Country : India | Some notes about April Contest 2026Please note this contest will have a slightly different format than regular LMI tests.
Key differences from regular LMI tests:
1. There is no IB (i.e. no Instructions Booklet). If you have any questions about any puzzle, please ask here in the forum.
2. The PB (Puzzle Booklet) does not have any password.
3. You can download the pdf when the contest starts and start solving. Login at the contest page and click on "Start test" to start submitting.
4. There is no time limit other than the 10 day duration. You can submit until the contest ends.
5. There will be some optimizer puzzles. Other puzzles will be very hard (compared to regular LMI tests)
6. Same scores will have same rank (i.e. early submissions do not count towards rank)
Other important points:
7. There shall be no online solving interface (like penpa) provided for this test.
8. The score page shall be made available later.
9. There shall be 10 pages in the Puzzle Booklet.
10. Participants can submit answers any number of times. The last submission shall be considered for scoring.
11. There shall be no separate notification on submitting answers.

#12 Azure and Rose Optimum: Same question. |

Country : China | In the first puzzle, does the "overlap" in "may intersect or overlap" means that one orthogon completely contains another? |

I think there is utility in keeping it restricted in case someone wants to verify their solution following the rules, or comment on a solve path - unrestricting individual posts is easy, just a button. |

One orthogon can completely contain another. |

Country : United States | mstang posted @ 2026-04-20 4:41 AM (puzzle 4) What is meant by "loop that does not touch or intersect itself"? Is it like a Snake, where (copying from GP rules) "if two cells in the snake touch orthogonally, then they must be exactly one cell apart along the path of the snake, and if two cells in the snake touch diagonally, then they must be exactly two cells apart along the path of the snake"?
Also, there must be only one loop, right? The second to last sentence says "each circle belongs to a loop" (not "the loop").

Your understanding for the loop is correct, it is a snake-like loop.
'A' vs 'the' is just translation issues that I missed, only one loop. |

When transferring, select one of the two options that are suitable for you. |

3: good questrion, and is the Jigsaw puzzle independently unique or is one supposed to find a solution that works for the Pentoloop?
11: What is meant by this "Words should read from left to right and right to left, or top to bottom and bottom to top. " why are and and or used interchangeably? I interpret it as you can only use both directions horizontally, or only vertically.
10: "Does not touch itself" is not ambiguous. Diagonal ?
Pieces can be repeated?
3. At the very top of the page it says "solve two related puzzles".
11. Words can be read in any of the 4 directions, as in the example.
10. The standard rule for the loop: Loop does not touch or intersect itself. In the example, the V pentomino is used twice. In this sense, it is possible to repeat. But there is no third V pentomino among the 14 given pentominoes. Therefore, you cannot use the V pentomino three times. |
