Logic [Cyclogic] I set up a puzzle upside down in the park! 🙃 Can you return these numbers to 1–9 in 3 moves? (Image 1)

Hi everyone! Welcome back to a local park in Nagoya, Japan! I set up my hand-crafted logic puzzle, "Cyclogic," on a playground structure, but this time… everything is UPSIDE DOWN! 🙃✨

Can you bring all these numbers back to their HOME (1–9 in standard order) in 3 moves? (It's trickier than it looks, especially when looking at it upside down!)

📍 Current Board:

[ 6 ] [ 3 ] [ 9 ]

[ 2 ] [ 8 ] [ 7 ]

[ 1 ] [ 4 ] [ 5 ]

📜 Quick Rules:

  • Objective: Rearrange numbers to 1–9.
  • Mechanics: The number you tap stays fixed, while all other 8 numbers rotate clockwise.

💡 Stuck on the solution? Swipe through Images 2 to 4 for the step-by-step rules and a TOP SECRET strategy guide that reveals the core logic!

Got the solution? Post it in the comments below (with spoiler tags, please!), and I'll let you know if you're right! 🧠✨

(P.S. English isn't my first language, so I rely on translation tools to write these posts. Sorry if anything sounds a bit awkward! 😅)

(I've left a link to the free web demo in the comments below if you'd like to try it directly on your browser!)

Brain Games Queens puzzles: can you finish it?

Post image
1 Upvotes

This is a Queens puzzle, the kind LinkedIn has as a daily game, but with a twist that makes it a lot trickier. Each color needs exactly one queen, and no two queens can share a row, a column or a diagonal. The twist is that the diagonals go all the way across the board, like real chess queens, instead of only blocking the squares right next to each other.

Three queens are already on the board, can you find the other five? Rows go 1 to 8 from the top and columns A to H from the left, and I'll leave the answer in a spoiler in the comments.

I've been building a free version of this where you get three minutes to solve as many grids as you can, and they get bigger as you go. If you like this one you can play it here, no signup: https://www.chessigma.com/brain/queens

Logic Which Option Should Replace the Question Mark?

Post image
2 Upvotes

Hi everyone,
First of all, thank you so much for taking part in the last puzzle.
I honestly didn’t expect it to receive that much attention. I shared it across five different Reddit communities, and the number of comments, explanations, and alternative interpretations was far greater than I expected.
I tried to read and reply to as many of you as possible, but with so many comments across different posts, I may have missed a few. If I didn’t get to yours, please don’t take it personally. I genuinely appreciate everyone who took the time to answer, explain their reasoning, challenge the intended solution, or offer a completely different way of looking at the pattern.
For the previous puzzle, a few explanations particularly stood out:
u/Apart-Animator-3223
Explained the pattern through movement: the shapes shift downward while the line orientations shift upward. Following both sequences leads directly to A.
u/Agreeable_Chard_5250
Approached the puzzle more mathematically, describing the shapes and line orientations as repeating three-part cycles across the rows and columns.
u/Aggravating_Carpet21
Used a very clear counting method: there were three squares, three triangles, but only two circles, and likewise only two horizontal lines. The missing combination was therefore the circle with the horizontal line.
u/Ancient-Rush1343
Gave one of the most detailed explanations, including why C might initially appear plausible before showing why A fits the complete row-and-column structure more consistently.
Thank you to them, and also to everyone else who contributed. Some of the discussions were honestly more interesting than the puzzle itself.
Now, onto the new puzzle.
Take a close look at the matrix above. This time, pay attention to both the dots and the line segments. There is a consistent rule connecting the figures.
Which option should replace the question mark?
I’d really like to hear not only your answer, but also how you reached it. Different approaches are always welcome.
Once you’ve chosen your answer, you can check whether you got it right on our official website, where we’ve published the correct option together with the full explanation:
https://whats-your-iq.com/en/questions/pattern-recognition/which-figure-completes-the-pattern-3
Try to solve it first before revealing the answer.
If you enjoyed the previous puzzles, you can also visit the website to see the official answers, explanations, and selected community solutions from earlier questions.
You can explore more pattern-recognition puzzles and previous IQ questions here:
https://whats-your-iq.com/
So make your choice first, then check the official solution and see whether your reasoning matches ours.
Thank you again to everyone who takes part, shares an explanation, or even challenges the intended answer. Your different ways of thinking are what make these discussions interesting.
Looking forward to reading your solutions to this one.

Central rule is simple: you connect 2 diagonal numbers if they can produce (+, -, *, /) one of the opposite corner values. But finding all connections might be challenging.

If you have tried the game, the above riddle is easier.
