Eric Fox's Puzzles

     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

       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

       Place a number from 1 to N into each cell so that each row and column contains every number from that range with no repeats, where N is the side length of the grid. A clue outside the grid represents how many cells in the corresponding row or column contain a larger number than all cells before it in that row or column from the direction of the clue.

       Place a number from 1 to N into each cell so that each row and column contains every number from that range with no repeats, where N is the side length of the grid. Two of the same number may not appear in diagonally adjacent cells. A clue represents the value obtained by applying an operation iteratively on the numbers in the region the clue is in. If no operation is given, it may be any of +, -, ×, or ÷. Subtraction and division in regions with more than two numbers are handled by taking the largest number and subtracting/dividing all the others. Solve online

         Shade some tetrominoes of cells so that no two tetrominoes touch each other orthogonally. Clued cells cannot be shaded, and a clue means that the first tetromino seen in a straight line in the indicated direction is of the shape associated with that letter. Solve online

       Draw a non-intersecting loop through the centers of all empty cells. No straight line segment may be more than two cells in length. Solve online

       Draw rectangular loops through the centers of cells so that every cell gets used. The sides of different rectangles may intersect each other, but not turn at their intersection or otherwise overlap. When a loop goes through a black circle, it must turn and travel straight through the cells on either side. When a loop goes through a white circle, it must go straight through and turn in at least one of the cells on either side. Solve online

       Draw a non-intersecting loop through the centers of all cells. A number in a region represents the number of cells occupied by the largest continuous loop segment within the region. Solve online

      Here we have another genre I've created! This one isn't totally different from existing ones, but it's different enough, in my opinion, to not be considered just a variant.      Draw a non-intersecting loop through the centers of all unshaded cells. No two adjacent regions may be visited by the loop the same number of times. A number in a region indicates how many times it’s visited by the loop. Solve online

       Shade some cells so that all shaded cells form one orthogonally connected area and each orthogonally connected area of unshaded cells is in the shape of a square. Cells with black circles must be shaded, and cells with white circles must not be shaded. No 2x2 region may be entirely shaded. Solve online

       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. Solve online
