Hakoirimusume or Demoiselle(Sheltered Daughter) is a sliding block puzzle.
It challenges a player to bring the Daughter placed deep in the house, i.e. the block in the middle of the highest row, to the exit of the house situated in the middle of the lowest row, removing obstacles on the way.
A player can choose among seven different starting positions according to his/her skill.
A player choosing the position requiring the most developed skill can have, by clicking on “To Hint”, an instruction on two types of solutions.
One is the shortest possible solution with 81 moves.
The other is an example of other solutions and helps to understand how to move each block with a distinct aim.
