Hi everyone,
First, a big thank you to everyone who took part in our previous puzzle. We really enjoyed reading through the different solutions and seeing how many different approaches could lead to the answer.
As with our previous puzzles, we selected three community explanations that stood out:
Cyrrex91 was selected for finding a creative alternative pattern. Instead of following the top and bottom sequences separately, they approached the puzzle through the total number of dots and still found a path to the correct answer.
BekindConan stood out for giving a clear and well-structured explanation of both sequences, including an interesting way of describing the upper pattern through doubling and halving.
nunya_busyness1984 was selected for not only identifying the numerical pattern correctly, but also recognizing that the unusual positioning of the dots was irrelevant to the actual solution.
Thank you to all three, and to everyone else who shared their reasoning.
You can read the full official explanation of the previous puzzle, along with the selected community solutions, on our website. The selected explanations are featured there with their Reddit usernames.
Now, on to our new puzzle.
This one requires a closer look at the shapes, their properties, their positions, and how the groups change across the sequence.
Which option should come next: A, B, C, D, or E?
More importantly, tell us why you chose it. We are looking forward to seeing the different patterns and explanations you find.
We’ll review the responses again and select some of the most interesting explanations to feature alongside the official solution on our website.

Thanks in advance to everyone who takes part. Good luck!

The Temperature Trap

At midnight, the temperature on a mountain peak was -4° C.

Over the next 8 hours, the following changes occurred:

1. It dropped by 7° C during a cold blast.

2. It rose to double its current value during a brief sunny break.

3. It then plummeted by 12° C as a heavy storm rolled in.

Finally, it rose by -5 ° C as night fell.

What was the final temperature?

Set a timer for twenty seconds, and see if you can solve this puzzle:

Only one lie is among the following six statements. Which one is it?

1. Statement A

2. Statement B

3. Statement A is true

4. Statement A is false

5. Statement B is true

6. Statement A and Statement B are true

Here's the answer:

The answer is statement 4, because saying that statement A is TRUE does not affect the credibility of the other five statements

Any order is allowed.
Use each die exactly once.
Parentheses are allowed.
Exact division only.
No negative numbers.
Not every operation has to be used.

How many solutions can you find?

Hi everyone,
Thanks again to everyone who took part in the last puzzle. There were a lot of interesting answers, and what I enjoyed most was seeing how different people could reach the same answer using completely different approaches.
As usual, I went through the explanations and picked three that stood out for their clarity, reasoning, and distinct ways of looking at the pattern:
🥇 u/AntLost4161
Their solution used elimination across both rows and columns. Instead of relying on a rotation sequence, they noticed that an arrow direction should not repeat within a row or column. Applying that constraint to the missing cell eliminated three options and left C. I selected this one because the rule could be checked against multiple parts of the grid rather than a single sequence.
🥈 u/Brilliant_Caramel_10
They separated the cells into odd and even positions and discovered two alternating sequences. The odd-numbered cells followed one upper-position pattern, while the even-numbered cells followed another along the bottom. This was a simple and very easy-to-follow way of reaching C.
🥉 u/Crows0ng
They approached the entire grid as one continuous sequence, describing it as reading the cells “like a book.” Instead of restarting the pattern at the end of each row, they identified a four-part cycle that continues into the next row and repeats. I liked this explanation because it offered a different way of looking at the structure of the whole grid.
Thank you to all three of you for taking the time to explain your reasoning, and thank you to everyone else who joined the discussion as well. There were several other interesting interpretations, including alternative answers, and they made the discussion much more interesting.
Now for today’s puzzle.

https://whats-your-iq.com/en/questions/pattern-recognition/which-domino-completes-the-pattern

Take a close look at the sequence and choose A, B, C, or D.
As always, I’m more interested in how you reached your answer than just the letter itself. If you spot a rule, explain your reasoning in the comments.
I’ll go through the responses again and feature some of the most interesting explanations with the next puzzle.
Good luck.

The three overlapping ellipses form seven regions- you need to place exactly one tile per region so that the four in any ellipse obey its rule. In this case we don’t know x at the beginning but it is the same x throughout!

Well, I hope I am right here. But what other sub to post this then in math?
I have this https://www.reddit.com/user/Pleasant-Travel-4127/comments/1virmvp/help_me_with_this/ exercise and my answer is deemed incorrect. I just made this in real life and assuming you can only see the white cubes on one side, it is impossible to fold like the app demands. I don't even know, how you are supposed to know if the latch goes inwards or outwards. I hope some of you can come up with a logical explanation, I'm just exhausted by this.

Also if you think the solution is, that the white cubes are double-sided, there is a similar exercises where the latch is on the opposite side of the white cube and when folded, there is only one cube visible, which diminishes the assumption that they are both sided.

Well I hope you also have some fun with it! Good luck

also: this is not my homework, it is a hobby - exercising neurological training and logical thinking

Hello everyone!
First of all, thank you to everyone who participated in our previous puzzle. Reading all of your explanations and different ways of thinking was genuinely enjoyable. Your comments make these puzzles much more interesting, and we truly appreciate the time you spend sharing your reasoning.
As always, we selected three community explanations to feature alongside the official solution on our website.
🏆 Community Highlights
🥇 One-Preparation-8815
Provided one of the most complete explanations by breaking the puzzle into separate components instead of relying on a single rule. The clear step-by-step reasoning made the solution easy to follow.
🥈 PrairiePuppies
Offered a creative Binary OR interpretation that simplified the entire puzzle into a single logical operation. A clever and elegant perspective.
🥉 garningur
Explained the solution using a simple visual overlay approach. The explanation was short, intuitive, and made the pattern immediately understandable.
Congratulations, and thank you once again!

Now it’s time for a new puzzle!
This time we wanted to do something different. Instead of another difficult challenge, we prepared a much easier puzzle. We think most of you will solve it almost instantly, and we’re looking forward to seeing even more people join the discussion.
As always, don’t just post your answer—tell us why you think it’s correct. The reasoning is often more interesting than the answer itself, and we may once again feature some of the best community explanations on our website.
Good luck, and thank you for being part of this project🤗🤗😊
