I really don't like that the rules changed between the Instruction Book and Puzzle Book for Arithmetic Square. Three more sentences were added!
There are many non-native-English speakers doing these contests, who may have difficulty or questions.
I found these new rules slightly ambiguous also, if the two puzzles used the same code or different codes, although eventually decided that the reference table with only one empty column pointing to both sides answered that.
I appreciate you maybe didn't want to make another example puzzle, but I think it is better to have full rules and no example (USPC does this sometimes?) then rules and example for a similar type?
This is a valid point. Perhaps it could have been handled better. However, the only area of confusion could have been whether the letters have the same value in both puzzles. And we tried to make it clear in words, and also visually. I definitely wanted the letters to be a surprise in the PB, so the IB example was more normal. There was no change in the basic rules though.
On a separate note, if we do a post-test analysis, this puzzle had a 100% correct submission rate, and also had a good 67 correct submissions, which is high in the context of this set. So, I am hoping it was understood right most of the time. |

Counting puzzles aren't difficult because logic to solve, but need time to counting all combinations. And in most cases they have a low punctuation. So, if test have several counting puzzles, time is less to solve, including time to write answers in submit page and send it. If you see results score, puzzles 2,3 and 5 had less % correct.
....
I solved Word search only after test over because I didn't see second SATE word diagonally on left side.
Thanks for a very detailed feedback. I can relate to most of your points.
For counting puzzles, ~10 minutes usefully spent should have given the 12 points. But it required "logical" counting, where the approach does not miss valid cases. But most participants gave up on counting if they got one or two incorrect answers. Some started guessing, and ultimately, counting puzzles ended up as the main contributor to the high number of penalties (39 being the highest ), and less accuracy. Maybe, I should have kept only two instead of four counting puzzles.
SATE was the intended start for #22. Unfortunately, many participants did not get enough time to attempt this. |

Congratulations to Neil Zussman, Walker Anderson, Bram de Laat and James McGowan for taking the top four places. And, a special mention for Ivan Koswara, who got the highest number of puzzles correct (20).
Among Indian participants, Congratulations to Prasanna Seshadri, Amit Sowani and Rohan Rao for taking the top 3 places.
Thanks to the 165 participants. Anzhi Liu (China) was the first to take the test while Anubhav Balodhi (India) was the last person to take the test. The median score of the test was 38.
Thanks Rakesh Rai for the puzzles, and all participants who provided valuable feedback.
Participants may share feedback on the results page and rate the puzzles on the contest page.
Very pleased and definitely surprised to get my first LMI win (unless I've forgotten something! ) :- ) Thanks to Rakesh for the test.
I don't think I have any comments that haven't already been said. I didn't like the Arithmetic Square twist. I think having letters is fine, but having the same letters take the same values across both puzzles was a bit weird, because usually you expect different puzzles to solve completely independently of each other. Until I solved it, I wasn't 100% sure I understood the rules correctly, so I can empathise with any non-native English speakers who were even more confused. |

There will be a solutions booklet by Saturday. However, we are not planning to include all triangles or knight paths there. To answer your query, we will try to provide a break-up of the 54 triangles for puzzle #2 separately. |

Country : Indonesia | Oh, yeah. The fact that there is extra text in PB is a bad thing because some non-native English speakers might first translate the IB to their own language or something to get more understanding. Extra text added to PB means they have to understand the extra text first, which can be a problem for some people that are not fluent in English.
I don't think I have any concern about puzzles being related now, considering that some puzzles in other tests (e.g. WPC) might have multiple grids and also partial points for solving grids, effectively making them "related puzzles" too; the only difference being the multiple grids being numbered as a single puzzle there but multiple puzzles here. |
