Tunnel Vision
Tunnel Vision = Wild Labyrinth + Corral Clues = Build A Maze + regular expressions + Corral Clues.
The longer version of the rules goes something like this. Find an open, 1-cell wide path of edge adjacent cells which visits all cells exactly once. This path is entirely forced by drawing walls on grid lines. A clue inside the grid indicates the number of orthogonally visible cells, including the cell itself. Visibility is obstructed by walls. Clues on the outside indicate the length of walls along the grid line in order of appearance. Consecutively clued wall segments may not overlap, nor share corners. A single wall length may be replaced by ?. Any number of clues, including none, may be replaced by *. An unclued line is equivalent to *. A line with no wall segments may be clued as 0.
To the best of my knowledge, Riad Khanmagomedov invented this puzzle type, and Grant Fikes added the regular expressions. The idea of inserting Corral-style clues inside comes from a previous post.

Fiddly Norinori
Rules. I started out trying to make a Norinori with a bit of a bite to it, and I think I bit off more than I'd like, as a solver, to chew.
Hitor misses
Yes, I know these Hitori puzzles (rules) break a design convention. Tricky if you haven't seen this sort of thing before.
Sun & Moon
Draw a loop visiting all cells exactly once, by joining adjacent cell centres with horizontal and vertical line segments. No corner is formed between two consecutive identical markings. Exactly one corner is formed between consecutive different markings. Turns on the markings themselves are ignored by the previous two rules.
Word Toy
4 toy cubes have one letter written on each side. The Greek words below can be formed using the 4 cubes. Partition the alphabet into cubes.
Test solve data suggested I underestimated solve time by a factor of 3. Consequently, I'd like to know the Internet's experience.
ΑΒΓΟ ΒΗΧΩ ΔΙΚΗ ΖΕΣΗ ΘΕΟΣ ΚΕΝΟ ΛΙΜΑ ΜΕΤΑ ΠΟΘΩ ΠΡΙΝ ΦΟΛΑ ΧΥΝΩ ΨΗΛΟ ΨΥΞΗ

Expired Rings
I have a stock of puzzles intended for a contest that didn't happen. This one is the most obviously dated:
Write all digits from 0 to 9 on every ring. Any given clue is the result of addition, subtraction, multiplication, or exact division between the numbers to the immediate left and immediate right of the cell the clue is close to.
This was the final puzzle of the test, since I like tests to end on a high note for puzzlers rather than authors, and easier puzzles make hitting that note easier. This was also the last to be written, since I realised I was rather light on arithmetic content. Thanks to fantom for pointing out a typo in the original version.

Greek Sudoku and Puzzle Championship writeup
This post ended up as a wall of text, so look under the fold at your own peril.
TL;DR version
I did much better at sudoku and much worse at puzzles than I anticipated. Puzzles were of modest difficulty but rather neat. Test format leaves a lot of room for improvement, including typesetting, problem type selection, and examination format. Still, fun overall.

Easy Heyawake
Rules - for this problem, the no three rooms rule degenerates into "white stretch may not contain two boundaries", as per link. Also, the pzv environment solution checker may not work properly, due to the non-orthogonal rooms.
Medium Nuribou
(Rules) This one is much easier than the previous, and it does have a bit more of the Nurikabe vibe.
Hard Nuribou
Nuribou (ぬりぼう) is another rare Nikoli type. The rules are:
Paint some empty cells black so that they form strips of width 1. These strips do not share sides. If they share corners, then they must be of different lengths. All remaining white regions contain exactly one clue. Clues give the area of the containing region.
This really shouldn't be your first Nuribou, so of course it's the blog's first.
EDIT 1/6/19 : It has been reported that a 2-long strip in the lower left quadrant may be placed in two ways. This does not effect the remainder of the solution.
