Monday Mutant 125: Streampunk / Tetra Firma

Shade in tetrominoes such that the black cells are all connected to each other through their edges, and no 2x2 cell area within the grid contains all black cells. No two congruent tetrominoes may share an edge, even if they are rotated or reflected versions of each other. Numbers in a cell indicate the sizes of the orthogonally contiguous groups formed by black cells sharing a corner or an edge with that cell. For example, "3" means that the cell shares a corner or an edge with three black cells, and they form a single group, whereas "1 3" means the cell shares a corner with four black cells which form a group of three cells and a single separate cell. Cells with numbers cannot be black.

Monday Mutant 124: Streampunk

Shade in some cells black such that the black cells are all connected to each other through their edges, and no 2x2 cell area within the grid contains all black cells. Numbers in a cell indicate the sizes of the orthogonally contiguous groups formed by black cells sharing a corner or an edge with that cell. For example, "3" means that the cell shares a corner or an edge with three black cells, and they form a single group, whereas "1 2" means the cell shares a corner with three black cells which form a group of two cells and a single separate cell. Cells with numbers cannot be black.

Monday Mutant 107: Streampunk / Tetra Firma

Shade in tetrominoes such that the black cells are all connected to each other through their edges, and no 2x2 cell area within the grid contains all black cells. No two congruent tetrominoes may share an edge, even if they are rotated or reflected versions of each other. Numbers in a cell indicate the sizes of the orthogonally contiguous groups formed by black cells sharing a corner or an edge with that cell. For example, "3" means that the cell shares a corner or an edge with three black cells, and they form a single group, whereas "1 3" means the cell shares a corner with four black cells which form a group of three cells and a single separate cell. Cells with numbers cannot be black.

March Mutant 31: Streampunk (make room)

Shade in some cells black such that the black cells are all connected to each other through their edges, and no 2x2 cell area within the grid contains all black cells. Numbers in a cell indicate the sizes of the orthogonally contiguous groups formed by black cells sharing a corner or an edge with that cell. For example, "3" means that the cell shares a corner or an edge with three black cells, and they form a single group, whereas "1 2" means the cell shares a corner with three black cells which form a group of two cells and a single separate cell. Cells with numbers cannot be black. Additionally, every outlined region of more than one cell must contain exactly five black cells.

Well, Quantity-Not-Quality Month is over, so I'll need to think of some other excuse for my puzzles being lacking in quality. What if I decided tomorrow to stop posting puzzles on this blog, and to post everything in the universe besides puzzles? That might be a good excuse. Nah, too lazy this year. Guess I'll have to resort to actually making high-quality puzzles.

Regular Monday Mutants will resume in the middle of April!

March Mutant 18: Streampunk / Tetra Firma

Shade in tetrominoes such that the black cells are all connected to each other through their edges, and no 2x2 cell area within the grid contains all black cells. No two congruent tetrominoes may share an edge, even if they are rotated or reflected versions of each other. Numbers in a cell indicate the sizes of the orthogonally contiguous groups formed by black cells sharing a corner or an edge with that cell. For example, "3" means that the cell shares a corner or an edge with three black cells, and they form a single group, whereas "1 3" means the cell shares a corner with four black cells which form a group of three cells and a single separate cell. Cells with numbers cannot be black.

The Print-and-Play edition of my two-player board game Battle of LITS is officially available! Based on a Japanese logic puzzle, Battle of LITS is, among other things, about not having neighboring tetrominoes which are congruent. Nah, don't let my self-deprecation deter you from trying it; I'm actually proud of it. :)

Monday Mutant 97: Streampunk (no dead ends)

Shade in some cells black such that the black cells are all connected to each other through their edges, and no 2x2 cell area within the grid contains all black cells. Numbers in a cell indicate the sizes of the orthogonally contiguous groups formed by black cells sharing a corner or an edge with that cell. For example, "3" means that the cell shares a corner or an edge with three black cells, and they form a single group, whereas "1 2" means the cell shares a corner with three black cells which form a group of two cells and a single separate cell. Cells with numbers cannot be black. Additionally, every black cell must share an edge with at least two other black cells.

Monday Mutant 80: Streampunk / Tetra Firma

Shade in tetrominoes such that the black cells are all connected to each other through their edges, and no 2x2 cell area within the grid contains all black cells. No two congruent tetrominoes may share an edge, even if they are rotated or reflected versions of each other. Numbers in a cell indicate the sizes of the orthogonally contiguous groups formed by black cells sharing a corner or an edge with that cell. For example, "3" means that the cell shares a corner or an edge with three black cells, and they form a single group, whereas "1 3" means the cell shares a corner with four black cells which form a group of three cells and a single separate cell. Cells with numbers cannot be black.

Fillomino-Fillia is over, and MellowMelon is hosting a contest where you can try guess the authorship of each of the 18 puzzles. Check it out!

Monday Mutant 79: Streampunk (all 3's)

Shade in some cells black such that the black cells are all connected to each other through their edges, and no 2x2 cell area within the grid contains all black cells. Numbers in a cell indicate the sizes of the orthogonally contiguous groups formed by black cells sharing a corner or an edge with that cell. For example, "3" means that the cell shares a corner or an edge with three black cells, and they form a single group, whereas "1 3" means the cell shares a corner with four black cells which form a group of three cells and a single separate cell. Cells with numbers cannot be black. A 3 or a clue with a 3 in it has been placed in every white cell that could legally contain one.

Monday Mutant 78: Streampunk

Shade in some cells black such that the black cells are all connected to each other through their edges, and no 2x2 cell area within the grid contains all black cells. Numbers in a cell indicate the sizes of the orthogonally contiguous groups formed by black cells sharing a corner or an edge with that cell. For example, "3" means that the cell shares a corner or an edge with three black cells, and they form a single group, whereas "1 2" means the cell shares a corner with three black cells which form a group of two cells and a single separate cell. Cells with numbers cannot be black.

Before you complain about me featuring a "classic" puzzle type (a modern classic, mind you, but a classic nonetheless), I quote a post of yore: Monday Mutants is a series in which I will attempt to experiment with "mutant" puzzles. These could be existing puzzle types with an unusual change in the rules, hybrids combining elements from multiple puzzle types, or puzzle types neither invented nor popularized by Nikoli. Also remember that in the weeks after that post, I played around with several variants on said "classic" puzzle.
Two of my Cross the Streams puzzles have been published in Akil Oyunlari! I encourage you to get a copy of the magazine so you can see them. Don't let the Turkish language daunt you; the magazine's LiveJournal is devoted to making the puzzles as navigable as possible for English speakers. :)
