Dive into a calm ocean of logic grids with Sharkdoku! Brought to you by DIGITALKREEDA, this premium offline puzzle experience reimagines classic sudoku and constraint satisfaction games into a fresh, aquatic brain workout.

Sharkdoku: Logic Sudoku Puzzle is a beautifully handcrafted brain teaser game where every shark needs its own space. Place exactly one shark in every row, every column and every coloured reef. Simple to learn, surprisingly deep to master and completely playable offline.

If you love sudoku, logic puzzles and brain teasers, this is your next daily habit.

🦈 HOW TO PLAY

- One shark per row
- One shark per column
- One shark per coloured reef region
- Sharks are territorial: no two sharks may touch, not even diagonally

That's it. Three rules, infinite deduction. There is always exactly one solution, and you can always find it with pure logic. No guessing required.

🌊 FEATURES

- more than 2000 of handcrafted logic puzzle levels
- Difficulty that grows with you, from a gentle start to boards that will genuinely test you
- Smart hint system that explains the reasoning instead of just handing you the answer
- Clean, relaxing ocean art with soft colours and satisfying feedback
- Small download size, runs smoothly on older phones
- Works in portrait, one-handed, perfect for the commute

🧠 A REAL BRAIN WORKOUT

Sharkdoku is a brain training game disguised as a relaxing puzzle. Every board is a constraint problem: eliminate the squares that break a rule, narrow the possibilities, and let the solution reveal itself. It sharpens deduction, pattern recognition, planning and concentration, the same mental muscles classic sudoku and minesweeper build, in a fresh format.

Perfect for adults and kids alike. If number sudoku feels stale, this is the same satisfying logic loop with a completely different shape.

🌍 A QUIET PLACE TO THINK

No leaderboards shouting at you. No streaks punishing you for missing a day. Just you, a grid, and a small school of very particular sharks. Solve a board in two minutes on your break, or lose an hour to the hard levels, both are the right way to play.

Free to download. Free to play. Free forever.

Download Sharkdoku, place your first shark, and find out how good your logic really is.
