If someone could check my entry for #1, it would be appreciated. I can't really explain it here without giving away part of the solution, but I think the error there should be fairly clear to someone who looks at it. (Unfortunately, the other 0's I submitted are all legitimately incorrect solutions )

Thanks to David for the interesting puzzle set, and especially to everyone affiliated with LMI who contributes to administering these contests every month.

David and Deb

Great test, lots of fun, although as a Maths teacher, I could have done with less adding up.

Time seemed fine to me - I wouldn't expect to finish one of these (and I didn't, obviously) - maybe 60 minutes would have been better, but I still wouldn't have caught the thing that caused me to waste a lot of time on one puzzle (won't say what for fear of spoilers)

Cheers

Very enjoyable set of tests.

I realise I have entered the incorrect key for #4. I entered the bottom row of both puzzles rather than the 3rd row of the right hand puzzle. I'm relatively confident I have the correct solution, although of course won't give it away here. Any chance of rescuing some points for that puzzle???

Would it be possible to check my answer to #7? I separated lines by commas and the system did not like it. Thanks.

Dave, thanks for a very nice set of puzzles! I will definitely finish the remaining ones not to miss any fun :-).

Hi Deb -
I also entered the yellow-outlined areas on #4 as my answers ....

In any case, compliments to David for some very clever puzzles (I ran out of time, so I will enjoy Deb's ESB later).

Best regards

Dave

Aw, I had my first typo when entering one of the FLIP 'n' Fills. And it knocked me down a bonus point bracket!

If it helps, my typo implies that a number ending in a 0 was flipped (which is clearly false). But I can understand being strict about this, and it's not like I'm really in contention for a top score anyway.

Deb - I think there's a bug with regards to the puzzle rating system. I can't seem to give a rating for the two puzzles I had a manual override on the score.

For what it's worth, I thought #3 was a 6/10 and #12 was an 8/10.

Will have a look before next test. For now, I've added your ratings for the two specified puzzles.

Correct answer 2FGHJ. Your answer 2FGHI.
Marked correct.

Many players did this. Given points to both you and others

Checked all submissions for manual overrides. There is none as far as I can see.
Results are frozen now.

Admin, I think willwc's point is that there is no row I: the rows read ABCDEFGHJK. So by "I" he meant "the thing after H".

Congratulations to Thomas Snyder and Hideaki Jo for topping in FLIP. Only 2 players to complete, and by what a margin - 18 minutes remaining. Only few seconds separating them apart.
Nikola continued his trend of single-puzzle-mistake from Renban. He would have otherwise got 9 minutes bonus.

In Indian ladder, Rakesh converted his 'good performance in Renban' into a 'great performance in FLIP'. And we've Keshava at 3rd position among Indian participants. Well done, Keshava and hope to see you do better in upcoming tests.

That was careless from me. Sorry willwc. Thanks ostroffj for pointing.
3 players did the same mistake.

All of them get full points.
willwc's score is 360 now, and he moves to 15th position.

Slightly lesser participants compared to the last two LMI tests.
98 out of 115 players got non-zero scores. Thank you everyone for participating.

Those who could not participate should try to solve and enjoy the puzzles at leisure.

And I don't suppose I could get credit for #3? It was the same kind of mistake, though less clear cut: instead of "K" I wrote "J", which unfortunately is an actual row. But then, if the last row ends in a 1, then I couldn't have thought J was flipped, or else that answer would be a two-digit number starting with a zero.

Thank you to everyone who participated in the test and for the feedback afterward.

I'm sorry that the test was so short. Given the number of other tests going on this past weekend as well as over the last couple of weeks and upcoming weeks, I thought that a shorter, simpler test would be appreciated. I also hoped a shorter test would inspire more people to give the test a try.

I'm glad to see that many of the puzzles were well-liked. From what I can gather, the FLIP Mirror 0-2-5 were among the favorites, so perhaps I'll make more of those to put on The Griddle when I have some spare time.

Thanks again to all!

David

@ostroffj: In the other cases, it was clear that the answer was incorrectly entered since no row called 'I' exists. In your answer, since a row called 'J' exists, it would be unfair to give credit since it was not clear if that was your intended answer or if it was a typo. It is not a personal decision, but to be fair we cannot award you those points.

In any of my future tests with LMI, I will be sure to very clearly label rows as needed, and will only accept the correct answer as indicated by the Instruction Booklet to ensure that the scores given to all are fair.

I very much appreciated that the test was short. I'm far more able to do an hour-long test. I mean, I can now finish it while my wife is watching some TV show I don't like!

David and LMI team for conducting such a nice contest I enjoyed the puzzles which involved math a lot. I liked the fences puzzle a lot also. I must say it is a very well designed one. Even I did not try to solve the ESB during the test I must also say that it is a good constructed one. Actually I usually make some errors while solving such puzzles in a short time. These are not my type I think. But I enjoyed solving this one after the test. Conrats to all toppers and every participant.

Regards,

Zafer

I was also a fan of the test's length, even though it certainly flew by. I didn't learn about the test until Sunday morning, and only had about 90 minutes of consecutive free time in which to participate, so much longer and I would've been right out.

I was just looking at the results. One surprising observation was regarding FLIP Strips.

It seemed a very easy puzzle to me. Just add the numbers on the left - you get 90. And when you add the strips, you get 91. So it is very clear that a 1 has to go. After that it is trivial. But this was attempted by the fewest number of participants - even less than the two 65-pointers !!

This was one of the two outcomes I expected. I thought either it would be found as too easy or as too difficult depending on if a particular solver figured out the trick or not. Between FLIP Strips and FLIP 'n' Fill Sequence, I think those puzzles were good challenges for me to make something non-grid-based (and possibly good to make more for posting on The Griddle), but would be bad in a competition setting since everyone is used to not doing so much math.

(Random side thought though, I was thinking of releasing a special edition combined IB/PB with added notes/commentary, answer keys for the test puzzles, and possibly extra puzzles in the types most well-liked by test-takers. Would anyone be interested in something like this, or would it be a waste of time?)

David, I think thats a good idea. We never had thought abt having anything like that for any test.
You can also include some general stats from the score page.
Of course, many players would be interested in the extra puzzles :-)

Looking forward to your special edition!
