Trichain is a new puzzle type I invented. It is somewhat similar to Nurikabe, but it uses a chain of L-trominoes instead of a continuous wall.
Example puzzle with solution:
Rules:
Numbers must be white, and match the size of their white islands.
Each white island can only contain at most one n...
I decided to make another one of these, because they are fun and this one is rather different.
Can you place all numbers from 1 to 16 into cells, such that the following 8 equations hold? Note that the operator "/" only works for non-remainder division, i.e. you can have "8 / 4" but not "8 / 3". ...
This is a minesweeper puzzle with a tetromino twist. The goal is to place mines in the grid, following a few constraints.
Rules:
A number indicates how many adjacent (including diagonally adjacent) cells have mines in them.
Mines cannot go in numbered cells.
Mines must be grouped into tetromino ...

Black L-trominoes cannot b...

G said H and C did it.
C said D and J did it.
T refused to say anything.
Four of the suspects named one person correctly and one person incorrectly. The fifth s...
Nurikabe and Tapa puzzles have the interesting property that the target shading is identical for both: a fully-connected shaded region with no 2-by-2 blocks. The difference is the cluing, so there seems no reason you can't use both Nurikabe and Tapa clues in a single grid to clue a single shaded ...
