Round 6 had puzzles that were all combinations of different types of puzzles. There were some interesting ideas, but I doubt many of these will be seen more often again in future puzzle sets.
There's a few puzzles in here that I'm pretty happy with. The Starwacky puzzle is a nice solve. Snail on Snake worked out pretty well because it didn't need any extra given numbers, except for the head and tail. Galaxies and Tetrominoes is my favourite in the set, because it really forces the two types to work together.
The other puzzles should also be nice to solve.

Puzzle #179: LITS
This is the seventh practise puzzle for this year's UKPA Open.
If I've written more of the same puzzle type, I always find it hard to think of an opening. Usually in LITS I end up just putting down a few nice looking rooms and see if there's any interaction that I like. This combination of the letter LITS seemed to work for well. The end result worked pretty well, although it took a while to get it unique.
Rules for LITS

14th 24 Hour Puzzle Championship
This year I wrote a set of puzzles together with Hns Eendebak. I was a bit tight on time with a holiday and other championships that I wasn't sure if I'd be able to write everything in time. I still ran a bit late getting everything together but it was in time for the championship.
This year's championship was won by Peter Hudak. Nikola Zivanovic and Zoltan Horvath finished second and third.
There were 30 competitors total in this year's championship, of which 29 did our set. The set was a bit on the long side this year with the Michael Mosshammer from Austria being the top scorer with 695 points. It would have been better if the top scorer had about 100-150 points more. The set contained 24 puzzles in total, so I should have probably cut 2 puzzles in the end.
In this post I will be adding all the puzzles I wrote. You can find the complete set and all other sets here. If you need to see the instruction booklets for any of the set you can find them in this forum post.

Puzzle Competitions: ZeKa 2014
Last weekend was the ZeKa competition in Croatia. It featured both a individual and a team competition this year. The individual competition was won by Goran Vodopija; Marko Obradović and Dragan Tolomanoski finished second and third respectively . The team competition was won by Dragan Tolomanoski, Bojana Vojnović and Vanja Fornazar.
I provided one of the Team rounds this time. The theme of the round was Imposters. The round consisted of four classic puzzle types. Each type had 4 puzzles, where one of the puzzles was an Imposter. It wasn't actually solvable as that puzzle type, but was solvable under a different set of rules. The rules of this puzzle was provided. The imposters weren't designed to be logically deduced, but purely intended to break down under the original rules.
The four puzzle types were LITS, with Double Back as imposter; Shikaku, with Corral as imposter; Skyscrapers with Haido as imposter; Slitherlink, with Turning Fences as imposter. Two of these combinations have appeared on my blog as a Double Trouble puzzle. One of them appeared as such on Grant Fikes' blog. The other is probably possible as a Double Trouble puzzle, but haven't tried that yet.
Puzzles can be found below or in the following PDF.

Puzzle #112: LITS; Inversed
Today's puzzle is a variant on the LITS genre. I don't remember seeing it before. Constructing it went smoothly, although there were some points at the end where it caused trouble to keep it unique. Hope you all like it.
Rules for LITS
Colour some squares to form a single contiguous wall. The wall has no 2x2 coloured areas anywhere. In each blackbordered region a shape of 4 orthogonally connected squares remains empty. Identical shapes in different regions can't touch eachother by a side. Rotations and reflections are considered the same shape.

Puzzle #105: Quattro Stagioni (Corral, Nurikabe, Tapa LITS)
I have made a bunch of puzzles for friends for various reasons. Mostly for special occasions. I usually try to theme them in a certain way. This is mostly just based on the way the givens are oriented. For this puzzle though I had the fortune to get three handy numbers to work with, namely 2, 3 and 7. The numbers were handy to build into most genres, so I attempted to use them as best as I could. This puzzle is built up of four quadrants that each belong to a different genre. I thought a while about a good fourth genre to add as Nurikabe, Tapa and LITS have a similar general puzzle idea behind it. I couldn't come up with a good fourth genre that used this type of clue. So I cheated a bit by using corral-like clues, within the same puzzle structure. I think the puzzle worked out well, not overly difficult but still interesting.
General Rule:
Colour some cells to form a single contiguous shape. The shape doesn't form any 2x2 squares anywhere.
Left Top: "Corral"
The numbers in this section are all part of the shape. The numbers indicate how many cells that are part of this shape can be seen from this shape in horizontal and vertical direction, not including the cell itself. The numbers can't see past white cells. [Note: This section doesn't work like normal Corral. The clue type doesn't include the cell itself. Also there's no loop constraint.]
Right Top: Nurikabe
The numbers in this section each indicate a seperate island of orthogonally connected white cells. The numbers indicate the size of the island they are part of. All remaining cells in this section not part of an island belong to the shape. The islands can cross the border of this section.
Left Bottom: Tapa
The numbers in this section indicate how many consecutive cells are to be coloured around it. If there is more than one number in a cell, then each section of consecutive cells must be seperated by at least one empty cell.
Right Bottom: LITS
In this section colour 4 orthogonally connected cells in every boldbordered region. Two identical shapes in different regions can't touch eachother by a side. Rotations and reflections are considered the same shape.

Puzzle #98: LITS; Cube
I know I'm a day late. Yesterday was Valentine's Day. This puzzle I made for my girlfriend, who luckily thinks me being able to make puzzles is awesome. So every year I make a special puzzle for Valentine's day. This year I made a LITS puzzle on cube. I build the cube out of cardboard as you can see in the picture.
The puzzle for you is an unconstructed cube, which you can fold. The red lines are to fold, but otherwise mean nothing special.
Rules for LITS
This puzzle is on a cube, running over all 6 sides. Normal rules of LITS apply. No corner of the cube can be fully coloured. The pink areas are only for aestetics.
[Edit 19/02/12: Fixed small uniqueness issue in left face]

Rules: LITS
This genre was developed by Nikoli.
Colour a shape of 4 orthogonally connected squares in each black bordered region so that all coloured squares form a single contiguous area. This area can't contain any 2x2 coloured squares. Two identical shapes in different regions can't touch eachother by a side. Rotations and reflections are considered the same shape.
