Kotak-Kotak:

This is a new 3-d puzzle type based on an earlier type of mine called Dervish PackingThis puzzle consists of several square grids of the the same dimension that together make up a cube.  Future puzzles could be rectangular solids as well ( Read more... )

Dervish Hotel

Here's a somewhat larger puzzle of a type I came up with late last year. The original post (along with the rules and a walkthrough) is here.

I think this is my first repeat puzzle on this blog.  I got some nice feedback on this type last year so I hope you enjoy it.

Dervish Packing

This has elements of the Nikoli puzzles: Tentai Show, Fillimino, and the semi-obscure NIKOJI. The fun thing about this one for me is that I have finally moved beyond black-and-white into color.

Tentai Fillomino

This is another Tentai-inspired puzzle, this time based on Fillomino. You might want to check a previous post called Tentai Nurikabe. If you did, the explanation below will be eerily familiar :).

Because of the symmetry constraint, you'll find these are a bit sparser than  typical Fillimino puzzles.

Nurikabe Variation #2: Tentai Nurikabe

This is the 2nd post on Nurikabe variations. The first post is here.
Explanation

Tentai Nurikabe is a type of puzzle with an additional constraint that all the islands have two-fold rotational symmetry. This is a fancy way of saying if you rotate the shape 180 degrees (or halfway around), you end up with the ( Read more... )
