ok think in this way to which galaxy does c14r2 cell can join, you will find only one way.

Personally, in a forty-minute contest, I think that good notation is going to make a huge difference. Every time I try a puzzle like this, I go back and forth between drawing the border and connecting the cells directly, wasting a lot of time and creating a real mess of lines across the puzzle. This may be one puzzle type where I need to break into my child's supply of color pencils...

Beginners' contest is delayed - we will post a note when it starts.

When is this contest actually starting, since I am not seeing anything other than the instructions booklet.

Quite unusually, we have run into some issues here. I can't put an exact time right now, but it will take around 12 hours, as I post this.

Great puzzles, Serkan! I really enjoyed solving them. But from my view, discovering the twisted rules is too difficult, I am not sure, whether beginners will get through it. I solved Galaxies about 20 minutes and 8-10 minutes was just about guessing the proper rules.

Great puzzles indeed. The puzzles feel reasonable (also I now know I'm not particularly good in Galaxies). I feel the exploratory rules for Galaxies is a bit stretching it though. Black and white circles are good ideas, but gray circles just sound like throwing the symmetry part of Galaxies away. I have no particular comments, although I feel Tetromino should also have a puzzle or two without givens.

Also, for some reason I blazed through the first six Tetromino puzzles in 11 minutes (plus two stupid mistakes on the first puzzle), and the last two in 17 minutes.

Excellent job, Serkan. I particularly enjoyed SG # 6, which I thought was quite clever. Thanks for the contest!

Great puzzles!

However, I think I have an indication if my answer is right or wrong before I really submit it. Is this indicated? (The red border of the cell vanishes if my answer has the correct length of the entry string before I hit the button.)

The red border vanishes when the sum of digits that you enter is equal to the size the grid (excluding black cells in Tetrominoes). It does not check for correctness of the answer.

For example, in Spiral Galaxy 1 - which is a 6X6 puzzle, if you enter 123 or 321 or 1122 or any set of digits summing to 6 the red border will vanish. We use this to check and alert if the answer is not formatted properly. Additionally, there is no penalty on answers which are not formatted correctly.

Hope that clarifies.

Oh sorry. I didnt recognize you can use the sum of the digits as a check.

I recently reached the Seasoner level, but the test still says, "You have chosen to play as Beginner." Is there a way to change my level to Seasoner?

I agree with most other posters -- really great puzzles, but on Galaxies figuring out the white/grey/black rule and checking on the given example took forever. (I should probably just have tried to solve #7 with the rule I guessed instead of wasting time trying it out on the example, but I really didn't have faith that I had guessed right).

I guessed wrong on #7 in such a way that produced the right answer, and only realized that when I was trying to do #8......

Thanks serkan, really beautiful puzzles.
Especially SG 5 and 6, Exploratory of Tetrominoes.
But unfortunately a bad test for me in Spiral Galaxies, I did continuously mistakes in all of them and at the end was confused to figure out rules for exploratory part and time got over. :(
After struggling little and fixing the rules it just took a minute each to solve each puzzle. :)

Thanks Serkan for excellent puzzles.
I enjoyed both tests, I felt that Tetrominoes is easier than Spiral Galaxies.
I figured the rules for Spiral Galaxies exploratory part in just 1 min but due to stress I convinced myself that I got the rules wrong and slept :D

Regards,
Ravi

How do I give up? The last two spiral galaxy puzzles are impossible to me; I am baffled by the example and I would just like to find out the rules. But the clock never runs out. Is there any way to forfeit? Seems rather difficult for a "beginner" contest.

i don't think you can do that, just leave it like that and when test ends it will stop.
But i would like to suggest you that try thinking in different ways, i also got stuck there but once figure it out its very easy :)
Just fix some rules what you think from given example and then try to solve, if you are not feeling its unique then try to extend some rules. :)

I can't read the post because I can't solve the last two puzzles. I've been staring at the example quite some time at different sittings. I can't come up with any rule sets that would give unique solutions. Very frustrating. I guess I'll just wait.

In case anyone else has this problem--maintain your printer! In the experimental spiral galaxy puzzles, my black circles and grey circles were all sort of...greyish-black and indistinguishable. I use a cheap laser printer and the toner is running low. This made figuring out the rules impossible without explanation. Thank you Swaroop for the PM. I looked at the original pdf file and indeed, there are three different colors of circles not two. Time to go to the office supply store.
