#93 - Aqre

    This is another proof of concept puzzle, with the goal of creating a very large unclued region. This example has a 9x9 "hole" in the middle. I believe 10x10 shouldn't be too difficult to pull off, but I think far larger holes are possible.

    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.

    There is now one with a 13 by 13 hole on Puzzle Square JP: https://puzsq.jp/main/puzzle_play.php?pid=15327.

      Wow! I'm pretty sure holes of arbitrary sizes have been proven possible but this is the largest I've seen in a legitimate non-proof-of-concept puzzle by far. Thanks for sharing!

#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

     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).

     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

       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. Clues represent the number of lights in the (up to) four cells surrounding the clue. 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.
