Pocong Doku: Logic Puzzle

Over 1,100 verified Star Battle puzzles in a moonlit graveyard. Never a guess: every board has exactly one solution, and every step to it can be proven.

Over 1,100 verified logic puzzles in a moonlit graveyard. Every board has exactly one solution, and you can reach it without a single guess. One pocong per row, per column and per region - and no two of them may ever touch.

That is the entire rule set. Everything after it is deduction.

= HOW IT WORKS =

• Tap a plot once to chalk an X on it: ruled out.
• Tap again to raise a pocong there.
• Exactly one pocong per row, per column and per region.
• No two pocongs may touch, not even diagonally.

If you have played Star Battle, Two Not Touch, Sudoku, Nonogram or Kakuro, you already know the shape of this. The same one-solution logic, a different grid, and Indonesian folklore for company.

= NEVER A GUESS = Every board is machine-checked before it ships. Each one has exactly one solution, and each one can be reached from the clues by pure deduction. However stuck you are, there is always a next move you can prove. You will never flip a coin.

= THREE WAYS TO PLAY =

• Pocong Path: a 60-grave campaign that climbs from 4x4 to 8x8, opening one grave at a time as the boards grow and the clues thin out.
• Practice: pick a size and a difficulty, get a fresh random board. Over 1,000 of them, nothing to unlock.
• Arcade: keep going until your hearts run out. Hearts carry across levels, and the boards get harder the longer your streak runs.

= WHEN YOU GET STUCK = Three hearts absorb your slips, and every board carries a small hint budget: one hint raises a pocong you could have proven, the other chalks out the plots a raised pocong blocks. The budget is capped per board on purpose. Hints nudge you. They do not solve the board for you.

= BRAIN TRAINING THAT RESPECTS YOUR TIME = No timer you cannot pause. No energy meter. No daily streak to lose. A 4x4 grave is a one-minute break; an 8x8 is a proper sit-down brain teaser. Play one board or fifty.

= PLAYS ANYWHERE =

• Every puzzle ships inside the app and plays offline
• No account, no sign-in
• Portrait, one-handed, on phone or tablet
• Bahasa Indonesia and English

The puzzles never need a connection. Ads and the store do.

Start with the guided lesson. The coach plays a real board beside you, so nothing it teaches is a rule the game does not actually enforce.

Pure deduction, start to finish. No luck, no reflexes, no guessing.

The graves are waiting.
