Factorial Calculator

Difficulty: Expert

Game Overview

Design a physical track where a marble rolls and executes programming instructions. The marble carries a value and performs calculations as it hits different track pieces.

Puzzle

Calculate the factorial of 4 (4! = 4 × 3 × 2 × 1) and output the result 24.

Starting Conditions:

• Marble begins carrying the value: 4
• Expected output: 24

Available Track Pieces (Use Each Once):

• 2× CURVE - Changes marble direction 90°
• 1× STRAIGHT - Continues marble in same direction
• 1× LOOP-TRACK - Connects track to form a physical loop
• 1× BRANCH-ZERO - Marble goes LEFT if carrying 0, RIGHT otherwise
• 1× SUBTRACT-1 - Subtracts 1 from marble's value
• 1× MULTIPLY - Multiplies marble's value by memory slot A
• 1× STORE-A - Saves marble's current value to memory slot A
• **1× LOAD-A

Game Description:

PaperBugs is a puzzle where you control bugs on a grid by writing a simple program. Each bug executes the same program step-by-step to reach their targets. The key challenge is that ALL bugs run the SAME program simultaneously!

Puzzle:

Available instructions:

• MOVE - move forward one cell
• LEFT / RIGHT - rotate 90 degrees
• IF FLOWER - execute next line only if flower ahead
• IF EMPTY - execute next line only if path clear
• IF WALL - execute next line only if wall ahead
• IF GEM - execute next line only if gem ahead

Board:

Legend:

• Flower (blocks movement)
• Gem (collectable)
• Wall (blocks movement)

Goal:

Write a single program that guides both bugs to collect gems and reach their targets safely.

… the missing element that completes a pattern …

I just read (most of) "To mock a mockingbird" and I really love the concept of combining puzzles with fiction. I've heard that "Alice in Wonderland" has some puzzles too. I've also just watched "Ludwig", which has an element of puzzles. Can you recommend any works that combine fiction and puzzles ? :)

Preferably more like "To mock a mockingbird" which has a heavy emphasis on the puzzle aspect :)

Also,a quick note. I don't feel like mentioning "To mock a mockingbird" and "Alice in Wonderland" without a disclaimer. The only women who appear in "To mock a mockingbird" only appear to be admired by the men and to cook for them. It could have much better diversity. "Alice in Wonderland" is written by Lewis Carroll who might be too fond of little girls (https://news.artnet.com/art-world/was-lewis-carroll-a-pedophile-his-photographs-suggest-so-237222).

I know the issue is with the starred row, but I can't figure out how to reconcile it!

UPDATE: I tried a nonocross solver that told me there's no solution. If you add one-more-one to the starred row, there is a solution that aligns with a sensible visual pattern. So my understanding is that this puzzle just has a typo. Thank you for reading though!

I've been looking through so many clones (and I expect we'll see even more coming now) for a self-hosted alternative that also only has a single daily word that you can play only once. Some come very close, but all allow you to replay the same game multiple times, and that takes away the competitive part I have going with some friends (yes I suppose you could just switch browsers too).

But as Wordle is actually locally executed Javascript, and it's collection of words are also stored there, you can save the whole Javascript package to a folder, and just click to open the page file to continue playing the game as it exists right now. I tested this with Firefox and Edge browsers, and it worked fine. Brave however has some block for local files, so it did not work with that browser.

To do it:

• Go to the Wordle online page.
• Right-click and choose "Save Page" or "Save As".
• Then choose "Web page, Complete" (this ensures not just the page itself is downloaded, and includes supporting J

Honestly the main reason I'm posting this is that I find fascinating that there are little audio clips sprinkled throughout the way people use GIFs. I can think of reasons why this isn't more broadly done, but I still... love it?
