Puzzle 351: Circumnavi-Gates 6
I've had to do some fiddling with the phrasing of the rules of this puzzle; more details can be found in a comment I've made on this post. 
Puzzle 350: Streaming Content 27
Christmas day -- an appropriate day to post puzzle 350, don't you think? I think it makes a very good Christmas present. I don't get any presents myself today -- inclement weather is preventing the rest of my family from coming to Dallas to see my mother and me here. As a result, I won't be able to open any presents until tomorrow. I feel slightly depressed. Opening a package of Nikoli puzzle books is what Christmas is all about! :( Hopefully, though, any fellow Christmas celebrants reading this blog will have gotten some very good presents. And tomorrow, I will hopefully be very, very, very excited. :)

Puzzle 348: Circumnavi-Gates 5
I have a most exciting announcement to make. Ahem.
This blog now has a custom favicon!!!
That had absolutely nothing to do with this puzzle, but I felt that it was imperative to announce it nonetheless.

Rules -- Circumnavi-Gates
Circumnavi-Gates was invented by the Japanese puzzle company Nikoli (under the name Suraromu).
1. Draw a single loop, starting and ending at the numbered circle. The loop may only travel horizontally or vertically, and never diagonally (so all turns are of 90 degrees). The loop may only turn at the centers of the grid cells. The loop may not cross itself or branch off. In other words, the interior of the loop will be a single polygon.
2. The dotted lines are called gates. The loop must pass straight through every gate exactly once, by traversing exactly one cell in each gate. (The number in the circle represents the total number of gates, and is included as a convenience.)
3. A numbered black cell represents the order in which the loop passes through the gate which touches that black cell. (If a numbered black cell is next to more than one gate, then the number refers only to the gate which has that same number on both ends.) A gate numbered 1 must be the first gate visited in the loop, starting from the circle and going in one of the two possible directions, a gate numbered 2 must be the second gate visited, and so forth. The other gates may be passed through in any order.

I've gone from not posting for a week to throwing together six puzzles in one day! Insane.
Rules -- Prev-Arrow-Cation
Prev-Arrow-Cation was invented by the Japanese puzzle company Nikoli (under the name Yajisan-Kazusan).
1. Determine whether each cell is white or black according to the following rules.
2. A white cell containing a number and an arrow represents how many black cells are in the row or column pointed at by the arrow.
3. A cell containing a number and an arrow may be shaded in; if so, the clue in it becomes meaningless, and may or may not be true.
4. No two black cells may share an edge. All of the white cells must be connected to each other through their edges.
