Thomas Snyder (aka Dr. Sudoku) is a two-time World Sudoku Champion and five-time US Puzzle Champion, as well as the author of several books of puzzles. His puzzles are hand-crafted, with artistic themes, serving as a kind of “cure for the common sudoku.” Each week he posts a new puzzle on his blog, The Art of Puzzles. This week’s prescription deals with Tetromino Minesweeper, a challenging variation on the familiar logic puzzle game.

I’ve been experimenting with -omino puzzles this week, and have these Tetromino Minesweeper puzzles to share. While they capture a lot of the logic that you’re probably used to from countless hours playing Minesweeper, having to place connected sets of mines (that do not touch each other, not even diagonally) allows for some tricks that you won’t find in the standard game. Enjoy!

Rules: Place the 7 tetromino shapes into the grid; the shapes may be rotated but cannot be reflected. The numbers in the grid indicate how many of the adjacent cells (including diagonally adjacent cells) contain pieces of the tetrominoes. The tetrominoes cannot sit on the given numbers, and cannot touch even other, not even diagonally.
