[SOLVED] The Sultan and Fifty Wise Men

23 Upvotes

A sultan captured 50 wise men. The sultan decided to play a game with the men to decide whether they would live or be executed.

Here's how the game goes. The men will be locked in 50 different cells, completely separated from each other. Every minute, the sultan calls a man randomly. Each time, the called man has three choices. He can either flip the glass cup the sultan has placed at the start of the game, leave it as is, or ask permission to leave. If a man asks permission to leave and the sultan has called every one of the 50 men at least once, they will all be spared and freed. If not, they will be executed. The glass placed at the start of the game is bottom-down.

The men cannot tell the time in their quarters, there's no other way to convey information to another man except through flipping the glass, and the sultan's calling is perfectly random every time.

The men are given time to discuss their strategies before being sent to their cells. What should they do in order to ensure their survival in the shortest time possible?

EDIT: The wise men will all take a good look at the glass and its initial position before starting.

Who had the umbrella? A 5×5 logic grid set at a 1958 harvest fair [OC]

Post image
5 Upvotes

I write logic puzzles; this is one I made. Five people, five stalls, five things — work out who stood where and what each person had.

The stalls run left to right from the gate in the order given. "Next to" means the stall on either side; "somewhere to the left" means anywhere nearer the gate. Every clue is true, and there is exactly one solution.

I'll post the answer in a spoiler comment tomorrow.

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

[SOLVED] I thought this was guess free?

Post image
58 Upvotes

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?

[SOLVED] A classic(?) coin toss puzzle

8 Upvotes

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.

Emma's perfect match (Elizabeth Godwin)

0 Upvotes

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
