Seeing the name of the latter genre reminded me of the former, which inspired this doppel. Constructing it ended up being a puzzle in itself due to how Tile City tends to require lots of small regions somewhat near each other whereas Number City tends to need large regions near small ones. https://pzprxs.vercel.app/p?tilecity/6/6/3jvs9cui09dmzj https://pzprxs.vercel.app/p?numcity/6/6/zv3jvs9cui09dm

Back in February, I spent some time solving old puzzles on Puzzle Square JP. So far, I've only decided to skip four and am currently procrastinating on attempting a Habanero-level Sudoku. I was reintroduced to Nanro and found it to have lots of promise in its logic, but the region structure made it difficult for me to set. Nevertheless, I have set a couple worth sharing: (Made on 2/15/25) https://puzz.link/p?nanro/10/10/14285ga0k50a1k284g000s0700vv00s07000o2k3l-15zi2h43h3zi3l3k4o (Made on 2/16/25) https://puzz.link/p?nanro/4/4/94g1s0i21o3g https://pedros.works/paper-puzzle-player.html?W=4x4&L=(1)2(3)6(2)7&SIT=2RRRR8UUUU&G=speckled-bands

 Hidato seems a lot more approachable and controlled than knight's tours, but it can still get difficult with puzzles that require holistically planning connections and finding crossings. I'm not too familiar with this genre, so both puzzles I managed to set today are small and relatively easy. https://pedros.works/paper-puzzle-player?W=5x4&L=(12)3(20)4(2)3(4)6(16)3&G=hidoku https://pedros.works/paper-puzzle-player?W=5x5&L=(1)4(16)1(2)4(20)6(12)2(24)3(8)3&G=hidoku The megapuzzle for Christmas Day is going well and I expect it to be ready on time. I'll probably release it automatically at 9:00 AM in my timezone.

M aybe I had channeled my inner navigator. Looking behind me, I do have a hunch that I didn't walk over the southeast corner of this island, but apart from this, I've managed to be extremely thorough in travelling everywhere without retracing my steps. I plan to spend today drafting a map as the waves approach me from three sides. Rules:  Draw a path, which visits every cell but may move diagonally and cross itself, that starts by moving from the 9 to the 2 and ends by moving from the 1 to the 0.  Place a digit from 1 to 8 in each cell such that each digit stands for a different compass direction, which you can keep track of on the right. The path must travel one space in the corresponding direction from each number. Circles are Kropki clues: cells separated by a black circle have a ratio of 2:1 and cells separated by a white circle have a difference of 1. penpa link

 I was recently digging through some papers that were about a year old and rediscovered this puzzle idea. I'm pretty sure it was meant to be another take on the idea of Romantic Spot (see elsewhere in blog), but the ruleset ended up feeling a lot more cohesive and less arbitrary. The first two puzzles (one of which is solved for you as an example) were taken directly from the paper and the larger one was made on 8/5/24. Place a 0 or 1 in some cells so that all the digits are orthogonally connected and every horizontal/vertical run of digits forms a binary number that describes its length. It might not be obvious from just these puzzles, but this puzzle type does have the capability to get really explosive. For example, using proper placement, only three digits are needed to force a single solution in a 9x9 grid! And yet, somehow, this ruleset does have the means to slow down its expansion given enough space and care.

 I discovered this genre on Puzzle Square JP and found it to be a relatively smooth yet rewarding solve for a relatively obscure puzzle type. When the Dash Spider memes went viral, I decided to try my hand at a themed puzzle and considered this type to work well for it. https://puzz.link/p?makaro/10/8/vqjhunfutpvivjglntvjlbqvlvqvlhegcaickandaoakbiajaaiajaanaakbh

 A good example of a puzzle type that relies on numbers but feels like it might not need to - each number has different properties in the solution. I did end up learning a cool technique involving the parities of 2s and 3s, but I'm unsure if it's required in these puzzles. Sukoro is surprisingly fast at spreading sometimes and has trouble filling in gaps other times, leading to a sort of constrained sprawl that merits its alternate name. https://puzz.link/p?sukoro/7/4/b12a2a1l1a2a23b https://puzz.link/p?sukoro/7/7/b12d1b2a1d3k1d1a2g23b No 12x23 puzzle today, sorry. I've been hard at work on the Day 25 puzzles and I don't know if I'll be able to finish them on time.

 made on 4/30/22 This puzzle type and variant were invented by thejonymyster. Write a positive integer into each cell of the grid so that every row or column containing a number n must contain every positive integer below n (e.g. if a cell contains a 3, it must be on the same row as at least one 1 and one 2, and on the same column as at least one 1 and one 2). A number with an arrow in its cell must see exactly one copy of itself in that direction (e.g. if a cell contains a 2 and a downward arrow, there is exactly one 2 below it in that column, no more and no less). (See #159 for another numpoint.) Variant rules: Black arrows tell the truth while white arrows lie. Numbers separated by white dots are consecutive.
