Panda Nook is a calm logic puzzle starring Panda, an original red panda looking for a nook of their own. The board is split into colourful nooks, each with its own outline and texture as well as its colour, and the job is to seat one panda in every row, every column and every nook without any two touching. The campaign runs to 1000 boards, from a guided 4x4 that teaches each rule on the board itself up to 9x9 grids late on. Every board was generated backwards from a finished answer and confirmed by a separate solver to have exactly one solution, so no square ever needs a guess. New solving ideas arrive one at a time, each with a short lesson the first time it is needed, and the Hint explains the next sure square in words instead of filling it in. A wrong panda costs one of three tries, crosses are free, and a daily nook with a streak opens after ten solved boards.
