I really enjoyed the test. However despite knowing the trick of 8x8 star battle, I wanted to solve it logically and till now I am not able to solve it. It will be great if someone who solved it logically can post the steps to solve it.

Hi guys. What is the 8x8 Star Battle trick. :)

There are exactly two possible solutions for an 8x8 star battle. One is in the IB. To figure out the other you just need to reflect the configuration.

Yes.Adding to what prasanna said and to make things more clear , this is the scenario regardless of whatever shape the irregular region may take and which means that if you know for sure that one is not the configuration then the other is the solution ! for an 8X8 SB. Incidentally,I got to know about this just before the start of the test.

I am trying to start the test last 25 mins but looks like I am not able to. Any reason

The contest ended around an hour back.

The first episode of the inaugural season is over. Congratulations to Prasanna, Swaroop and Amit for taking the top 3 spots. They were the only three from India to complete the set. Anurag, Rajesh and Zalak took the next three spots.

Amongst the international participants, Congratulations to Endo for the top spot and Ulrich and Hideaki for second and third positions. They were way ahead of other participants.

Hitori Blocks (not surprisingly) and Star Battle 1 (surprisingly) had the least submissions. Four Winds (1 and 3) had less than 80% correct answers. This could have a correlation with the answer key as mentioned by some participants. Numberlink 1 also had 67% correct submissions. This could be due to the puzzle being the first one and most participants would have attempted this puzzle.

Thank you everyone for participating, and hope to see you soon in the next episode (Numbers) by Deb.

New players : If there is any specific Puzzle in which you got stuck, feel free to post here and we will guide you through.

I could not solve Star Battle 1 logically. It will be great if someone could post logically steps to solve it.

I am new. to this puzzles. Can the answers be seen?

Hi. Generally the solutions will be appended to the puzzle booklet in a day or two. Do follow this thread for the update.

I imagine that there is a better path than what I did (which had a lot of trial and error), but since no one else has responded yet, I will post my steps. If you have a question about any of the steps just ask, since I recognize that I am not including the full explanation for every step.

First, E7 cannot be a star since the bottom right region would not have space for two stars. Next, at least one of the stars in that bottom right region must be in row 8, since otherwise they would have to be in E6 and G7, and there would not be enough room for two stars in columns F and G. Thus, B6 cannot be a star, and thus B4 and D6 cannot be either, so D4 cannot be. Next, if E4 and G5 both had stars C2 would have to as well, so there would not be space for two stars in column B. Thus A2, B2, D2, and A3 cannot be stars. The two stars in row 1 are thus in the top left region, so G1 and H1 cannot be stars, and H3 cannot be a star either. Thus G5 and G7 cannot be stars, so E5 cannot be either. A6 also cannot be a star, so neither can D7 or B7. A7 thus has to be a star. A1 or B1 must be a star, so C2 cannot be one. Thus E1, F1, E3, F3, G3, C4, F5, H5, and C6 cannot be stars. Thus C7 and E8 are stars. If D3 and D5 were both stars there would not be space in column E, so D1 must be a star. Thus F2, H2, and D3 must be stars. The rest should be pretty straightforward.

By the way, is this test going to be included in the puzzle ratings? And is there a reason why feedback was not enabled for the test?

Ratings recomputed.

About Feedback page : I had planned to make few changes to feedback page, but couldn't finish in time. No other reason.

I hope for some other better solving path for Star battle 1. Can Mr. Rohan guide us.
