A 3-Star Star Battle

[@jonasgleim7612]

Thanks for solving, glad you enjoyed the puzzle! Apart from the numbers, the shape in the middle is supposed to resemble the clock hands. Also, I tried putting the same shape in all four corners to frame the clock, but had to tweak it a bit in the upper right to make it work ;)

[@Wouter10123]

I thought the middle symbol was a + sign, so I was thinking: 12 \ 9 + 3 \ 6. What could that mean? I was looking for an equation, or maybe a date.

[@FazalFariz]

I happened to notice all that somehow. Amazing construction.

[@JaggerG]

Yeah, shame about the corners. Basically spoiled there’s a star in that extra cell. I opted not to use it in my logic, though.

[@adipy8912]

Beautiful. The good old time where Simon is kind to himself

[@ericwallhagen3146]

3 star puzzle? More like a 5 star puzzle! Took me a long time, but had some wonderful logic in it. Loved it!

[@dudbike]

One thing that helped me immensely was realizing the cell 2,2 isn't one and this works for all 4 corners.

[@ricardorix73]

10:56 if you have at-least 2 stars in a '5 cells in a line', then you can eliminate the adjacent cells to the 2nd and 4th cell.

[@tonybates6551]

I adore these star battles and particularly appreciate watching you solve them. Would love to see more!

[@richardfarrer5616]

Fascinating puzzle, which I took far longer to solve than that. I can see it will become much quicker once I can recognise patterns, as Killer & Kakuro are with sums. One thing I did notice, however, is that, in the shapes in the corners, there must always be at least one star in the outside rows. You commented on that at the top of the grid, but you could have used it far earlier at the bottom of the grid to resolved a lot of the bottom two rows. Also, though you didn't need it, the shape at the top left, bottom left and bottom right can't have two stars in their middle rows, while the shape at the top right can. Once you excluded all stars from the rest of the second row you could immediately fill in the top right.

[@freddiehand6551]

That was tough! Broke the puzzle after 19 minutes on computer, then solved it again on paper, finishing with a time of 12:34. I find that with very large star battle puzzles, I often struggle to visualise deductions which I would see very quickly in a smaller puzzle. Another mistake I make is to place 4 stars in a region, especially if the region spans multiple columns/rows. Very nice theme and puzzle!

[@crysias]

These puzzles are gorgeous, thank you to the creator and cuddos to the solver !

[@glennmelven3414]

I saw the 2369 but failed to see that that other shape was a 1 so I completely missed the clock face. As the 1 and 2 would make for the 12.

[@nouration9685]

I saw the 1, but kept looking for 4, 5, 7 and 8, thinking it had all the numbers from 1 to 9 lol

[@NYsummertimeCHI]

Mr. Light Same here, thought the hands of the clock looked a bit like a four that had been partially obscured, so I was thinking maybe the numbers were layered on top of each other somehow. Then I tried to think of what pattern they were layered in and noticed 3,6,9 what's next? 12. Oh 12, I see it's a clock!

[@littleschnitzel8226]

Wow, wonderful colorful puzzle! You really should make another app about these star puzzles.

[@danpowell806]

As soon as you rule out all of row 2 except the two corners, you can reason that there cannot be two stars in the top left shape in row two, so there must be two in the top right in row two, which fills in the top right shape.

[@florianzellmer8735]

Nicely done, jonas! As always a very beautiful puzzle with a brilliant solution

[@henrihell]

The bottom row could've been solved much earlier, leading to what I felt was a simpler way to solve it. It changed the bottom left box to having one star in each row instead of the two squares and a 3x1 line. There were also plenty of times where you needed 2 stars or more in a 3x3, which always eliminates the middle one. I believe this applied to all corners and the 9 at the end.

[@autodisplay2831]

Great puzzle. Very satisfying to solve.

[@sunriselg]

I needed some inspiration from you at the beginning and I had to trial-and-error the last part (23:00 onwards in the video).

[@kurzackd]

Incredibly, Simon left the most evident clues for last... namely that the central 2 cells of the NW, SW and SE corner shapes **CAN'T** be stars; as placing a star in either of these 2 central cells would deplete the available locations for the 2 remaining stars in the shape. He missed that obvious clue for the entire duration of the solution! O_o

[@binilgn5941]

Is it not just one of the cells that can be ruled out in each shape? If for instance you place a star in r2c3, you can still have stars in r1c1 and r3c1

[@palfly1864]

11:20 it wasn't completely wrong. You couldn't put a star in the top and bottom cell of the 3 you marked. Just the middle one was wrong

[@DaveGeelen88]

I love the variations ! :D So many Sudoku variations, so lovely xD

[@tommyisrael]

i just put a small 1 in the blue spots in the 2 to label it

[@srwapo]

Took me about 45 minutes. I spent about half an hour last night and it was reset this morning, so I redid it from scratch.

[@Elifre]

I worked on this for an hour and a half, and it ended up failing at the last minute with four stars on the bottom row, and two on the second from the bottom. No idea where I went wrong with that. :/ Really tough puzzle, but a lot of fun along the way.

[@nemoyatpeace]

I did the exact same thing!

[@Technomancr]

When I find out I made a mistake, I watch the video until I figure out where his solution differs from mine. Then I undo to that point, and try to figure out where my logic went wrong.

[@Bifonacci]

Really enjoyed this one!

[@fingerling1231]

This took me 41 minutes to solve. The 3rd star and larger grid made it a lot tougher for me. Still an enjoyable solve

[@mikes_.5_cent]

Do the Star Battle puzzles have unique solutions like sudoku ?

[@davidbeaumier4953]

After 2h, i failled miserably... first try and i'll have to work more on this kind of puzzle.

[@davidbeaumier4953]

and 40 more minutes leaded to another failure.

[@aboorsa]

you missed the clock hands in the middle

[@professortrog7742]

Nice puzzle, but calling it a star battle somehow sounds wrong to me. It is more a star field then a battle. Has a mush nicer ring to it in my opinion. Also the stars should be yellow and the voids should be dark blue.

[@pianojorge]

I solved this puzzle in 1 hour... Not a good time, but I’m really proud I solved it, 😂

[@nicokuhne3255]

the fact that stars arent yellow and non stars arent blue is giving me more anxiety than it should.

[@Max_Power_]

I mark stars with blue and non stars with grey.

[@gizel4376]

​@@Max_Power_ whatever the star color i feel like grey should always be the bad one, anyway the blue and yellow aren't good looking color on this app.i always try to use: purple, grey, green, orange and red. unless i have cross-mark to do:then i used blue for one, yellow for the other and green for both.

[@DNXTMaster]

you all would definitely love my black stars and red non-stars, haha

[@57thorns]

I have solved several of these at krazydad.com, I find them really challenging.

[@boskayer]

First !
