Monday Mutant 130: Cross the Streams (domino)

Shade in dominoes 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 to the left of a row or above a column represent the groups of consecutive black cells which are in that row or column. For example, a clue of "3" means the row or column has three consecutive black cells, and a clue of "3 1" means that the row or column has a group of three consecutive black cells followed by a single black cell, separated by at least one white cell. A question mark (?) represents a group of consecutive black cells whose size is unknown; an asterisk (*) represents any number of unknown groups of black cells, including none at all.

Inspired by this Nurikabe puzzle.

Monday Mutant 129: Streaming Content / Tetra Firma

Shade in tetrominoes in simultaneous accordance with the rules of Streaming Content and the rules of Tetra Firma. (As the grid isn't partitioned into regions, the rule of Tetra Firma that every region contains one tetromino is waived.)

Is it possible to create a 10x10 puzzle with these rules and only 4's as givens? I don't doubt it, but I lack the patience to do so at this time. Maybe one of my clever readers can accomplish it. :)

Monday Mutant 128: Cross the Streams

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 to the left of a row or above a column represent the groups of consecutive black cells which are in that row or column. For example, a clue of "3" means the row or column has three consecutive black cells, and a clue of "3 1" means that the row or column has a group of three consecutive black cells followed by a single black cell, separated by at least one white cell. A question mark (?) represents a group of consecutive black cells whose size is unknown; an asterisk (*) represents any number of unknown groups of black cells, including none at all.

Monday Mutant 127: Cross the Streams / 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 to the left of a row or above a column represent the groups of consecutive black cells which are in that row or column. For example, a clue of "3" means the row or column has three consecutive black cells, and a clue of "3 1" means that the row or column has a group of three consecutive black cells followed by a single black cell, separated by at least one white cell. A question mark (?) represents a group of consecutive black cells whose size is unknown; an asterisk (*) represents any number of unknown groups of black cells, including none at all.

Monday Mutant 126: Bridged Series (prime/composite)

In this Bridged Series puzzle, the prime numbers 2, 3, 5, and 7 are represented by P, and the composite numbers 4, 6, and 8 are represented by C. The rules are otherwise unchanged.

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 123: Cross the Streams / Tetra Firma (inverted)

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 to the left of a row or above a column represent the groups of consecutive white cells which are in that row or column. For example, a clue of "3" means the row or column has three consecutive white cells, and a clue of "3 1" means that the row or column has a group of three consecutive white cells followed by a single white cell, separated by at least one black cell. A question mark (?) represents a group of consecutive white cells whose size is unknown; an asterisk (*) represents any number of unknown groups of white cells, including none at all.

Monday Mutant 122: Cross the Streams / 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 to the left of a row or above a column represent the groups of consecutive black cells which are in that row or column. For example, a clue of "3" means the row or column has three consecutive black cells, and a clue of "3 1" means that the row or column has a group of three consecutive black cells followed by a single black cell, separated by at least one white cell. A question mark (?) represents a group of consecutive black cells whose size is unknown; an asterisk (*) represents any number of unknown groups of black cells, including none at all.

Monday Mutant 121: Tetra Firma (double)

In this Tetra Firma puzzle, every region contains two tetrominoes instead of one. The two tetrominoes in one region cannot share an edge. The rules are otherwise unchanged.

Inspired by the LMI test Puzzle Fusion.

There is now a Facebook page for A Cleverly-Titled Logic Puzzle Blog! If you want to promote my efforts to get Battle of LITS published, share this post. Including offline funding, I've raised about half of the money I need already! Help me get all the way there before December 26!

Monday Mutant 120: Polyominous / Tetra Firma

In this Polyominous puzzle, the rule that no two polyominoes of the same size may share an edge is specifically waived for tetrominoes, which must follow the rules of Tetra Firma (excluding the rule that every region contains a single tetromino). The number 4 never appears as a given in the grid; instead, the letters L, I, T, and S are given, corresponding to the shape of the tetromino.

I thought I clicked tomorrow's date. . . bah. You get this puzzle early.

In the past, I have plugged my board game Battle of LITS, which uses the LITS rules to create an original two-player game. Battle of LITS is now available on nestorbooster! 500 euros in pre-orders within the next month will allow Battle of LITS to become the next nestorgames publication! Without your pre-orders, though, this dream of mine will not happen. I hope you choose to help me get published with a meager 21 euro investment (which will be refunded if the funding fails). :)

Monday Mutant 119: Polyominous / Tetra Firma

In this Polyominous puzzle, the rule that no two polyominoes of the same size may share an edge is specifically waived for tetrominoes, which must follow the rules of Tetra Firma (excluding the rule that every region contains a single tetromino). The number 4 never appears as a given in the grid; instead, the letters L, I, T, and S are given, corresponding to the shape of the tetromino.

In the past, I have plugged my board game Battle of LITS, which uses the LITS rules to create an original two-player game. Battle of LITS will soon appear on nestorbooster, giving readers the chance to pre-order and fund the creation and sale of a portable version! Stay tuned!

Fillomino-Fillia 2 Preview Series: Skyscraper Fillomino

This is a skyscraper Fillomino (AKA Polyominous). The numbers in the grid should be treated as building heights. Numbers on the outside of the grid tell how many buildings are visible when looking from that direction. A building obscures all buildings behind it whose height is equal to or smaller than itself.

Answer Entry: Enter the units digits (last digit) of the number in each circled cell starting with the leftmost column and going right.

Highlight to see the answer: 64816117

Fillomino-Fillia 2 Preview Series: Walls Fillomino

This is a walls Fillomino (AKA Polyominous). A pair of cells with a thick border between them must contain different numbers.

Answer Entry: Enter the units digits (last digit) of the number in each circled cell starting with the leftmost column and going right.
Highlight to see the answer: 15321848

Fillomino-Fillia 2 Preview Series: Sum Fillomino

This is a sum Fillomino (AKA Polyominous). The grid contains some cages. The number at the top left of each cage gives the sum of all numbers that appear inside of it. Numbers may be repeated in cages.

Answer Entry: Enter the units digits (last digit) of the number in each circled cell starting with the leftmost column and going right.
Highlight to see the answer: 33751242

This variant will be featured on a "Best of Fillomino-Fillia 1" page, alongside a Cipher Fillomino.

Monday Mutant 118: Cross the Streams / Tetra Firma

Monday Mutant 117: The Inner Limits (multiplicative)

In this The Inner Limits puzzle, a number indicates the product of two quantities: the number of cells in an uninterrupted horizontal line from that cell (up to the nearest edges of the loop, and including the cell itself), and the number of cells in an uninterrupted vertical line from that cell (up to the nearest edges of the loop, and including the cell itself). The rules are otherwise unchanged.

Thomas Snyder posted a beautiful puzzle in preparation for the recent United States Puzzle Competition. It is my hope that I have made a puzzle at least as excellent as his.
 

Monday Mutant 116: Seek and Spell / Crowd Nine

In this Seek and Spell puzzle, every row, every column, and every outlined box consisting of nine cells each must contain every letter in FLINCH MAG exactly once (as in a Crowd Nine puzzle, but with letters). The rules are otherwise unchanged.

This puzzle honors Minfang Lin from China, the winner of my recent BoardGameGeek contest giving away cards from the World of Warcraft Trading Card Game, plus a custom puzzle for the winner. Even though Minfang Lin chose not to accept the cards, the other half of the prize remains.

Monday Mutant 115: Streaming Content / Tetra Firma

Shade in tetrominoes in simultaneous accordance with the rules of Streaming Content and the rules of Tetra Firma. (As the grid isn't partitioned into regions, the rule of Tetra Firma that every region contains one tetromino is waived.)

Monday Mutant 114: Room and Reason (wacky)

In this Room and Reason puzzle, not all of the rooms are rectangular. The white cells may not pass over two or more boundaries between consecutive rooms in an uninterrupted horizontal or vertical line (even if this entails exiting a room and then entering it again -- this is more specific than the usual rule which states that the white cells may not exceed two consecutive rooms in an uninterrupted horizontal or vertical line). The rules are otherwise unchanged.

Barry Figgins apparently makes board game accessories and the like out of wood. He is using Kickstarter to raise the money to upgrade his equipment. Thanks in part to some money given to me by a guy named Jay, I've been able to muster a $150 pledge, meaning that Barry will make me a wooden version of my board game Battle of LITS, one whose pieces don't get blown around underneath a ceiling fan! Thanks, Jay! And thanks in advance to Barry!
