Default Simon Tatham's Puzzle Collection

I'm whiling away many a spare minute on this set of puzzles.

Simon Tatham's Portable Puzzle Collection

There are versions for Windows, Linux, OS X 10.3, and Palm on his site. There's a port for Symbian UIQ3 here or here, so I can play the puzzles on my phone as well (and look like I'm urgently rearranging client meetings). You can also get it, it would appear, for Nintendo and PocketPC/Windows Mobile.



Includes well-known puzzles like Sudoku and Fifteen, and some unique ... and mighty puzzling ... puzzles. No shooting, no jumping, no penguins, and no online multiplayer role-playing versions.

I'm finding that cube game impossible. Is there a strategy?

I've tried the cube game but not very seriously. There has to be a strategy but I don't know what it is.

I couldn't ever get a handle on Light Up. Galaxies is definitely one of my faves! Haven't tried Map yet.

Untangle is great. I can solve every puzzle I've tried quickly, but I couldn't explain what I'm doing. It just seems to work out.

* ceptimus agrees with JoeP.

* ceptimus has been trying to work out an algorithm to solve untangle. This is more fun than actually untangling by hand...

There's really an algorithm? I thought it was just move the balls to the opposite side to uncross the lines.

Well that's basically it, but sometimes a simple algorithm like that seems to get stuck in a loop, and you have to radically rearrange the points to get anywhere.

Try playing the game with more points and you'll see what I mean. Go to the Type menu, choose Custom... and try, say, 50 points.

What I'd posted, by the way, was that you should select any point that had lines radiating from it that crossed other lines. Then you should move that point to each of the adjacent areas (crossing one line) and choose that area which results in the greatest reduction in line crossing count. Keep moving the same point till no further reduction is possible by moving it to any adjacent area, and then choose another point to move and repeat till the puzzle is solved.

In practice you also have to move the points around to create a bit more room to work with, but as you can do this without altering the topology of the mesh (I mean without altering the number of line crossings in any way), then it is just a practical consideration that doesn't affect the logic of the algorithm.

But there are certain pathological arrangements that can't be solved by this simple algorithm - which is why I deleted my post.

It's only fun with a custom number of points, the default ones are too easy. Here's a 100 point one (and no silly algorithms for me :P )



Edit: Woot, 200 down

Yeah, Untangle is fun with high numbers.
I did 100 in about 15minutes
Then I tried 150 and got bogged down.

Thanks for the cool puzzles!

Default Re: Simon Tatham's Puzzle Collection

Okay, I see what you guys mean. I had just been playing the default, 10 points, and it was boringly easy. I just tried it at 25 and had the aha moment. I'm trying it at 50 now. Whee!

Edit: 50 done in 10 minutes. Now trying 100. Whee!

Edit: Shit, you guys! It's too big for my screen. With 50 I had to hide the dock to get to the bottom dots, but at 100 I can't do it at all. :sadcheer: Any suggestions from mac users?

Can't you resize the mac version? With the Windows version you can resize the window in the normal way. :dunno:

It looks like it is too big for her screen. She'd have to increase her resolution. Can you increase your resolution any?

My resolution is all the way up. I only have a 14-inch monitor. I think I could resize the window by grabbing the lower-right corner and dragging it up, but I can't get to the corner. :doh: My only other option, as far as I can tell, is to minimize it to the dock. :shrug:

Aren't there any mac key combinations that allow you to resize or move windows without using the mouse? On a PC you can press Alt + spacebar, then S, and then use the cursor keys to move the top/bottom/left/right edges of the active window - even if they are beyond the boundaries of the desktop.

ETA: I don't know if this free keyboard driven window mover for Mac OS X could be of any use? :dunno:

* ceptimus knows nothing of macs :blush:

Hey! That's a neat software. Won't let me move anything beyond the bounds of the screen, but still pretty cool. :thumbup:
