As organizers of WSPC26, we at Logic Masters India want to create an interactive atmosphere in the lead-up to the event. We are conducting a Puzzle Innovation Contest from 14th March to 15th April. Everyone is welcome to participate in it.
The Contest:
- The Puzzle Innovation Contest is being held with an aim to increase the pool of innovation for WSPC 2026, and also to recognize the best innovations and innovators. We are looking only for original ideas in puzzle types, and ideas of new variations in Sudoku, which have not been seen elsewhere to the best of the author's knowledge. Do only submit ideas that you have not seen before!
- Multiple submissions by the same author are allowed.
- Accepted submissions must not be used until end of WSPC26.
- Considering the themes of WSPC26 (Mahabharata and Ramayana), we encourage ideas centered on ancient Indian weapons.
How to participate:
- Send your idea to pic2026@logicmastersindia.com. All submissions must follow a fixed format: Send a pdf with the name/rules of the puzzle, a sample puzzle, and the solution to that sample puzzle. The deadline for submissions is 15th April.
- This forum topic will be regularly updated confirming submissions by authors. If a submission is rejected for being too close to an existing idea, we'll privately contact the author with reasoning.
- The organizers will be judging the submitted idea and puzzles.
- On the same date as the Instruction Booklet release of WSPC26, the ideas will be showcased on the WSPC website. LMI claims the right to publish the author's puzzles too along with due credits.
- Depending on the puzzle type submitted, the idea may be used in innovative rounds in WSC and WPC.
Judging criteria:
- Idea: This is about how interesting the innovation is. We will also consider that the type is not restrictive in terms of different logical implications and whether the puzzles can be built on in terms of variations. For example, Tapa/Sudoku/Fillomino were ideas with a lot of potential to build on. For Sudoku variations, only interest and restrictiveness will be considered in this section.
- Simplicity: The simpler the rules, the better.
- Puzzle: A quality puzzle goes a long way to best showcase your idea. Considerations include logical path and theme, in that order of priority.
Prizes:
- The three best innovations in each of Sudoku & Puzzles will receive special prizes at WSPC26 in Kolkata.
- Some ideas might be selected to be a part of the innovative rounds at the WSC and WPC respectively. The authors will be credited with the ideas in the Instruction booklet.
- While this is not a criteria for the contest, there are more chances of the idea being used in innovative rounds at the WSC and WPC if the idea is centered on ancient Indian weapons.
