidates (only one number fits), hidden singles (a number appears only once in a row/column/box), and advanced techniques like pairs, triples, X‑Wing, or coloring for harder puzzles. Difficulty increases with fewer starting clues and more complex deductions needed. Most digital versions offer auto‑check (invalid moves highlighted), undo/redo, hints, and timer or move counter for challenge. Unlike action or word games, Sudoku rewards pattern recognition, working memory, and systematic elimination. The satisfaction comes from the gradual uncovering of the solution and the final "click" when all numbers align. Perfect for players who enjoy calm, focused brain training and pure logical deduction
