Boodoku: Spooky Logic Puzzle

HALLOWEEN IS HERE - Boodoku is dressed for the season.

One ghost per row. One per column. None of them touching.

Boodoku is a logic puzzle with a friendly haunting. Place a ghost in every row, every column and every coloured region, and make sure no two ghosts end up side by side. No arithmetic, no guessing, no timers. Just clean deduction and a board that rewards patience.

HOW IT WORKS
- Tap once to mark a square you have ruled out
- Tap again to place a ghost
- Every row, every column and every region holds exactly one
- No two ghosts may touch, not even diagonally
- Every puzzle has exactly one solution, and you can always reason your way to it

A NEW PUZZLE EVERY DAY
One fresh board daily, the same for everyone. Keep your streak going, or take the day off. Nothing here punishes you for stopping.

BUILT FOR THINKING, NOT REFLEXES
No countdown. No lives to lose. No moves running out. Put the phone down halfway through a board and it will be waiting exactly as you left it.

WHEN YOU GET STUCK
Hints explain the technique instead of handing you the answer, so the next puzzle is easier on your own. Undo as often as you like.

PLAYS FULLY OFFLINE
No connection needed. Solve on a plane, on the train, in a waiting room or anywhere the signal drops.

FRIENDLY SPOOKY, NOT SCARY
Soft colours, cheerful ghosts and a calm soundtrack. Suitable for all ages.

Free to download and play.

Can you clear the board without a single guess?
