LEV     PUZ  

Cave puzzles are also sometimes called Bag puzzles or Corral puzzles.

In this sudoku variant, all the cells with a number form a group - called cave - and they get, in our design, a garden tile. Each number indicates the total number of cells connected vertically and horizontally to the numbered cell including the cell with the number itself.

All the cell that do NOT belong to the cave (= gras zone in our design) must be connected as separate groups to an edge of the grid. They may not be surrounded by the number loop, the cave..

The cells that belong to the cave should be provided with a garden tile as a background and the other cells with a grass zone.
