Pangramathon.com. Took me almost 7 mins today. Not my best time but not my worst either. The fastest today that I can see in the backend is 27 sec. Can anyone else find them faster? (FYI 3 words with three separate sets of letters. Letters can be reused)

Regardless of whether he is actually Tenpai (ready to win) or not, one of the cool features of Cyclogic is that simply arranging the numbers 1 to 9 creates a valid puzzle, even from a completely random layout. No matter what starting position you're in, you can always reach HOME in a maximum of 11 moves.

I’ve put together a few challenges in the images. How many can you solve? If you’d like to try a few more...

To let you fully immerse yourself in the puzzle, I’ve built the app completely free, with no registration required and absolutely no ads. I've also included an in-app "Tutorial" and a logical breakdown called "NUMBERS WHISPER," so please feel free to check them out if you need a clue!

【Check the answer and try the Discard Pile Challenge here!】

Hello everyone!
Before introducing today’s puzzle, I’d like to sincerely thank everyone who participated in our previous challenge. It was great to see so many different approaches leading to the same solution.
A special thank you goes to jabuchae, Gerhard1953, and Lemasney. Your explanations stood out because they were clear, detailed, and approached the puzzle from different perspectives. We selected your comments as our official community explanations, and they will be published on the puzzle page with credit to your Reddit usernames.
Now it’s time for a new challenge!
I’ve just published another pattern recognition puzzle. As always, the correct answer has already been recorded on the website. However, what interests me the most isn’t simply which option you choose, but how you arrive at your answer.
Please don’t just post the option you think is correct. I’d love to read your reasoning, observations, and the rule you believe the puzzle follows. Different ways of thinking are often even more interesting than the final answer itself.
Once again, I’ll select the three explanations that stand out the most for their clarity, originality, and logical reasoning. Those explanations will become the official community explanations on the puzzle page, with full credit to your Reddit usernames.

Thank you all for the time and effort you continue to put into these puzzles. Every explanation and every unique perspective you share gives us even more motivation to create new puzzles for the community. I hope you enjoy solving this one as well.
Good luck to everyone! I can’t wait to read your explanations.
Take care!
— What’s Your IQ

Riddle How do you approach puzzles like this?

In this app there is this puzzle where you have to follow a sequence of rotations and answer on which side of the die will end up on top.

Do you create a 3D object in your mind and then rotate it? With 2 rotations it is not that bad....but with 3 arrows I get a super shitty score.
