Pocong Doku: Logic Puzzle

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.
