About this game

Five sudoku variants in one app: Classic, Killer, X, Hyper and Jigsaw. Four difficulty levels, a new daily challenge every day, and every puzzle playable offline.

Whether you are solving your first grid or hunting an expert-level chain, this is a sudoku game built for logic - clean grids, smart hints, and no timer pressure unless you want it.

FIVE SUDOKU VARIANTS

• Classic Sudoku - the 9x9 grid where every row, column and box holds 1-9 exactly once
• Killer Sudoku - sum cages add arithmetic to the logic, no given digits to start from
• X Sudoku - both diagonals must also hold 1-9, opening up new deduction chains
• Hyper Sudoku - four extra overlapping regions demand advanced technique
• Jigsaw Sudoku - irregular shapes replace the 3x3 boxes and change every strategy

Each variant has Easy, Medium, Hard and Expert difficulty, so you can grow into it.
