2. Every number must be contained inside the loop.
3. A number indicates how many grid cells, including the cell itself, lie in an uninterrupted horizontal or vertical line from that cell, up to the nearest edges of the loop.
Rules -- The Inner Limits
The Inner Limits was invented by the Japanese puzzle company Nikoli (under the name Bag, although the name Corral is probably more well-known amongst the global puzzle community).
1. Draw a single loop along the grid lines. The loop may not cross itself or branch off. In other words, the interior of the loop will be a single polygon.
2. Every number must be contained inside the loop.
3. A number indicates how many grid cells, including the cell itself, lie in an uninterrupted horizontal or vertical line from that cell, up to the nearest edges of the loop.

Monday Mutant 28: Process of Illumination (EX)
In this Process of Illumination puzzle, a number in a circle represents how many light bulbs are on cells which share an edge with that cell, while a number in a square represents how many of the edges of that black cell are illuminated by light bulbs (the top and bottom edges can only be illuminated vertically, and the left and right edges and only be illuminated horizontally). Some of the black cells are triangular; like other black cells, they cannot have a bulb on them, and they don't need to be illuminated. However, these cells function as mirrors, and reflect the light of any light bulbs which illuminate them. The rules are otherwise unchanged.

Monday Mutant 27: Fencing Match (crosslink)
In this Fencing Match puzzle, the loop may pass through a dot twice, but only if the loop goes straight through that dot both times, once horizontally and once vertically. The rules are otherwise unchanged.
Puzzle 420: Totally Awesum 21
Today is the 25th birthday of Mike Sylvia, a member of the puzzle community whom I've come to kinda sorta respect. He, and I quote, "may be the only person who can truthfully say his Facebook picture is of him drinking Dr. [sic] Pepper out of a wine glass in a Taco Bell while wearing a suit." What will he get for his birthday? A puzzle with two 25's in the first column! Yay!
Monday Mutant 26: Melon's Secret Castle
Draw a single loop that connects the grid cells. The loop may only travel horizontally or vertically, and never diagonally (so all turns are of 90 degrees). The loop may only turn at the centers of grid cells, and may not cross itself or branch off. A cell containing a number and an arrow represents the total length of the horizontal (for a left or right arrow) or the vertical (for an up or down arrow) line segments in the row or column pointed at by the arrow (or, equivalently, how many cell boundaries the loop passes through in that direction). The loop may not pass through a cell containing a numbered arrow clue, but all such clues which are in a white cell must be inside the loop, and all black cells must be outside the loop.

Puzzle 419: Eliza Pseudonym of Puzzlania 12
No comment.
During the month of June, Eliza Pseudonym and her friends Anna, Barbra, Carla, and Delilah each went to a venue known as The Euterpean Theatre to watch a different musical. Each woman went to the theatre on a different day (June 1, June 8, June 15, June 22, and June 29), and each woman paid a different amount for her ticket ($60, $80, $100, $120, $140). From the clues below, determine which musical each woman saw, which day each woman saw it, and how much each woman's ticket cost.
1. One woman saw "Rant" precisely one week after Anna watched a musical, but precisely one week before someone viewed "Pesticide Story".
2. Delilah's trip to the theatre was sometime before that of the woman who paid $100 for her ticket.
3. Carla paid $120 for her ticket; she went to The Euterpean Theatre precisely one week after the performance of "A Coarse Line" was attended.
4. Eliza visited the theatre precisely one week after the woman did whose ticket had a price of $80.
5. The ticket to see the musical "The Bantam of the Opera" was precisely $20 less expensive than the "Cots" ticket; one of these two musicals was the one watched on June 15.
6. Barbra bought the least expensive ticket.

Puzzle 417: Room and Reason 29
Issue 8 of Dr. Gareth Moore's Sudoku Xtra magazine contains two puzzles contributed by me! They are exclusive to the magazine, and will remain that way unless I figure out how to publish a book or something, so you may want to buy it. (The magazine also contains over 100 puzzles created by Dr. Moore himself, and a few pages of "Community Puzzles" contributed by others.) If you do buy the magazine, please consider sending me a small donation via PayPal, since the only payment Dr. Moore is able to give me is a free copy of the magazine (and the knowledge that my puzzles are being enjoyed). :)
Monday Mutant 24: Straight and Arrow (indirect)
In this Straight and Arrow puzzle, a number followed by a question mark represents how many black cells are in at least one of the four orthogonal directions (that is, the question mark can be replaced by an up arrow, a down arrow, a left arrow, or a right arrow, and be a normal Straight and Arrow clue). A number followed by an x means that none of the four orthogonal directions contain that many black cells. A number followed by a plus sign represents the total number of black cells in all four orthogonal directions. The rules are otherwise unchanged.
I plagiarized -- I mean stole -- I mean borrowed this mutant idea from MellowMelon.
ERRATUM: Sheesh, at this rate, my blog will have more errata than MellowMelon's blog and The Griddle combined by the end of the year! Due to my brain not working 100% properly, this puzzle had multiple solutions. . . until now.

Monday Mutant 23: Room and Reason (symmetry)
In this Room and Reason puzzle, a room with an S in it must have 180-degree rotational symmetry, and a room with an A in it must NOT have 180-degree rotational symmetry. The rules are otherwise unchanged.
Remember kids: the letter S stands for "symmetry" and has 180-degree rotational symmetry, and the letter A stands for "asymmetry" and doesn't have 180-degree rotational symmetry.

Monday Mutant 22: Battleships (Shinro)
Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown, but may not overlap or occupy cells which share a corner or an edge. A number to the right of a row or below a column indicates how many cells in that row or column are occupied by ships. No cell containing an arrow may contain part of a ship, but every arrow must point to at least one ship segment in that row, column, or diagonal (although not every ship segment needs to have an arrow pointing to it). Locate the ships.
This variant is inspired by a puzzle called Shinro, a puzzle apparently of Japanese origins.

Expect to see a good number of these as long as I have the book Heyawake Maru unfinished; solving the puzzles contained therein has definitely inspired me to create more of my own. :)
Puzzle 413: Polyominous 41
Today, I made some "apple pi" by freezing apple juice in a pi-shaped ice cube tray. It's surprisingly tasty, and undeniably geeky. It lets me pretend to be smart!
Monday Mutant 21: Polyominous / Battleships
Ten ships (as indicated below the grid: one four-cell ship, two three-cell ships, three two-cell ships, and four one-cell ships) are hidden in the grid. The ships may be rotated from the orientations shown (without changing the numbers), but may not overlap or occupy cells which share a corner or an edge. A number to the right of a row or below a column indicates how many cells in that row or column are occupied by ships. The numbers on these ships also function as clues in a Polyominous puzzle. None of the numbers already present in the grid are part of the ships. Locate the ships and solve the Polyominous puzzle.
