Monday Mutant 36: Room and Reason (regular minus domino)

The leftmost grid is a Room and Reason puzzle. The middle grid is a "mutant" Room and Reason puzzle in which, instead of no two black cells being allowed to share an edge, every black cell must share an edge with EXACTLY ONE other black cell (the rules are otherwise unchanged). The given numbers in the two puzzles are in the same locations (although some are shown as blank squares rather than numbers), and when the givens in the latter puzzle are subtracted from the correspondingly located givens in the former puzzle, the resulting differences are the numbers shown in the rightmost grid. Solve both puzzles.

Monday Mutant 35: Room and Reason x Streaming Content

The leftmost grid is a Room and Reason puzzle. The middle grid is a Streaming Content puzzle. The given numbers in the two puzzles are in the same locations (although they are shown as blank squares rather than numbers), and when the givens in the former puzzle are multiplied by the correspondingly located givens in the latter puzzle, the resulting products are the numbers shown in the rightmost grid. Solve both puzzles.

Rules of Tatami For Now

Monday Mutant 34: 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.

Monday Mutant 33: 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.
It's tough thinking of things to do with these rules which Thomas Snyder and MellowMelon haven't already done.

Monday Mutant 32: 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.
If you're a fan of today's Monday Mutants, I've created a 25x25 Cross the Streams puzzle which might appear in issue 9 of Sudoku Xtra. Can't be too sure, though, since Dr. Gareth Moore seems to be a little late publishing issue 9 this month. (Edit August 3, 2010: Sudoku Xtra 9 is now out, and does indeed contain my 25x25 Cross the Streams puzzle, in addition to two other puzzles exclusive to the magazine.)

Monday Mutant 31: 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.
I'd always wondered how Griddlers/Hanjie/Nonograms/Paint by Numbers/Pic-a-Pix/Picross (that's a whole lot of freaking names -- and those are just the most well-known ones. . .) would work with wildcards. This was the result.
