Genre Spotlight 38: Touch Match (Puzzles 334 and 335)

For today's genre, we're back on the Inaba train!  The type in question is Touch Match.  I came across this type earlier and wanted to write a spotlight for it, but one of the puzzles written for the blog became more difficult than anticipated, so it appeared on the 2025 USPC instead.  Many of Inaba's genres use "blocks" rather than "regions", and this is no exception.

Rules: Place triominoes (connected three-cell regions) along the gridlines so that they do not overlap and each contains exactly one of the given circled numbers. For each triomino, the number of neighboring triominoes that share an edge is equal to the contained number. 

            

Genre Spotlight 37: Nemo (Puzzles 332 and 333)

Today's genre is Nemo.  I've seen this genre a few times, mainly in GAPP and from Bram de Laat, but searching for it on the internet is impossible.  If anyone has any information about this type's origins, please let me know!

Rules: Place a number from the range given outside the grid into some cells so that each row and column contains every number from that range with no repeats, and shade all of the remaining cells. Cells with arrows must contain a number that represents the distance to the first shaded cell appearing in the indicated direction.

Genre Spotlight 36: Build a Maze (Puzzles 330 and 331)

Continuing on our 24HPC trek, we have Build a Maze.  I've done a loop version of Nonograms before, but this type is slightly different.  Like Hurdle and Remaze, the use of walls rather than a line creates an interesting feel that isn't seen in many other puzzle genres.

Rules: Place some walls in the grid, creating a path from one gray circle to another which visits every cell exactly once.  Walls are horizontal or vertical lines along grid lines with their ends at grid nodes.  Numbers outside the grid show the lengths of all wall segments in the corresponding direction, in order from left to right or top to bottom.  Question marks denote borders of unknown nonzero length.

                   

Question marks were not in the original ruleset, but complete information about rows and columns of the grid sometimes felt too strong.  Asterisk clues from Cross the Streams would probably also fit nicely.
