One ghost per region. One per row. One per column. And none of them touching, not even at the corners. That is the whole rule set. No numbers, no arithmetic, nothing to memorise. Boodoku is a grid logic puzzle with friendly ghosts in it, and every board can be solved by pure deduction. NO GUESSING, EVER Every board has exactly one answer, and you can always reach it by reasoning. Work out where a ghost cannot go, and the square where it must go appears on its own. SPOOKY, NOT SCARY Cute ghosts, soft colours and nothing that jumps out at you. The atmosphere is there, the jump scares are not. AT YOUR OWN PACE No timer and nothing counting down. Small boards for a short break, bigger ones when you want to sit with a problem. PLAYS WITH NO SIGNAL Works on the plane, on the underground, in the hills with one bar of nothing. No account, nobody to wait for. NO NUMBERS, NO ARITHMETIC If you like sudoku but not the counting, this is the same kind of thinking without a single digit on the board.
