Sudoku Puzzle: Killer Jigsaw

Five sudoku variants in one app: Classic, Killer, X, Hyper and Jigsaw. Four difficulty levels, a daily challenge in every variant, 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, hints when you need them, and a timer you can hide.

FIVE SUDOKU VARIANTS

• Classic Sudoku - the 9x9 grid where every row, column and box holds 1-9 exactly once
• Killer Sudoku - cage sums add arithmetic to the logic
• 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.

DAILY CHALLENGES IN EVERY VARIANT

• Five daily challenges, one per variant, with a calendar of everything you have solved
• Streak tracking and rewards for coming back
• Global leaderboard, plus friend challenges: send a solved puzzle and race each other's time
• Over 20 achievements, from your first win to clean sweeps and speed runs
• Detailed statistics per variant - solve times, win rate and best runs

PLAY THE WAY YOU LIKE

• Notes for pencil marks, an eraser for quick fixes, and hints when a grid stalls
• Three lives per puzzle - a wrong digit costs a life and never stays on the grid
• Built-in tutorials for every variant, including how killer cages and jigsaw regions work
• Color themes, sound themes, haptic feedback, and dark, light or system mode
• Designed for phone and tablet
• Play completely offline - no connection needed
