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.

Sorry about the lack of any sort of mutation at all in this puzzle. I promise that tomorrow's puzzle will be completely different.

March Mutant 19: Cross the Streams / Tetra Firma (arbitrarily 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. In a normal Cross the Streams, 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. However, in this puzzle, some of the clues are inverted, and refer to the groups of white cells in that row or column. (A clue may coincidentally function as both a normal clue and an inverted one simultaneously.)

When will the arbitrary madness end???
ERRATUM: The original version of this puzzle had no clue in column 5, and more than one solution. Happy Quantity-Not-Quality Month!

March Mutant 1: Cross the Streams (arbitrarily inverted)

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. In a normal Cross the Streams, 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. However, in this puzzle, some of the clues are inverted, and refer to the groups of white cells in that row or column. (A clue may coincidentally function as both a normal clue and an inverted one simultaneously.)

This is an extension of the idea presented in Monday Mutant 94. Now you don't know which clues are inverted and which are normal! Gwa ha ha!

I have 15 votes so far in Logicsmith Exhibition 5. The deadline is later this month, so be sure to vote if you haven't already!
In even more exciting news, I recently got 100% completion in the Super Mario Advance 2 remake of Super Mario World! This means not only getting all 96 exits and saving the Princess, but getting all of the Dragon Coins, as well!
