Eric Fox's Puzzles

       Divide the grid into square regions of orthogonally connected cells. A number indicates the side length of the square it’s in. Region borders may not form any four-way intersections. Solve online

       Shade some cells so that no two shaded cells are orthogonally adjacent and the remaining unshaded cells form one orthogonally connected area. Each circle must touch exactly one shaded cell. Three consecutive shaded cells within the same row or column may not be evenly spaced. Solve online

       Divide the grid into rectangular regions of orthogonally connected cells. Each letter represents a different constant positive integer. Each region must contain exactly one clue, the value of which represents the number of cells in the region. Solve online

       Shade some cells to form a non-intersecting path which does not touch itself orthogonally. A black circle marks an end of the path. Each orthogonally connected area of unshaded cells must be exactly four cells in size. Clues cannot be shaded, and contain the letter associated with the tetromino shape of their unshaded area.

       Shade some cells to form a non-intersecting path which does not touch itself orthogonally. Circles mark the ends of the path. Exactly one orthogonally connected area of unshaded cells must exist of each size from the range given outside the grid. Cells with numbers cannot be shaded, and represent the size of the area they’re in. Solve online
