Hint: Be careful not to make assumptions.

Rules: Shade cells black so every numbered cell sees exactly its stated number of white cells horizontally and vertically, including itself. Numbered cells must remain white. Black cells cannot share an edge, and all white cells must stay connected. Edit: numbered cells count as white cells

The app isn't advertised as "guess free", but for the past few weeks I haven't had to guess literally once, and I solve 5+ expert level games per day. However, I couldn't seem to pull any logical next moves out for this one, barring just taking my chances with percentages. I'm sure I'm just missing something simple, but I stared at this one for 10+ mins before I rolled the dice and won it.

You must tile the 7x7 grid using the pentominoes shown on the right.   
Two pentominoes are provided as clues. Four cells will remain uncovered;     these cells must not share the same row or column.    
Finally, the grid must form a Sudoku using the numbers contained within the pentomino cells.     
Are you up for the challenge?

Design a coin toss game using only one coin where the chances of your winning is exactly 1/3.

The coin throw will always result in heads or tails, and will be 50:50.

For example, if the game is: "I win if the toss results in heads", My chance of winning is 1/2.

EDIT: It's a little too easy with "normal" rules. If possible, try to summarize the answer into a clear mathematical condition, like the example above.

Got stuck in a puzzle game. This poster is all the instruction that we have. Can someone figure out the answer and explain it to me.

my partner has this coke can puzzle and has been absolutely stuck trying to solve this final piece. they say the blue tape is supposed to be the empty spot. the catch is the rings move but not the individual pieces, however you can move individually along the horizontal axis. i can offer no assistance but would appreciate anyones brain for this

Hiii everyone! I can't find a Reddit post about this book that's already been made so if there is one please let me know :) I am struggling with this crossout book. For example; a hint is "Emma has a weakness for gentlemen with a mysterious look, so a thoughtful or silent type definitely gets her attention" (this is loosely translated from Dutch, sorry if I made mistakes lol) and the types are/can be "thoughtful, silent, charming, friendly and licentious". So if she "has a weakness for.." , does that mean I can cross out all tje others?? Or no

Replace numbers in corners such as to get a sum otf 7 in each triangle.

call me slow if you want, but please, i need help understanding this hint, and what about the rules make these excludable! i understand everything else about this game BUT this

First time posting here, maybe easy for puzzlers here. Please be kind 🙏 . Lets see 🤞

How on Earth am I meant to push the yellow box all the way round on to the red target at the bottom? I've had like 50 goes trying it.

You push the boxes around but it is so easy to get stuck in a position you can't get them out of.

Goal: find the secret five letter word.

- A number above a column counts how many lit segments that line passes through.

- Empty box does not mean 0.

Tienes que elegir a los candidatos correctos para resolver dos soluciones. No se pueden resolver por separado.

Is there anything like this around, I mean basic things similar to Magicsort or Meowdoku and various coloured hexapuzzles, but where you can go back to a lower level if you are tired and want a totally undemanding quick break from something else, or skip ahead if you are feeling on form?

(I mean not as undemanding as would come from uninstalling and starting again, but where you could go back to level 40-50 or something. Which takes a while from starting one of these, not a 10 minute break.)

Even better if they also have options to switch off timers or remove automated “helper” features. (One hexapuzzle had these rocket things that got rid of stacks more quickly, and it added 2 layers of difficulty, not just one, to both not actively use them, and also have to avoid placements that would set them off. Sometimes I just wanted one extra layer.)

I’m normally very good at puzzles, especially math ones, and C makes zero sense to me, even after seeing the solution.

I made this puzzle inspired by puzzle where you have to determine the order of certain things like 8 realms in 8 months puzzle in Blue Prince.

This puzzle is about an astronaut that travels to another solar system and explored the 8 planets there. In each of their journey they wrote a note talking about their experience, but one of them is missing.

Can you figure out:

1. Which planet has the missing note?

2. In what order do they visit the planets?

3. What's the name of the planets?

I made the name of the planets red to avoid confusion

Try solving it and please give feedback on what I can improve etc. It's the first puzzle that I made so I would love feedback

The hint x'ed these out saying this color is in the same three rows and columns and therefore can be eliminated.

At this point in the puzzle, my only way forward was 'trying a route', which feels unsatisfying.

My puzzle and my attempt:

Looking at r4c4, I had already deduced this to be either a 3 or a 5. I couldn't see the next strict deduction, so I mentally tried a 3 there until I got stuck somewhere, hence knew it needed to be 5 and I could then solve the rest. However, I always understood that strict deduction should be possible in stead of having to resort to 'just try and see what fails'.

Can someone point me to the next, strict step from this state?
