Featured Puzzle: Stone on Stone #1
As you might have noticed by now, I love the various cell-shading puzzles. Today, we’re taking a look at another Nikoli creation – Stostone. In English, it’s generally known as Stone on Stone.

Featured Puzzle: Sukaku #1
Sukaku is an interesting variant of Sudoku. Rather than the standard format of revealing a few known numbers, you are instead given pencilmarks. As a matter of fact, another name for this puzzle is Pencilmark Sudoku. Otherwise, normal Sudoku rules apply. Fill the grid with 1-9 in such a way that no row, column, or 3×3 region contains a duplicate.
Featured Puzzle: Tetoron #1
When Tetris was in its heyday on computers, I was in high school. I’m not sure how many games I’ve played, but I definitely got to the point where I started seeing tetrominoes everywhere. Maybe the inventor of Tetoron, Nishiyama Yukari, was also a fan. In this puzzle, you must divide the grid into tetromino shapes.
Featured Puzzle: Tile Paint #1
Similar to a nonogram, Tile Paint puzzles reveal a picture. Each region must be fully shaded, or empty. Numbers indicate the total of shaded cells in their row or column.
