#183 - Doppelgänger Kropki (Pairs) & Masyu

     Kropki (Pairs) (Left):

    Place a number from 1 to N into each cell so that each row and column contains every digit with no repeats, where N is the side length of the grid. Pairs of orthogonally adjacent cells marked with a black dot must contain numbers with a 1:2 ratio. Pairs of orthogonally adjacent cells marked with a white dot must contain consecutive numbers.

    Masyu (Right):

    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.

#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

Image
     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

#160 - Matryoshka Fillomino

Image
     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.
