Puzzle 85 (Akari)

Have a late-night Akari 🙂  Intended to replicate the types of puzzles found on the SmartNikoli app, since I've been solving quite a few of those the past six months.

Puzzle 84: "Ellipse" (Tapa (Line))

Have another Tapa (Line) puzzle!  These are notoriously difficult to construct for me.  I think my style, especially with lots of clues around the perimeter, is to resolve the outside and then have the line constraint push into the middle of the puzzle.  Unfortunately, more often than not, this results in puzzles that break with no prior warning.  The line constraint is just too powerful.  (Indeed, at first I only had the perimeter clues and/or a clue at the center of the ellipse.  I only managed to construct a successful puzzle when I placed extra clues at the foci instead.)

Standard Tapa rules apply.  Additionally, no four consecutive vertical or horizontal cells may be shaded.

Puzzle 83 (Nurikabe)

Here's a Nurikabe puzzle in the style of Bachelor Seal.  This was designed to "fill in" a gap in Bachelor's blog, where yesterday it seemed as if there were only two puzzles instead of three.  (The third one showed up later that day; there must have been a tech error, or something.)  Thus, while this doesn't have an aesthetic theme, it does emphasize the smoothness of the solve.

Puzzle 82 ("Surrounded", Kakuro (Double))

Time for a Kakuro variant!  First one on this blog, I believe.

Rules (cf. GMPuzzles): Variation of Kakuro. The gray (2×2) cells are to be filled by a single digit which sits in multiple rows and columns. No digits can repeat within an entry, regardless of if it is in a small or large cell.

I'd personally recommend printing or taking a screenshot of this one, since the interface for Double Kakuro isn't the best.  However, if you want to use Penpa, place the digits in the dashed circles when solving.
