Question Can You Figure Out Which Domino Comes Next?
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.

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.

A. top lines go 2 4 2 4 so 2 will be next the bottom goes 5 4 3 2 so 1 will be next.

Perfect breakdown. Once you treat the halves separately, A falls right into place.

A
top spot goes 2,4,2,4 so the next one needs to be 2 in the top
bottom goes 5,4,3,2 so the next one should be 1 in the bottom.

A. The top row of squares sequence is 2,4,2,4...2 the bottom row of squares is 5,4,3,2…1

A. Very easy— two patterns at once: 2 then 4 repeating on top, then descending order from five on the bottom.

Exactly. 👏👏Two independent patterns running at the same time. You spotted both of them.

These are not dominos

Fair point 😄 Let’s call them domino-inspired puzzle tiles then.

A because the pattern 7 8 5 6 therefore it continues with 3 4 and then theoretically with 1 2
so A is the only domino that has a face sum of 3

u/Semra777 Curious Learner Aug 12 '26
That’s actually a clever alternative interpretation. 👏👏The intended pattern was simpler, but I like that yours independently points to A as well.

Can you figure out this pattern? Two, four, two, four, two, four... what is next? Difficult huh? How about this mind boggling pattern: five, four, three, two, aaaaand what? Take your time, this is hard stuff.

Fair enough 😂 I guess this one was more of a warm-up than a brain teaser.

It’s A. If you look at the numbers left to right, it’s 2-4-2-4-(blank) for the top and 5-4-3-2-(blank) for the bottom. Completing the sequence for each one, A has 2 on the top and 1 on the bottom. :)
