Awesome teaser. I really had to think to figure this one out. I love logic grids that are like this one. Excellent job.
I drowned! I couldn't even figure out how to use the grid on this one. I will just dry off and try again.
good one!
i liked this one keep em comin i love logic grids and this one goes up top in my book i liked that this one made me think!!!!!!!!!!
Wow. That was a tough one. Good Job! I loved it.
This took a lot of work - great challenge! At some point I realized I goofed and had to start over.
Wow, great job!
I'm definitely missing something here -- I just can't get past a certain point in this. Feel free to e-mail me with a clue or tip!
One of the best logic grids I've seen!
Ahhh to much water and it's think or swim and I think I'll swim I just can't get this but it's a good teaser.
Really, really tough. I got the breaststroke and the backstroke mixed up several times, making my grid null and void. Aagh, but I like it. I saved it to my favorites.
May I have a tylenol, please?
Phew! That was easily the toughest logic grid puzzle I've ever tackled! At first it seemed I couldn't even get a foothold, and it took a lot of thinking and rethinking, but WOW, that's an awesome puzzle. Fabulous. Well done!
best logic grid i have done!! make some more just like it. it stretched my brain and that feels good
I did it - but had to guess on the winner in breaststroke. Can you get all the answers from the clues???
I answer it myself. YES you can. I finally made it. Thank you cnmne - exellent
Really good! This one really took some thinking!
two hours and I still mixed up carl and doug.that was fun
I thought that this one was really going to be hard, and it was pretty hard, but I god so far and things just fell into place. I guess that just shows that it was a really well written puzzle. Things that seem complicated become simple when you see what is really going on....either that or else I have gone completely insane from solving 90 logic grid puzzles in the last few days!!!!!
oops I meant to say that I GOT so far not god. sorry
Finally got it after resorting to trial and error! And I thought I was pretty good at these things!
i'm so proud of myself. this is one of the few grids that really needs logic to solve it. i loved this one.
I dont know how you solved this without guessing...
this one is by far the hardest logic grid i've ever done!now my eyes hurt from trying to figure this on out and staring at this screen
Several tries and a couple hours later I figured it out. This is one of the best puzzles of done here.
Wow, this teaser is amazing. After the first time through, I thought - how will I ever figure it out with these clues? But I just kept going through the clues over and over again. I finally figured it out in an hour (with a few frustration breaks). Toward the end, things fell into place very fast.
I wish I could figure out how to write teasers this hard. Good job and thanks.

you are pure talent, man, THAT WAS UNBELIEVEBLE
that took me forever!!! but it was really good! keep 'em coming!
This was Great! Going to my favorites (and I don't have many of those!) By far the hardest I have done!
SO HARD!!! I had to give up. Great job.
Took me a while, but I got it - brilliant grid, thumbs up
One of the few logic grids that I've enjoyed (even if it was time consuming)

Great Logic Grid - I finally had to use the 1,2,3's in the logic grid to work scenarios to break this one.
Eric's finish in the backstroke was the same as Doug's in the butterfly.
Is it just me or does your answer negate this one??
Is it just me or does your answer negate this one??
nevermind ignore my stupid self... I read the wrong stroke
Very tough puzzle. I was not able to complete this straight up. Like orbrab, I had to guess the breastroke winner. Then I had to guess Eric's finish in the backstroke, which led to guessing 5th place in the freestyle. Only one scenario conformed to the clues.
oops - I meant to type breaststroke. Guess I had been looking at the logic grid too long. (spelled incorrectly on the logic grid, perhaps due to space requirements)
wow, I both love and hate these "Trial & Error" logic grids, As in testing which of 2 possibles is the winner of the breastroke, first.
Then do the IF, THEN, Else - computer logic... *sigh*

Amazing. I cannot imagine how anyone can design a puzzle like this. It is a fantastic job, and I congratulate you. Took me forever to complete. Keep them coming!
Wow, I can tell why this is the hardest logic-grid teaser on site! Fun but a real nightmare!
YEAH!!!!! I did it. I have been coming back to this one for way too long. I just had to stop and think one more time and I got it!!!! Excellent job. This goes down as one of my favorites!
I really loved this one, it gave me a workout. Thank you. Fun, fun, fun !
I finally got this on my fourth attempt over five days. I kept stuffing up and finally, finally I got it! This is a brilliant puzzle - so difficult yet so much fun.
Nice teaser! It took me almost half an hour to solve even using the logic grid--very tough.

The answer is wrong. because it said that Doug didn't place 3rd in any event and yet the answer said he did. So does anyone know the real answer?? I'm dying to know :-)

It doesn't say that Kendra - you must have misread it.
cnmne, you da man! Great puzzle, bro. Keep 'em comin'!

Best teaser ever!!! I started over 3 times and ended up with different answers each time (none of them correct), but I loved it nonetheless!
When a puzzle makes you resort to guessing because there aren't enough clues, that's lazy puzzlemaking. Also, i's either a cheap trick or a dumb choice to ahve two categories named "strokes". A simple way to blow a few minutes but there are far better logic puzzles out there.
There are enough clues to solve this teaser. There are also no tricks. However, there are no explicit pairings, such as 'Carl finished 3rd in the butterfly'. While this does require some thinking outside the box, the teaser can be solved ... logically.
Wow! That was a challenger. Good exercise. Took about 1.5 hours. Had to make a couple of different grids to be able to think about the information gathered and then cross-check from one to the other. I had tried this one months back but didn't have the time to spend. I usually like them challenging but only have a short time to figure them out. Thanks!
Amazing puzzle. For those non-believers out there this puzzle IS solveable without guessing anything at all!!! It took me a couple hours and I had to start over 3-4 times due to getting breaststroke and backstroke mixed up, but I still got it.
whoo hoo!!!!
i finally got it i'm so proud just kidding. i had to print it out but is till got it! hard, but enjoyable
i finally got it i'm so proud just kidding. i had to print it out but is till got it! hard, but enjoyable
Just because someone likes brain teasers doesnt make them a geek, just makes us someone that likes logic grids you moron and i have a great life and an awesome fiance....And even though I am still working on this teaser, it is a great one. Good work!!!
Too Hard
guys whats your iq?
I managed to do it in my head , it took me around 3-4 hours. But I had to use a it or trial and error.
Took me two hours! But worth it
This one was good. It took me a while. Each clue was very helpful. Some of the clues on some of these aren't needed. You need every one of these! My advise to those that are having a hard time: Write out each clue. As you go trough and fill in the grid and are done with a clue completely, cross it out. Then once you are finshed, go through the clues again until you find another answer and can cross out another clue, then go back to the top and go through them again. Another hint, once you start filling in the grid, decide who isn't the person in number one, until you narrow down who that is.
