Glue Factory Stakes
Logic Grid puzzles come with a handy interactive grid that will help you solve the puzzle based on the given clues.
Five horses have just competed in the annual "Glue Factory Stakes". With the given clues, determine for each horse: its color, its number, its jockey, and where it finished.
Finish: Win, Place, Show, 4th, 5th
Horses: Ghoulish Pleasure, Infirm, Roughage, Seattle Slow, Secret Harriet
Colors: Black, Red, Yellow, Blue, White
Numbers: #18, #29, #37, #46, #50
Jockeys: Allen, Jerry, Luke, Nathan, Tim
1) The 5 horses are: Infirm, the horse ridden by Tim, the horse that wore black, #50, and the horse that Placed.
2) The 5 jockeys are: Allen, the one that rode Seattle Slow, the one that rode the horse that wore red, the one that rode #18, and the one that rode the horse that Showed.
3) Secret Harriet finished ahead of the horse that wore blue, which finished ahead of the horse ridden by Luke.
4) #50 finished ahead of the horse that wore white, but finished behind Roughage.
5) Jerry finished next to #37.
6) Allen finished next to #29.
7) The horse that wore blue finished two positions away from #50.
8) The horse that wore yellow finished two positions away from #46.
9) Luke finished at least two positions away from #46.
10) Nathan finished at least two positions away from #50.
11) Luke rode a horse that wore an even number.
12) Only one of the horses that wore a primary color also wore an even number.
Answer
Much of the grid can be filled using the normal process of elimination. The following explanation resolves one of the more difficult sections.
If #46 finished 5th, then the horse that wore yellow would have had to Show (clue 8), and Luke would have had to have ridden the horse that Showed (clues 3 and 9). This would mean that Luke rode the horse that wore yellow, which Showed. The horse that Showed could not wear #18 (clue 2) or #50 (clues 3, 4, and 7); Luke could not wear #27 or #39 (clue 11) or #46 (clue 9); therefore, Luke could not have ridden the horse that Showed. Thus, #46 could not have finished 5th, which means that #18 finished 5th.
Win: Secret Harriet, Black, #46, Allen
Place: Seattle Slow, Blue, #29, Nathan
Show: Roughage, Yellow, #37, Tim
4th: Ghoulish Pleasure, Red, #50, Jerry
5th: Infirm, White, #18, Luke

| Logic grid puzzles are my favorite. I normally get them very easily, but this puzzle was so confusing. There were too many "this person came before this color and this color came before this number" type clues. I had a lot of red x's on the grid but no green circles. I even tried to figure it out just on paper but I just gave myself a headache trying to figure out your puzzle. |

| When it became obvious that I was never going to solve clue #8, I gave up. Too tough for me.  |

| For those having trouble getting started on this teaser, here's my initial grid solver using a process of elimination on the individual clues alone (in other words, I've only put an X if a single clue suggests that two attributes don't belong together):

Now to get an easy match, look at clue #7 to see which colour finished in "Place" and which number finished in "4th". Good luck! |

| This was one of the most difficult puzzles I have ever done. It took several tries before I was able to get it correct. I think the difficulty rating should be much higher.  |

| very very tough, thought the rating should have been harder. Got it but it took many many tries. Thank you for the tough puzzle. |

| I worked on several days to finally get this one!  I feel almost brain-dead, but I got it after guessing on one square. (Cheating)!  I did enjoy it!  |

| WOW! What a brain workout! I actually had to print out the grid and the clues and make up my own little chart to solve this one. But...solve it, I did!!! Thanks for a really tough one. |

| After two false starts and hours of work, I finally solved this one. I didn't guess at all, but I also didn't follow the logic mentioned in the answer, so don't ask me how I did it. I guess I was just one with the grid.
Great teaser! |

| similar comment to phrebh - I did not have to resort to trial and error; but had to use some logic (of course ) to eliminate some squares.
cnmne - another excellent puzzle. |

| This one was REALLY tough, but I'm glad I saw it through because it was really fun! Like on another puzzle I did, I somehow knew who was in last place. Weird, huh? |

| Nice puzzle -- I like the hard ones. Took me a little while but all worked out. (Like the previous poster, though, I was put off by "Glue Factory" in the name!) |

I had to "check" my answers. |

| My grid was messed up, read the comments, so I guess it is my lil' old laptop that is messed up  I drew a grid by hand to do it anyway, cause there aren't nearly enough challenging teasers to waste one! I loved it, thanks very much for your work! |
