Yet another new puzzle type on puzz.link – many thanks to Lennard Sprong for this and other contributions. I made this puzzle to announce the addition.
Rules Draw a loop from cell center to cell center. Black clues must be outside the loop, while white clues must be inside. Furthermore, Numbers indicate the total number of straight segments in the given direction.
Here’s a Slither Link puzzle with a restrictive theme, that I found with computer assistance, after failing for a while at constructing one by hand. The idea is due to @RainedMirror from the Puzzler’s Club discord. (If you’re interested in puzzle discussions, check the LMI thread for the recent contest for information on how to join.)
Here’s a new (?) Sudoku variant. Inspired by Sudoku N from the upcoming Sudoku Mahabharat. The 6×6 example there also solves uniquely by these rules.
Rules Solve as a regular Sudoku. Some pairs of numbers are friends. Dots mark all spots where two friends are next to each other.
I played around with what I thought were the rules to Oasis today, and came up with this variant.
Rules Shade some cells, to leave a connected area of unshaded cells that includes all given numbers and doesn’t cover any 2×2 square. Some shaded cells are given. Numbers indicate how many other numbers can be reached through unshaded, unnumbered cells.
Example (a poor example: shaded cells can be adjacent)
Just a tiny puzzle that I made as an example for the croco WPC preparation series. It was a bit too hard as an example; the type seems inherently hard.
Rules Place some lamps in the empty cells around the grid, with brightness 0 to 3. The lamps shine horizontally, vertically and diagonally in eight directions. In each direction, they illuminate as many cells as they are bright. Numbers inside the grid indicate how many lamps illuminate the corresponding cell.
The WPC instruction booklet has an example.
Here’s something new, though I wouldn’t be entirely surprised if someone did this before. There’s an example below.
Edit The example was buggy, should be fixed now.
Rules Place some light sources and walls. Light sources go on grid vertices, but not on the border. Walls go on grid lines and must not touch light sources. Numbers outside the grid indicate how many light bulbs illuminate the adjacent edge in total, where a light bulb that illuminates the entire edge counts for 1 (regardless of distance), a light bulb that illuminates the edge partially counts for the corresponding fraction.
Here’s a puzzle for one of the types on the Keller round, with superimposed puzzles.
Rules Solve the left grid as a Mosaik. That is, shade some cells, such that each number indicates the number of shaded cells in the surrounding cells, including the cell itself (so, 9 is the maximum clue). Solve the right grid as a Magic Labyrinth with digits from 1 to 3. That is, place digits 1, 2, 3 in some cells such that every row and column contains each digit exactly once, and walking along the labyrinth from outside to inside, you visit digits in the repeating order 1,2,3,1,2,…, starting with 1.
The two puzzles interact: Whenever a Mosaik clue is shaded, copy that clue to the Labyrinth in the corresponding position.
