    Hi! I'm Eric Fox and this is my blog where I post my logic puzzle constructions. I'm also the creator of the Sudoku setting/solving tool f-puzzles.com.

    The puzzles on this blog are always accompanied by the rules, but I also maintain this document for anyone to reference, where I write the rules of every genre and variant that I encounter. Additionally, this post includes the rules and examples of each puzzle genre I've invented.

    Thanks a lot for reading! I hope you enjoy my work!

#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

#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
