Eric Fox's Puzzles

      This puzzle was my last-minute entry to Logic Showcase #38 (My Favourite Star Battle Variant). I didn't enter expecting to receive a lot of votes, I just wanted to have entered something !      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. Stars must be in the same positions in corresponding shaded regions. Solve online

    This idea for a hybrid is something I wasn't sure would be possible at all, but it actually wasn't all that difficult to construct and I'm very satisfied with the result.      Place stars into some cells such that each row, column, and outlined region contains exactly two stars. Stars may not touch one another, not even diagonally. Additionally, d raw a non-intersecting loop through the centers of all empty cells which passes through each region exactly twice. Solve online

       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. Clued cells cannot contain stairs, and contain arrows indicating all of the orthogonal directions in which a star appears closest to the clued cell. At least one star must appear in the direction of an arrow. Solve online

     Star Battle (Left):      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.      LITS (Right):      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.

      Beginning on June 3rd 2021,  Jeffrey Bardon / IHNN  and I hosted a puzzle context titled Hexagony which lasted one week, consisting of 30 puzzles across 15 genres, each with one puzzle on a square grid and one on a hexagonal grid. Although the contest is now over, the puzzles can still be accessed and solved for fun! Instruction Booklet Puzzle Booklet Contest Results

       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

       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

       Place stars into some cells such that each row, column, and white region contains exactly N stars. The value of N is given outside the grid. Grey regions may contain any number of stars. Stars may not touch one another, not even diagonally. Solve online

    It took a very long time to get this puzzle to work exactly as intended, but I'm thrilled with how it turned out. Enjoy!      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. Additionally, place stars into some unshaded cells such that each row, column, and outlined region contains exactly two stars. Stars may not touch one another, not even diagonally. Solve online

      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
