Puzzle 6 / Colour Scrabble:
It seems every time I run an event I end up with something non-culture neutral. I took great care listing as many obvious items as I can. Worrying so much about how non-English speakers would find it, it was a relief (?) to receive these comments from solvers who’s English, I ignorantly assume, is their mother tongue.

[Nick says:] “I solved as if any word could be assigned any color”

[Alan confessed:] “I confess – I ignored the colours to solve, and only now see that the items in the list have a (RBY) colour associated with them!!”

[Tom noticed:] “The scrabble became a lot easier when I started taking into account the meanings of the words!”

Apparently, even if the words were meaningless to you, the puzzle itself was still solvable. Phew.

Puzzle 8 / Colour my World
Wait. Where’s Puzzle 7?
Irodoku has a long background. I will post more about that separately soon.

A brief note for puzzle 8 since, after all… “Puzzle 8 is just word search; what am I supposed to comment about a word search?”
Solver Ivan’s right, I’m not going to even make a solution image for this one. (Edit: 28/01/2014 – why not?I did my best to provide you with the best format I could strive for. I tried printing different shading, font size, gradient and so forth to see which presentation would work best on paper. I still feel it is not the best format and I apologize.

The idea of black and white items being in a word search is just too tempting to exclude. The black items (eg. BATMAN, GORILLA,  LONDON CAB) are in the black letters and the white items (eg. IGLOO, SUGAR, AMBULANCE) are in the white letters. Some items that are both black and white (eg. CHESS PIECES, CROSSWORD, SKUNK) will be somewhere in between. I The best medium to solve a word search that requires treasuring the leftover letters is to use a felt pen. The message reads:  “WHAT IS THE ACTUAL COLOUR OF A PLANE’S BLACK BOX?”

Despite its name, the black box is actually ORANGE.
An appropriate answer to end Colour Restore don’t you think?

Does anyone know why it is called ‘Black’ in the first place?

And that’s it for Colour Restore. I hope to see you all again in my next event!
Happy 2014!

Puzzle 4 / Colour Akari:

This is not my idea entirely. A similar puzzle appeared in Nikoli Communication 135 and I modified their rules. There are several differences.

Nikoli Communication 135

As you can see, Nikoli used chromatics mixing as solver Joshua pointed out:
As light bulbs should the bulbs be cyan, magenta, yellow instead? Maybe these are actually paint shooters or something!

Some solvers may have been put off, Jack says:
…part of me was enough of a science nerd to be mildly bothered by the conflict between “lightbulbs” and pigment mixing — I wanted red and green to make yellow and so forth.

Entirely my fault, I completely forgot about the real-life science behind light colours. In addition to that, Nikoli’s bulbs only apply locally whereas the bulbs in the puzzle you solved shine along the entire row and column. Also, on the first page, the Akari actually retain their normal clue numbers.

Which one do you prefer?

Puzzle 5 / Colour Tapa:
Now the next 3 colour puzzles are not rip-offs, in case you’re not impressed with me for copying. When I was listing puzzle types that had the potential to become a new variant when colour was added, Tapa was marked with several stars. I really wanted to do a Colour Tapa, but how would it play out?

I had several ideas before this. Maybe the numbers in the same clue cell would have different colours? Maybe the wall is coloured with no single-area restrictions? Maybe the white cells at the end of a Tapa be coloured somehow?

The ideas rolled around for a while and this was born. I think Colour Tapa is interesting and would like to see more of this from other authors. The break-in I put in was that the blue needed to travel all the way down from the “4” to the “7”. Conveniently, there is only one column that can cater that.

Puzzle 3 / Pentapamino
Last February I had to work in a rural hospital for half a month with no computer access. During breaks (or non-breaks, behind my boss), I scribbled puzzles in my diary. This puzzle was from one of those scribbles. Originally written for UKPA’s 2013 offline event in Birmingham, this Pentapamino went unused and this was the new outlet for it.

This is where I make my puzzles.

This is where I make my puzzles.

Solve like you would do with a normal Tapa. Once you get to this point:

Ivan Koswara noticed: “…was Puzzle 3 actually need to figure out the position of X midway through the solve?”
Exactly. Ask yourself, “Hmm. Where can the X-pentomino be?” Believe it or not, there’s only one possible location for the X piece!

pentapaans2Well done, that was the hard part.

Puzzle 1 / Heyawake:
A quick glance at the bottom should identify the 3×2 box (labeled ‘3’) as the break-in point. The puzzle solves clockwise from there. This is my first attempt at making Heyawake, I’m not really into Heyawake because of the restless shading involved, especially in the big ones. Since the first 3 puzzles are aimed at making you hate shading, Heyawake was probably a good choice.

Puzzle 2 / Seramik:
This puzzle type was invented by Serkan Yurekli, I first saw it in OAPC 2. Because of its size and constraint, I think Seramik are one-off puzzles. There is not much you can do with Seramik, where one clue affects the entire grid. Once you try to make it difficult, the solving path quickly involves a lot of guessing. As with other Seramik puzzles, keeping track of the all possible shapes is important to solve the puzzle.

This walkthrough will be applicable to Seramik in general so keep some of these ideas in mind if you’re going to encounter Seramiks in the future (since there’s just so many of them). You can’t enter the puzzle with a Hanjie-frame of mind. It may look like there are multiple possible locations for the 2s, but because they have to be nested away from the 1s, the 2s are usually forced.

The first idea is to look for repeats. Here, the yellow and green 2×2 boxes each have two possible outcomes. Either way, those arrangements will be used – so the four patterns cannot appear anywhere else. Another important question to ask is: ‘where can the box with all shaded cells be?’ Here, the circled box is the only possible place.

As noted, each of the orange boxes can take two possible arrangements. However in each box, one of two arrangements has already been reserved by the yellow boxes. We can now deduce the pattern of both orange boxes. By now, the remaining arrangements can be placed smoothly to complete the puzzle.
