Here’s a puzzle from my preparation for WPC 2019 that I don’t believe I’ve posted yet. It’s also sort of a practice puzzle for the upcoming first round of the 2020 Puzzle GP, which features the variant Terra XX.
Rules Place numbers in the empty cells, from the range 0-9. Same numbers can’t be adjacent (but may touch by a corner). Wherever four cells meet at a vertex (marked by a black dot), the sum of the numbers in those cells must be 10.
Seasonal. I’m still a novice at the black mass art. You should check out the work of dark master @4G_bms, e.g. this one or this one.
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.
