17 is a fun one, I gave that a whirl to get down to 4 last night. So fortunately, yes I can help out

Edit: Actually read Jonts post before checking this link!

47 what the heck...

I think this is where I stop.  That was a nice diversion for the weekend.  47 is weird enough that I can't just mess around and hope to get a clue.  I'll keep it in the back of my mind though...

Edit: aaaaand right after I said that, I figured it out.

47 is just an introduction level for the concept... but if that weirded you out, check 48...

Right now this...

...is my solution to 17. It uses 5 tiles and I can't figure out how to do it with 4, could someone help me out?

You are so incredibly close. Try to find a quicker way to get the right split ball to where you want to go.

You have figured it out already. You just applied the method to only half of your solution.

You almost have it.  Try to be a bit more symmetric.

...My brother just got a 4-star solution.  On level 16.  He used seven tiles.

EDIT: Here's the solution (I can't get the url thing to work, just copy and paste): http://xorballs.dskl.net/#3,up,[0,new:438450538540558638648]

Woohoo! the first improvement on the scores by dominionstrategy.com
Congrats to your brother.

Why did he have to improve a level where I was holding the best score?

If only levels where you aren't holding the top score werent in short supply.

I 3-starred it!

And I got 48, except it took 15 tiles.  But now that I've found the optimal solution for 47, I'm trying to optimize 48.

But it is late and I really really really should go to bed and then actually do other things this week, so I am going to try to avoid this game for a while.  Ugh.

[Ozle]

it took me several minutes to work out that the bottom half of the screen was showing the level and the top half was the components....not sure I shall get too far in this!

This is amazing. How did he get that?

My own effort gives me 8: from symmetry arguments I can sort of say that this requires 3 splitters and 1 "time-reversal-breaking" rotations if the solution is small enough. (My solution is equivalent for the 5 tiles at the left; notice the lower-left splitter is not  necessary and can just be a yellow line.) Those 5 tiles gives the correct output except for the top input.

Adding the 2 tiles on the right to correct that (by giving the path from the right to from above and form an alternative path for itself) is... amazing.

[-Stef-]

OK, I have a new challenge. On level 1, what's the highest number of tiles you can use and still win? Only rule is each tile must be used at least once. My record is 36.

EDIT: Got it up to 47. I'm feeling a bit dizzy.  http://tinyurl.com/cnozqzu

I've got 48
The start is symmetrical so no headaches there.
And I'm pretty sure the end can be improved upon but not right now.

Edit: zut it's illegal. one the middle line (horizontal) the rightmost tile is unused

He literally was just trying random things.

[Kirian]

@Kirian, I tried Spacechem recently but to be honest I found navigating the waldos too tedious to continue.

Heh.  I guess you and I have very different tastes then!  I got stuck on like level 9 or 10 and haven't really had the patience to try more.  I'd love to know what the other gadgets are, but apparently I can only make left and right turns for now.

With a bit more time I got to 51.
Not at all certain this is max though.

Edit: Nope, 54 is definitely more.

[sudgy]

David, my brother said he would want to be called, "drbop".

[David]

Done!

[sudgy]

Wait, has nobody beaten level 60 yet?

[David]

Level 60 has no solution.
There will be more levels, but the last level is always a placeholder just so you can continue playing around with tiles.

[heron]

Well, I only needed 53 tiles for level 20 

[sudgy]

I'm not sure what happened, but now (I'm on level 55) when it fails to work, one of the custom tiles (the solution to level 48) stops working.  If I run that tile by itself the main one works again.

EDIT: And now other ones do the same thing.  I can still play, it's just annoying.

[sudgy]

And wow.  That was weird.  It glitched on the testing, and I just ran it again and it worked...

[Drab Emordnilap]

This game is amazing. It makes me feel smart and stupid at the same time.

[David]

@sudgy: I'm not following you. If you can reproduce the problem, can you be more specific about what's going wrong?

@Drab Emordnilap: Awesome! Can I use that quote?

[Drab Emordnilap]

Go for it.

[jonts26]

I feel like I'm only capable of the kludgiest of solutions. Took me 14 tiles to beat lvl 48 and 16 for 49. Question for those who have efficient solutions for lvl40+ levels - do you use a lot f custom tiles? I find I don't really bother often and not sure how helpful they really are.

Also what is your methodology. I find myself, especially for the more complicated later levels, trying to think of what I want to do at each step modularly and then do it. But it's really hard to simplify the solution and allow a lot of tiles to pull double duty that way.

[Drab Emordnilap]

Just a note -- don't fill the entire field with splitter tiles, if you value your computer's memory.
