Moon or Sun

For my 100th puzzle, I’ve made my first giant: a 36×20 Moon or Sun.  I’ve been working on this one incrementally over the last two months, so it’s a bit of a hodgepodge.  This is a fun type to work with, though it can be challenging to prevent uniqueness-forces from giving away the solve path.

Standard Moon or Sun Rules

Proximity Snake

This is an adaptation of various Snake types to a [3.4.6.4; 33.42] tiling.

Rules

Draw a snake through cells between the two given ends such that:

  1. The snake does not branch or cross itself.
  2. The snake does not touch itself on an edge.  If two cells that share an edge are part of the snake, the snake must be passing through that edge. The snake can touch itself on a vertex (“diagonally”).
  3. Numbers in certain cells indicate how many of the cells that share a vertex with the numbered cell are occupied by the snake.  The snake cannot pass through numbers.

Deltoidal Trihexagonal Tree

This type is an adaptation of Branch (ブランチャー) by Inaba Naoki to a Deltoidal Trihexagonal grid.

Rules

Draw segments to create a network such that:

  1. Every vertex • and node O is connected.
  2. Vertices must connect to exactly two path segments.  Every branch of the network must form a path from one node to another.
  3. Numbers indicate the sum of the lengths of every branch directly connected to that node, in segments.
  4. The network is acyclic – there are no loops.
