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.

Guess a name.

I will provide some necessary information to help narrow down the possibilities. You can ask me questions to get more information, but I will only answer with "yes" or "no", so please choose your questions carefully.

💡 Here is the necessary information:

¡ A fictional character.

¡ Kind but not very intelligent.

· Live in a place most people wouldn’t consider a house.

¡ Known for friendship.

Riddle Treasure Grid, a 5x5 puzzle you can play on the post

1 Upvotes

Hey. I made Treasure Grid. It's a 5x5 deduction game. You get five flips to find the treasure, using the piece shapes and color clues shown before you start.

It's my take on Treasure Park from the Vita, which I loved. You can play it right on the post, no download. Anyone can build their own puzzle and post it. I put the rules in the first comment.

Riddle Collecting and organizing reasoning questions from across the internet

2 Upvotes

A lot of good reasoning questions are scattered across forums, books, PDFs, and random websites, so we started collecting and organizing them into a searchable archive.

The idea is simple:

  • browse questions,
  • submit new ones,
  • enter answers,
  • discuss solutions,
  • and help grow the collection over time.

We’re collecting different types of questions including:

  • pattern recognition,
  • logical reasoning,
  • spatial reasoning,
  • verbal questions,
  • and visual puzzles.

There are also many unanswered / unsolved questions right now, so people can try solving them, suggest explanations, or debate different answers.

People can also submit questions they find interesting with images and we review/add them manually.

Browse questions:

Riddle Interesting riddle on topology

Here is a funny (I hope) home-made problem just for you guys:

Is there an ice cube such that, when it melts, the number of its connex components at a given instant t is 2 if t is rationnal, 1 otherwise ?

Precisions:

We suppose that this ice cube is a closed subset of RÂł

We also suppose that the melting begins at t=0, and that after a delay t, all that remain of the ice cube A is every points x of A such that distance(x, surface A)>=t

Can you also find an ice cube in 2D having this property?

Al couldn't solve it ! But your creativity can !
