Eric Fox's Puzzles

      Here are two Nurikabe puzzles with the same theme: Clues consisting of the numbers 1-8 once each.      Shade some cells so that all shaded cells form one orthogonally connected area. Clues cannot be shaded, and every orthogonally connected area of unshaded cells contains exactly one clue, the value of which represents the size of the area. No 2x2 region may be entirely shaded.

     Over on Logic Masters India a contest I created consisting of 16 Voxas puzzles (a genre of my own invention!) was held from April 2nd to April 22nd of 2022. Big thanks to Deb Mohanty, Prasanna Seshadri, Amit Sowani, and others for help with the back-end stuff and testing! Rules & Info Main Contest Page

      Here's a set of three 9x9 Tapa puzzles I made. Enjoy!      Shade some cells so that all shaded cells form one orthogonally connected area. Clues cannot be shaded, and represent the lengths of the blocks of consecutive shaded cells in the (up to) eight cells surrounding the clue. No 2x2 region may be entirely shaded.

       Shade some dominoes of cells, dividing the grid into regions. Shaded dominoes may not touch orthogonally. Clues cannot be shaded, and every orthogonally connected area of unshaded cells contains exactly one clue, the value of which represents the size of the area. Solve online Solve online Solve online

    Here are two more puzzles of this new genre that I've combined into one post because the first is stupid and the second is small. Neither of the "1" clues are necessary in the first puzzle, but I've included them for aesthetic purposes.        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 Solve online

       Draw a non-intersecting path through the centers of all cells, starting from the S (start) and finishing at the G (goal). Each clued cell must be traveled through on the path’s Nth visit to the region the clue lies within, where N is the value of the clue. Solve online Solve online

       Divide the grid into regions of five orthogonally connected cells so that no regions of the same shape share an edge, counting rotations and reflections as the same. Clued cells must belong to a region with the pentomino shape associated with that letter. Borders must separate two different regions.

      Here are three relatively simple 9x10 Masyu puzzles with symmetrical layouts. The third is a bit trickier than the other two.      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.

       Shade some cells so that all shaded cells form one orthogonally connected area. No 2x2 region may be entirely shaded. Clues outside the grid represent the lengths of the blocks of consecutive shaded cells in the corresponding row or column, in order. A question mark represents one block of an unknown number of cells. An asterisk represents any number of blocks of shaded cells, including none at all.

     Here's a couple of Tapa puzzles I made as a small exercise in antisymmetry.      Shade some cells so that all shaded cells form one orthogonally connected area. Clues cannot be shaded, and represent the lengths of the blocks of consecutive shaded cells in the (up to) eight cells surrounding the clue. No 2x2 region may be entirely shaded.

       Shade some cells so that the remaining unshaded cells form one orthogonally connected area. No 2x2 region may be entirely shaded or unshaded. Circles mark every instance of a cell which is unshaded and orthogonally adjacent to exactly one other unshaded cell. If a circle contains a number, it indicates how many cells are in the straight line of unshaded cells coming out of the cell with the circle, including itself. Solve online Solve online

      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

     Shade some cells to form a non-intersecting path which does not touch itself orthogonally. Circles mark the ends of the path. Exactly one orthogonally connected area of unshaded cells must exist of each size from the range given outside the grid. Cells with numbers cannot be shaded, and represent the size of the area they’re in. 5x5 -  Solve online 6x6 -  Solve online 7x7 -  Solve online 8x8 -  Solve online

     Draw a non-intersecting loop through the centers of some cells that passes through every circle. The straight line segments coming out of a white circle must have equal length, while the straight line segments coming out of a black circle must have different lengths. A clue in a circle represents the sum of the lengths of these two line segments. Solve online 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).
