I'm really confused--what is the "Cat bonus"? I have no idea why I didn't receive it for Tetrominoes...

Cat Bonus is short for Category Bonus which is explained in the Instruction Booklet. There's some bug in the score page, and you are eligible for the bonus. We will look into it and rectify it as soon as possible.

I would be grateful if you could see my "cat bonus" as well - solved all the tetrominos in time, so probably should get the full score for that? Best - Bartek

About Tetrominoes #5
I have these rows: K: LLTIIIIOO (alternatively TZZIIIIOO) L: ITTTIZZIL M: LLLTTTLL
Which seemed to have an answer of 2142 (or 1242) 131211 332
But neither answer was accepted. Tried a couple of times to see if I fat-fingered them.
Resolved MANY times but always came up with this answer.
Where have I gone wrong?

Your first and third answers are wrong. The rule says each tetromino may contain at most 1 letter. With the first 2 answers you gave me, I cannot satisfy the L in R4C4. Without seeing a photo of your solution, I cannot comment further, but the error is probably the entire left hand side, pretty much the whole first 4 columns.

As a general rule of thumb, if you got more than 1 solution, both of them are almost certainly wrong, and the error is usually not in the ambiguity itself, but somewhere further back that gets you to this ambiguity in the first place. (Unless of course the error is that you missed part of the rules.)

Fixed.

I'm unable to view my Tetrominoes submissions

The pdf files from Yin-Yang variations contest site are not accessible.
They can be downloaded from here and here. Thanks Andrey for sharing.

Hi!

BW02diogen

Thanks

In the first example of Yin Yang Variations Contest, there is another solution possible with the answer key as BBWWW, BWBBW.. Is this correct?

Yes i think. Even i am getting multiple solutions (as you mentioned)

Any pointers on how to go about solving the Count puzzle in Yin Yang Variations contest? I'm unable to get a start. The example given is too easy.

The key is Rohan's post:
http://rohanrao.blogspot.in/2010/12/solving-black-and-white-edge-co...

There is 5 black circles in the 1st row and 3 in the last.
So there are only 2 ways:

The full right side is black and the first 5 circles in 1st row and first 3 in last row.
OR
The full left side is black and the last 5 circles in 1st row and last 3 in last row.

The second one won't work if you try it, because of the 2 in 3rd column. It leads a contradiction in 2nd column.

When you fill the edge you can solve the puzzle. (For instance you can continue in 2nd row.)



In the second one it is also possible to fill the full edge. According to the given numbers on the edge and the number 1 in C5.

Thanks! That helped! It didn't strike me before. :)

Just a note about the answer key of Yin-Yang, although it is clear in the IB :

For each marked row, enter the number of black circles, including the given ones.

Yin-Yang last puzzle (exploratory) was simply awesome :)
Also Minesweeper 6th puzzle was awesome :)
Nice Contest. I requested for credit in Minesweeper don't know will get it or not. I thought the stretch of 3 cells is like 3 mines. so was submitting total cells and it gave wrong and then thought it is single dynamite. Apart from that a nice contest for beginners. :)
Thanks to Author and LMI. :)

Somehow I am missing the category bonus for the minesweeper, despite finishing everything within 20 minutes.

Anyways, I have a complaint on the formatting of the PDF. My printer is cutting off the top and bottom of each page. While it didn't actually cut off the puzzles, it cuts off part of the instructions and exploratory puzzle sample.

The puzzle types themselves are right up my alley, especially minesweeper.

Still struggling to figure out why some player have it, and some don't.

Noted. Will make the margins larger from the next set.

As I know we accept both format in 7th and 8th Minesweeper puzzle.
But you typed 646 instead of 656.

Can the puzzles be solved online?

So I blazed through the test and found out I've topped both scoreboards for the moment. I'm expecting these to be beaten when the Japanese players come in or something.

The puzzles are great. My first thought of the exploratory variant of the Minesweeper was Double Minesweeper, but apparently it's totally wrong, heh. I didn't even have any idea of what variant could go to Yin-Yang, and I found that. Very well done. My favorite would certainly be Yin-Yang 8th.

Also, I should have used red/green or something instead of red/light purple for Yin-Yang; I couldn't distinguish the light purple from the given exploratory gray that easily and had to spent precious seconds shading in the white areas too due to that. Oops. (Yeah, I'm Paint solver.) Definitely not a complain for the formatting of the test, more like my fault for not choosing the proper colors.
