The World Puzzle Federation is an international organization based in Amsterdam , which is dedicated to solving, creating and disseminating logical puzzles . The organization brings puzzle solvers from all over the world together for puzzle competitions. The World Puzzle Championship has been held annually since 1992, and the Sudoku World Championship since 2006 . The most successful participant in the puzzle world championships is Ulrich Voigt (Germany) with eleven titles, Thomas Snyder (USA), Jan Mrozowski (Poland) and Koto Morinishi (Japan) won the Sudoku world championship three times.
Since 2006, Germany has been represented in the World Puzzle Federation by the Logic Masters Deutschland eV association. Among other things, the association organizes the annual German puzzle and sudoku championships. Before that it was Bastei-Verlag .
Goals of the association
According to the website, the goals of the association are:
- Organize the World Puzzle Championship, Sudoku World Championship and other WPF events.
- To provide the means for international exchange on puzzle ideas.
- To encourage innovation in the field of puzzles.
- Maintain friendships among puzzle enthusiasts around the world.
World championships
The puzzle world championships have been held annually since 1992, in which a team of up to four candidates from each country can take part. The championship lasts 2 to 2½ days. The first two days consist of various rounds in which the participants sometimes have to solve puzzles individually, sometimes as a national team. Points are awarded for each correctly solved puzzle. These are accumulated and result in individual and team scores. At the end of the second day, or for several years at the beginning of the third, the playoffs take place, in which the best participants from the first two days decide the world champion among themselves. So far there is no fixed mode for this, each organizer can determine this himself. In the case of the team classification, there was a playoff for the first time in 2014. It is still open whether this will establish itself.
In addition to the world puzzles championships, there have also been Sudoku world championships since 2006, and since 2009 these have been held directly before the world puzzle championships in order to keep the organizational effort down.

From 1992 to 2005 the German member of the WPF was the puzzle editor of Bastei-Verlag . This was dissolved at the end of 2005 due to a merger of Gong and Bastei. Since 2006 the association Logic Masters Deutschland eV, which was founded in February 2006 on the premises of Bastei Verlag, has been the German member.
The association Logic Masters Deutschland eV annually organizes the German puzzle championship "Logic Masters" and the German Sudoku championship and since 2016 the German Youth Sudoku Championship. Occasionally other competitions are organized, such as the German optimization championship. He also runs a puzzle forum where interested parties can exchange ideas about puzzles and a PuzzleWiki in which types of puzzles are collected. In order to keep track of the types of puzzles, the members of the association have developed a taxonomy system analogous to that used in biology , which, however, is still incomplete and currently only covers the types of puzzles with which the association is primarily concerned. However, the system is designed in such a way that it can be expanded accordingly if required. The association also operates the puzzle portal, where those interested can post their own puzzles and solve other people's puzzles.
aims
According to the statutes, the goals of the association are to represent Germany in international puzzle competitions and to promote and disseminate logical and mathematical puzzles in sporting competitions.
German puzzle championship / Logic Masters
The German puzzle championships took place for the first time in 1994. With the exception of 2001, they have been carried out annually since then. They consist of two parts, a qualification (also 1st qualification, preliminary round), in which the participants have to solve puzzles at home, and a final (also 2nd qualification, final round), which takes place in a central location and to which only the The best participants in the qualification are invited, since 2006 also the World Cup team from the previous year, as well as occasionally additional participants who receive a wildcard from the club. Since 2004 the German puzzle championship has been called "Logic Masters".
The final round consists of about 7 different rounds in which the participants can collect points. The four best participants form the World Cup team. Since 2006 these participants have been competing in the final for the title of German Puzzle Master. The number of World Cup team and final participants to be determined can be reduced if people have already been placed in advance. As a rule, these are puzzle solvers who have shown particularly good performance in advance and who have created the puzzles for the final round.
There have been numerous changes over time. Up until 2006 it was common to have to solve optimization puzzles in the qualification where not just any, usually unambiguous, solution was sought, but the best possible solution had to be selected from a multitude of possible solutions. There was always considerable criticism of this, as a different skill was required for qualification than for the final. These optimization puzzles became necessary because the participants who received their documents by post had too much time and could therefore solve all the other puzzles and thus could no longer distinguish between the performance of the individual participants.
In 2007 the old system with the optimization puzzles was replaced by an online qualification in which the participants only have a limited time, usually 2½ hours. This enabled optimization puzzles to be avoided. However, the new system is still vulnerable to fraud. In practice, however, there have been very few abnormalities so far. Fraudsters would be noticed anyway, especially in the final round.
A Friedbert Schiemann appeared in 2001 as a guest on the ZDF quiz show CASH and was introduced there as a former German puzzle master. Inquiries revealed that there was a German puzzle championship organized by Klampt Verlag in 1968 and 1969.

| 2001 | The 2001 championship was canceled. A letter from the organizer of the previous year to the participants of the World Cup team of the previous year shows that the team had been transferred and that he was informed that he was no longer responsible for the championship. The new employee of Bastei Verlag, who now held the post of old organizer, was informed that the old organizer would continue to take care of it. The mix-up was probably due to the fact that both had different bosses and they hadn't discussed each other. When this problem became known, there was not enough time to organize another championship. However, it was still possible to re-register the old World Cup team for the 2001 World Cup. | ||||||

After some unsatisfactory considerations in which form the possible valuation error could be taken into account, it was finally decided to keep the original result. |
German Sudoku Championship
Since 2006, the German Sudoku Championship has consisted of an online qualification and a final round, in which, in addition to the online qualifiers, the previous year's World Cup team are also qualified. The club can also give guests a wildcard at its own discretion.

| The first German Sudoku Championship was proclaimed and carried out without authorization by the Berliner Zeitung . The club subsequently recognized this championship. During the championship only standard sudoku were to be solved. A system was used in which two participants always competed against each other and the faster one or the one who entered more digits after a certain time progressed. | |||||
| 2006 | Hamburg | Michael Ley | Michael Smit | Roland Iago | Bernhard Seckinger, Immanuel Halupczok |
| There were problems with the qualification as it was held on the Stern (magazine) server and the technician responsible was on vacation. This had to be repeated a week later. The selection of puzzles for the final round was criticized by some participants, as some of them were very far from the standard Sudoku. As a result, the association decided to only use variants in which the grid is made up of 9x9 fields and the areas are square. There is also criticism of this convention because it excludes Chaosudoku . However, it was retained until 2015. | |||||

| 2012 | Dusseldorf | Florian Kirch | Martin Merker | Michael Smit | Stefan Heine, Richard Stolk |
| There was some criticism of the final puzzle, which only a single participant could solve in about an hour. Together with a rather unfavorable second criterion, in which correct digits were counted in the diagram, this meant that Michael Ley, who had clearly moved up from 3rd place before the final, did not join the World Cup team. | |||||

German Youth Sudoku Championship
In 2016 there was a German Youth Sudoku Championship for the first time. The qualification took place in schools and other selected institutions. The final round took place at the same time as the German Sudoku Championship. Since 2017 there has been an online qualification in addition to qualifications at schools.

German optimization championship
The German optimization championship took place from 2007 to 2010, but was then discontinued because it was very strenuous and time-consuming for both the organizers and the participants. All optimization championships were held online.

Club magazine
Since 2006, the association has published a club magazine to its members, which was initially called "memorial paper". After legal disputes with the Federal Association for Memory Training, this name had to be given up. The magazine was then renamed "Not even diagonally". Initially, the magazine appeared three to four times a year. Since around 2012 only one copy has been printed each year.
Puzzle portal
The puzzle portal was created to counter the criticism that the club's activities are almost exclusively dedicated to solving for a while. There everyone can set their own puzzles and solve the puzzles of the others. In other words, the puzzle portal is more dedicated to popular than top-class sport. The first puzzle was dropped on November 1st, 2008. It is an ABCtje by Richard Stolk with the names of puzzlers who were active at the time. Since then, almost 3000 puzzles by over 100 authors have been submitted (as of July 2, 2016).
All puzzles have a short solution code that can be entered to check the solution. In addition, once you have solved the puzzle, you can judge its difficulty and its beauty. In the course of time the scale for the level of difficulty has shifted further, so that beginners now find puzzles with only 2 stars to be very difficult.
