       Shade one tetromino of cells in each region so that all shaded cells form one orthogonally connected area. Two tetrominoes of the same shape may not share a bold border, counting rotations and reflections as the same. No 2x2 region may be entirely shaded. Solve online

     Shade some cells so that no two shaded cells are orthogonally adjacent and draw rectangular loops through the centers of the remaining empty cells so that every remaining empty cell gets used. The sides of different rectangles may intersect each other, but not turn at their intersection or otherwise overlap. Clues cannot be shaded, and represent the number of shaded cells in a straight line in the indicated direction. Solve online

       Shade some cells so that all shaded cells form one orthogonally connected area. Clues cannot be shaded, and represent the lengths of the blocks of consecutive shaded cells in the (up to) eight cells surrounding the clue. No 2x2 region may be entirely shaded. Solve online

       Disclaimer: Solving this puzzle requires specialized knowledge in Heyawake penalty theory.    Shade some cells so that no two shaded cells are orthogonally adjacent and the remaining unshaded cells form one orthogonally connected area. Numbered regions must contain the indicated amount of shaded cells. A line of consecutive unshaded cells may not cross more than one bold border. Solve online

     Pomoro, originally called Pomoyo, is another genre I invented. It's a region division puzzle conceived in early November of 2020. This was the first Pomoro puzzle that I created!      Divide the grid into regions of orthogonally connected cells, each containing exactly one circle. A clue in a circle indicates the number of cells in its region. Numbers represent the amount of region borders that appear in a straight line in the indicated direction. Borders must separate two different regions. The edge of the grid does not count as a border.     The rule regarding clues inside of circles was added later on. This puzzle has no such clues.

       Draw a non-intersecting loop through the centers of all cells. The loop must turn on black circles and travel straight through the cells on either side. The loop must go straight through white circles, and turn in at least one of the cells on either side. Solve online

     I saw one of these on IHNN's blog and have wanted to make one myself for a while, so here it is!      Shade some cells so that each orthogonally connected area of shaded cells is in the shape of a square and the remaining unshaded cells form one orthogonally connected area. Clued cells cannot be shaded, and represent the total size of the shaded squares that share an edge with the clue. If a clue has no number, it must share an edge with at least one shaded square. Two shaded squares of the same size may not have a vertical or horizontal line of unshaded cells between them, unobstructed. Solve online

       Shade some cells so that all shaded cells form one orthogonally connected area. Clues cannot be shaded, and represent the lengths of the blocks of consecutive shaded cells in the (up to) eight cells surrounding the clue. No 2x2 region may be entirely shaded. Solve online

       Divide the grid into regions of orthogonally connected cells. Two regions of the same size may not share an edge. Clued cells must belong to a region containing the indicated number of cells. Solve online

     This is a Fillomino puzzle that works and has a different solve path no matter how many layers you chop off the edges.      Divide the grid into regions of orthogonally connected cells. Two regions of the same size may not share an edge. Clued cells must belong to a region containing the indicated number of cells.

       Draw a non-intersecting loop through the centers of all cells. The loop must turn on black circles and travel straight through the cells on either side. The loop must go straight through white circles, and turn in at least one of the cells on either side. Solve online

       Shade some dominoes of cells so that every region contains exactly two shaded cells, and d raw a non-intersecting loop through the centers of all unshaded cells . No two shaded dominoes may share an edge. Solve online

       Place lights in some cells so that every cell is illuminated. Lights illuminate the cell they’re in as well as all cells seen in a straight line horizontally or vertically, not obstructed by a black cell. Lights may not illuminate each other or be a knight’s move apart. Clues represent the number of lights in the (up to) four cells surrounding the clue. Solve online

       Draw a non-intersecting loop through the centers of some cells that passes through every circle. The loop must turn on black circles and travel straight through the cells on either side. The loop must go straight through white circles, and turn in at least one of the cells on either side. Solve online

       Shade one tetromino of cells in each region so that all shaded cells form one orthogonally connected area. Two tetrominoes of the same shape may not share a bold border, counting rotations and reflections as the same. No 2x2 region may be entirely shaded. Solve online

       Shade some cells so that all shaded cells form one orthogonally connected area. Clues cannot be shaded, and every orthogonally connected area of unshaded cells contains exactly one clue, the value of which represents the size of the area. No 2x2 region may be entirely shaded. Solve online

        This is one of the puzzles I made for PolmanPoppins for a 2020 Secret Santa event.      Shade some cells so that all shaded cells form one orthogonally connected area. Regions with numbers must contain the indicated amount of shaded cells. There may not exist a run of more than three consecutive shaded or unshaded cells horizontally or vertically anywhere in the grid. Solve online

       This is one of the puzzles I made for PolmanPoppins for a 2020 Secret Santa event.      Place stars into some cells such that each row, column, and outlined region contains exactly N stars. The value of N is given outside the grid. Stars may not touch one another, not even diagonally. Solve online
