The logic game Boodoku invites you to use deduction and carefully place shy ghosts in the rooms of an ancient mansion. Place exactly one spirit in each individual zone so that they do not intersect on the common horizontal and vertical lines of the grid. Remember the strict rule of distance, exclude contact of creatures even diagonally, and methodically mark empty cells to narrow the search area. Solve all the hand-crafted stages without any fuss or rush and earn gamer points in Boodoku.
