Puzzle Description:

The top of a roller coaster, just before the plunge.

A tutorial is at http://infrapinklizzard.deviantart.com/art/Logic-High-Point-179421245

wow...your own site, Joe? coolness

Just from looking at it, you can easily see that there will be some sort of symmetri. That helps, a lot.

Symmetry did it for me. I didn't initially recognize the image. The description made me grin. I loved it! :o)

Tom, it's my own corner of a huge art site.

I see the difficulty rating has gone down due to the symmetry, but solving this with only logic is MUCH harder.

Symmetry is not PuristApproved™ logic. It can be used to some extent if you *know* the puzzle has a unique solution, but this site allows non-unique puzzles. Therefore, it amounts to guessing.

Yes, I'm a logic geek.

Thanks, Mrs Thing. I rotated it a few times to see if it looked like anything because I really just made it for the logic.

knowing this to be a logically solvable puzzle i didnt use symmetry
great solve

What Bugaboo said. I'm one of those approving purists. :)

Not a roller coaster fan, but cool.

Thanks fellow geeks.

And I'm no longer much of a fan of them either, Jota. My ears are perpetually stuffed up thanks to my cats (whom I am mildly allergic to) and so my sense of balance is whack. Worse than roller coasters, tho, is merry-go-rounds. XP

tilt - a - worlds are the worse

I have never gotten onto a ride that spins me in two directions at once since a disastrous ride on a scrambler as a child.

i absolutely hate spinning rides
most roller coasters are fine though

My favorite coaster ride was Space Mountain in Disney World. I was 8.

The coolest part was that it was dark with only pinpoints of light. You had no idea in what direction you were going to go next.

i went on the one at disneyland
same thing
very fun ride

I love the Tilt-a-Whirl. I don't really get along with rides that employ gravity to make my stomach go up into my throat, but give me a good spin and I'm there.

I have never been to Disney ... You can now understand me a bit better don't you?

I don't know why we went to Disney World since we never watched Disney cartoons or anything. My favorite parts were Space Mountain and the haunted house. The Pirates of the Caribbean ride was closed. :(

Even at eight years old I was horrified by It's a Small World. [shudder]

don't understand all the symmetry nonsense - completely solvable with logic - who marks these as guessing needed???

Found to be logically solvable by Gator.

@17 - my 7 and 9 year olds loved It's a Small World. :)

Couple years ago the boat I was on on It's a Small World sank. People didn't follow directions getting in and it became from heavy.:)

Incidentally, the last ride we did on It's a Small World was during a thunderstorm. Some of the Animatronics were still going, others were not, and all of the music was off. It was pretty creepy. Then they stopped the ride and we were in the boat for about 30 minutes (with all of the creepiness still going on around us). They finally let us out of the boat, and then we waited another 45 minutes or so on the exit ramp for the storm to die down.

So, my experience was https://www.youtube.com/watch?v=X81AoBcVnaA
while yours was http://www.youtube.com/watch?v=uTsRUIVv2WM#t=1m25s.

And your kids weren't disturbed? O_o

Yes, they were a little at the time, but if you ask them now they will say it was there favorite ride. Go figure...

When I took my kids on "It's a Small World" I was too busy being awed by the nightmare it must be to maintain the thing - millions of moving parts in a humid environment - to have time to get particularly freaked out. To have it break down would have been a mere reassertion of normality. The ride that broke down around us was "Ellen's Energy Adventure" which had no excuse, being technically much simpler.

Whenever I think of "It's a Small World," I think of Lisa Simpson drinking the water at the Duff Gardens version and winding up proclaiming herself the Lizard Queen.

As much as I squint, I still see a smiley face, not a roller coaster. I'm happy about figuring this one out, that adding logic is more complicated than I usually go.

Love the logic, like the image!

Thanks, Diana & Kadou. This was a fun one.

Really fun solve, thanks for the puzzle! Did it a bit differently than the tutorial - used the 1s columns 3 & 8 to figure out where the 4 in row 5 went.

August, could you be more specific? I don't see how to do that without invoking symmetry.

I enjoyed this a lot--I went with boring lookahead on the 6, but I prefer seeing solutions like your where you calculate something. The 3x smile logic is a neat addition too.
