#428 - Irunuri

     Shade some cells so that all shaded cells form one orthogonally connected area. Numbered regions must contain the indicated amount of shaded cells. The shaded cells within a region must have 180° rotational symmetry around the region's center. No 2x2 area may be entirely shaded.

    Do the shaded cells have the symmetry, or do the regions themselves?

#41 - Tentaisho / Star Battle Hybrid

Image
      This puzzle is mostly a proof of concept, which is why it's so small and isn't very logically interesting. I've seen several attempts at a Tentaisho Star Battle hybrid, but I've seen no successful ones without additional rules. My ultimate goal is a 10x10 one with two stars, but the best I've managed so far is a 6x6 one with one star.      Divide the grid into regions of orthogonally connected cells. Each region must contain exactly one circle and have 180° symmetry around it. Additionally, p lace stars into some cells such that each row, column, and outlined region contains exactly one star. Stars may not touch one another, not even diagonally. Solve online

#300 - My Original Genres

     For my 300th post, I've put together a collection of example puzzles for all of my original puzzle genres. As I create more in the future, this post will get updated. I hope you enjoy!     1.  Ovotovata  (oh-VOH-toh-VAH-tuh)      Draw a non-intersecting loop through the centers of some cells which visits each shaded region at least once. When the loop exits a clued region in any direction, it must travel in a straight line for exactly the indicated number of cells (turning on the Nth cell, where N is the value of the clue).

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

#437 - Square Jam

     I've created another puzzle genre that I'm excited to share. Here it is: Square Jam!      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

#498 - Double Choco

Image
       Divide the grid into regions of orthogonally connected cells, each containing a connected group of white cells and a connected group of grey cells, with the property that the shape of the white cells is identical to the shape of the grey cells, allowing rotations and reflections. Clued cells must belong to a region containing the indicated number of white cells and the indicated number of grey cells. Solve online
