This is a Hashiwokekaro puzzle. Here are the rules for Hashiwokekaro:
Draw zero, one, or two straight bridges between each pair of islands. Two bridges cannot cross, and bridges cannot cross through islands. The number on an island describes how many bridges are connected to that island. You must be able to get from any island to any other island through bridges.
This is a Friday corral puzzle, with the exception that cells with numbers are allowed to be inside or outside the loop. Note that cells outside the loop only see cells outside the loop, until blocked by the loop or the edge of the grid.
In case you didn’t like Wednesday’s In/Out which only contained the digit 2, I made this one so that 2’s the only digit that doesn’t appear!
This is a Thursday nurikabe puzzle, with the exception that cells with numbers are allowed to shaded or unshaded. Note that a shaded number states the size of the island it would be in if you were to unshade that cell. The question marks can represent any (positive) integer.
This is a Wednesday corral puzzle, with the exception that cells with numbers are allowed to be inside or outside the loop. Note that for cells outside the loop only see cells outside the loop, until blocked by the loop or the edge of the grid.
This is a Tuesday tapa puzzle, with the exception that cells with numbers are allowed to be shaded or unshaded. Note that a cell with a number will never count itself, only the eight cells around it.
This is a Monday loop puzzle, with the exception that cells with numbers are allowed to be shaded or unshaded. Note that a cell with a number will never count itself, only the eight cells around it.
An interesting variation that can apply to a whole bunch of types of puzzles. It might be harder than a normal Monday, but it’s the easiest puzzle this week, I think.
Fill in the following crossword, such that each box has a letter filled in it by its across clue which is either directly after or before the letter filled in it by its down clue in the alphabet. Note that A is considered to “wrap around” to Z. I’ve given the grid twice, for convenience.
Now I know that I already said that I wanted to push the boundaries of Knapp Daneben, but I really doubt anyone expected a crossword as even a possibility to appear in this theme! I’m not generally a great crossword constructor, but I’d think it would be interesting to see other crosswords with the Extra Grid or Toroidal variations, for example. (Maybe even Exactly One Letter somehow?!)
ACROSS
1.) One who does jack
6.) Church songs
7.) Chose
8.) Without fallacy
9.) Babble on
DOWN
1.) “_____ be square” (2 wds.)
2.) The parts of DNA which get converted into proteins
3.) Someone clumsy
4.) Extinct birds
5.) Mount for a lancer
This is a Thursday star battle, but instead of two stars, each region, row, and column must have either one or three stars.
This type is really finicky. I was surprised with how well the masyu and double back worked, and I think they definitely have potential to be revisited, but knapp daneben with star battle really doesn’t have much potential at all (well, excluding the potential to be an April Fools puzzle, where you must put one more or less than one star in each row, column or region.)
This is a Wednesday double back, except that, instead of visiting every room exactly twice, you must visit each room exactly once or exactly thrice.
