LMI Springs Sudoku Test : Mar 26/27 2011


On 20 March, the sun reaches the vernal equinox, heralding a symbolic revival of nature in the northern hemisphere of the planet. We, the authors of the book « Florilège de variantes de sudoku », have risen to the challenge of creating sudoku puzzles inspired by the theme of spring. Alternately playing with words (« spring » or « printemps » in French), date or trying to symbolize the fauna and flora in the different grids, alternating between classical grids, known variants or innovations to achieve this, we propose for the tournament a panel of varied grids . The process has requested to the authors an effort of imagination in order to create grids being interesting to solve and symbolizing the theme of spring. We hope you enjoy this double goal and you have as much fun to solve the grids as we had to create them.

Themed 5th Anniversary Puzzle Design Contest



To celebrate the 5th anniversary of PuzzlePicnic.com's conception, there will be a themed contest for puzzle designers. Details can be found below. We hope you will enjoy our challenge and we look forward to receiving your submissions! The deadline for submissions is June 30th, 2011
CONTEST DESCRIPTION
Your task is to design a puzzle that displays antisymmetry and somehow relates to PuzzlePicnic's 5 year anniversary in any of the genres supported by PuzzlePicnic. These themes may be interpreted liberally. For example, a puzzle in which all givens are in a symmetric position but with opposite values/colors (depending on the genre) may count as antisymmetry, or a puzzle in which positions of givens match with symmetric positions without givens and vice versa, or perhaps only givens of a certain type follow antisymmetry while another type is used normally. Here symmetry could be axial or rotation symmetry, or even refer to two small puzzles side by side. You are free to interpret the theme as you wish, but in the end it should be an elegant puzzle.

CONTEST RULES

  • Every contestant needs to be a member of PuzzlePicnic.com to participate (membership is free).

  • Every contestant is allowed two submissions.

  • Every submission must be made using the regular puzzle studio, and be accompanied by a message saying "5 year anniversary contest submission".

  • A valid email address must be present in the profile of a contestant, so PuzzlePicnic.com staff can contact contestants regarding their entries and/or prize.

  • Submissions received after June 30th, 2011 at 23:59 Honolulu time, will not be eligible to win.

  • Submissions must be the original work of the contestant alone and must not have been published or be published, online and/or in print, before October 1st, 2011, without the written consent of PuzzlePicnic.com.

  • The copyrights of a submission remain with the contestant, but the contestant will license PuzzlePicnic.com to publish the submission online and/or in print (or through any other medium as provided by our Terms of Use) and this license will be exclusive to PuzzlePicnic.com until October 1st, 2011. PuzzlePicnic.com will always credit the contestant when a submission is published.

  • Submissions will be evaluated on elegance (both visual elegance and elegance of solving) and adherence to the theme.

  • Submitted puzzles should have a unique solution. Non-uniqueness at the time of submission will negatively affect the odds of winning a prize.

  • The contest winners will be chosen subjectively by PuzzlePicnic.com admins and judges, and this decision is final.

    PRIZES
    The three best submissions will be rewarded with an exclusive PuzzlePicnic.com T-shirt.

    Website: www.puzzlefountain.com

    Download instructions
    Download puzzles
    For questions refer to: Puzzlepicnic forum
    1-2. Kenken 35+65
    3-4. Tapa 45+60
    5. Galaxy 25
    6. Heyawake 40
    7-8. Heterocut 80+90
    9. Star Battle 60

    17. Math Tapa 60
    18. Tapa Minesweeper 70
    Total 1000 points

    Some tips (thanks to players who pointed out):
    • You can visit any time your contest page and look at your solutions simply by clicking on the link, for example to find mistakes.
    • When you click on the Submit solution button, you must wait for the confirmation of data saved before clicking on a new puzzle link; otherwise your solution will be lost.
    • It's NOT a good idea to right-click on a link and open another page or tab to solve a new puzzle. This may cause loss of data (and in the worst case the applet will work no more). So don't do it!
    • You can also save partial solutions by clicking on Submit solutions (only colours will not be saved).
    • IMPORTANT: by pressing on SPACE during solving, it's possible that you delete all your numbers! Use DEL to delete a single number. SPACE works as ENTER in java, and if a DELETE COLOUR button is active, it will work. I know it's better to use SPACE (easyer to find, and puzzlers used to play in croco press it automatically), but for the moment I couldn't implement it.

    Melon's Puzzle Zoo : LMI February'11 Puzzle Test on 26/27 Feb


    Welcome to the Puzzle Zoo run by Palmer Mebane, MellowMelon, featuring a large number of unique kinds of puzzles that to the best of his knowledge made their first appearance on his website, if anywhere. Admission to the zoo is free, but you will only have two hours (120 minutes) to tour the place and solve whatever puzzles you can.
    The zoo is divided into three sections. The first is Aliens, representing some of my own original puzzle types. The second is Mutants, showcasing some of my variations on familiar Nikoli types. The final is Hybrids, in which each type is a combination of two types, both selected among either Nikoli types or my own original ones. There are four different types of puzzles in each section, for twelve types total.
    For each puzzle type in the Alien and Mutant sections, the zoo has two specimens. The first is a baby version, which should prove fairly docile. The second is an adult version. Caution is advised when viewing the adults, as they can be quite aggressive. However, the adult is worth significantly more if successfully solved. The Hybrid section has only adult specimens, with no babies. This means there are 20 puzzles total in the test.
