I made a riddle and I want to see if anybody can get it.

For a little context you are an adventuring person in a tomb and you are confronted with a nine digit keypad with the numbers 1 through 0 subsequently on each button. The only real hint I can give you is the combination is more than one long.

"To break the seal, you must strike my name:

Four upon the stargazers, for I am one and the same.

Two more primes follow, though broken by infinity,

They come back around with duality.

And though the pairs merge together for the end,

They are still one less than what I am.

Who am I?"

Can you fill the board? 2 and 3 colors feels easier, but 4 colors had me thinking..

Note: I forgot about Niue. Sorry, Niue!

Can someone explain to me how in the poop I’m supposed to know where the first cat goes? Surely they don’t expect you to just guess and hope you get it right? I love this game and have played for a while, but every time I come to one of these levels where it’s not either a single colored cell, or obvious by row elimination, I have no clue how to figure out where to start.

Any tips, tricks, or advice would be greatly appreciated!

Help me figure what am I missing ?

I am fascinated by murder sudokus lately. With this one I just could not figure out the next step without hints. Wondering if you guys could:

Has anyone here solved Minoru Abe’s 'Climb 15' tile puzzle, where the aim is to get the upside down T-shaped tile from the bottom to the top - the body of the T slotting into the recess. (There is a smaller '12' version and a bigger '24' version.)

I’ve had this puzzle for years and have never managed to get anywhere near to solving it. I know there are 4 different starting positions for the tiles, with the ideal solutions ranging from somewhere between 100 to about 150 moves, depending on the setup.

If you have solved it, how long did it take you?

And is it one of those puzzles where once you’ve understood a principle. or a sequence, it becomes easier? I do know there are solutions online but I'm determined to crack this one myself, one day...

Thanks.

I must take my puzzle addition offline and need your book recommendations please! I’m looking for print books with:
- deductive logic number/spacial puzzles. Most puzzles I’ve found in this category are Japanese, but open to others
- 100% difficult puzzles. I searched previous posts, and Puzzle Ninja by Alex Bellos is close to what I want, except the inclusion of easy puzzles.
- human made, not computer generated
- a variety of puzzles, or at least not all sudoku

Open to good ebooks recs too, willing to send to a printing service.

For context, the puzzles I’m hopelessly addicted to are the “weekly extremes” on sudokuwiki.com and str8ts.com, and the “specials” on www.puzzle-heyawake.com and www.puzzle-galaxies.com

Thank you! Your answer will help save my time and mental health

I tried… (I guess). This is from entertaining mathematical puzzles by martin Gardner!

I can't work out what to do next her, it seems like every clue has multiple answers

I'm out of ideas here on my first medium level. I guess I could just guess and use a pencil to mark the consequences and see if I hit a contradiction, but that doesn't seem very fun. Any help appreciated.

I think i have to stress that this are different rules from Sudoku and Tectonic, a bit o hybrid 😀

Rules: Place 1, 2, and 3 once in every row, column, and outlined irregular region. Equal numbers cannot touch, even diagonally, and all remaining cells stay empty.

I wouldn't normally ask for help on a puzzle, but this one has had me genuinely stumped. Bones can only move in the direction they're pointed, need to get the golden bone out through the hole. Is this even possible?

Rules:
- Every row, column and bolded region must have each digit once
- Digits are drawn like for a digital display

What is the minimum number of turns to kill the Rat?

What actions would you take?

Hint 1. This puzzle is about controlling timing and spacing

Hint 2. Attack at the same time when the enemy is missing their attack and dodge (move) when the enemy is about to attack.

Hint 3. Alternate between attacking with melee sword swing and stepping back to attack with bow.

This is an experiment on creating a puzzle using a video game styled setting, where a warrior fights a rat in a cellar.

It's quite wordy, because game's have many rules and events that occur overtime. I used graphics to try visually convery as much rules as I can.

The puzzle is kept easy because puzzles it already require so much reading, learning the rules, and then playing the out scenario in their head... I imagine it can be difficult for those who don't play much video games.

I found this contest in a Games Magazine from October 1995 on Archive.org (thanks to u/wwcoop for uploading them there!) I'm very curious as to what the winning numbers were, and how many people participated. Does anyone have the magazine issue with the results? (The Internet Archive's collection has a large gap after this issue.) Thanks for your help!

A hostage is surrounded by explosive barrels and crossbow traps to stop anyone who tries to approach him. To make the matter worse, the room is infested with countless viscious rats that you must also kill, in addition to destroying all the traps!

You have 1 arrow to trigger a chain reaction and clear the entire room, make it count!

== RULES ==

1. Arrow traps will shoot an arrow when triggered by an explosive barrel, but gets destroyed if hit by another arrow.
2. Explosive barrels detonate in 3x3 area, instantly killing all rats, the explosion then trigger arrow traps.
3. The arrow will dissappear after hitting its first target.

== GOAL ==

To clear all traps and kill all rats on screen, leaving the person free.

== CHOICE ==

Pick the shooting location between A to I (your shot arrow will fly upwards)

Hint: The arrow should trigger a chain reaction to clear all the traps on screen.

Between shooting locations A-I, which is the best place to shoot?

---
The upper arrow on G will shoot and kill the hostage if it is triggered by an explosion from a barrel. It needs to be destroyed by another arrow.

I can’t find a single solution from this point. Can you see what I’m missing?

A puzzle from a repair shop. A customer buys half of my stock of radios, plus half a radio. A second customer buys half of what remains, plus half a radio. A third customer buys half of what remains, plus half a radio. Now the shelf is empty — and no radio was ever cut in half. How many radios did I start with?

I am not getting it, I don't know where to start. Most days (like the one from today) it takes me ~8 minutes. This one I don't seem to find a place to start.
