Are you creative , do you have a good imagination and are you able to make solvable sudoku variants ?
Whether you think that you are the right person, please contact Admin via Messages, or via email info@sudokucup.com (eventually as a comment of this news).
It will be pleasure for us to make public interesting first fruits of new authors and puzzles created by experienced authors, as well.
The only thing I'd like to ask you for is uniqueness of puzzles, tasks and of solutions, and marked lines or columns that will be needed to send as the result.
Regarding difficulty, ideal puzzles are those which can be solved in at least 6-8 minutes by very good players (there are some world champions playing here!).
