Damn! Too slow!
I also found a 5-queen solution-- a8, b4, e5, g1, h7

, your upsies, Pirate

Yay! I wonder how many possible 5-queen combinations there are that can cover the board, since mine and Taleisin's were obviously different. That would be a tough next question, but if anyone cares to figure it out, go ahead.

In the meantime, anyone who has a puzzle, post away. I'm spent for the moment.

This is a su doku puzzle. Each number appears once in each line vertically and horizontally, and once in each of the 9 3x3 boxes. Use logic to fill in the gaps. This one is rated as 'fiendish', as you are all good at this type of thing

Pirate - the better way is to prove that 4 is a minimal solution, which no-one has done yet.

Solving a puzzle to me involves a proof, but meh.

Perfection said I was correct with 5. I don't think there is a 4 queen solution. Is that what you are saying?

I meant prove 5 is a minimal solution, sorry.

You need to show that 4 queens can't cover the board, and it's not that hard...

Gagh, someone do something!

Gagh, someone do something!

How can I refuse? Here I go, doing something:





To elevate this above spam, a (lamentably easy) puzzle. How many times has Mr. Bouncy bounced since this post, to the nearest, oh... 50 bounces? Answer based on whatever the time is when you see this.

One bounce per second since 10:40 PM. I'll edit the corrrect answer in as soon as I post.

300 Bounces 60 times 5
