This is a collection of logical riddles. The solutions to these are meant to be purely logical; no special or clever "tricks" are required. The questions are self-contained and no additional knowledge is therefore needed (of course familiarity with logical thinking, as in mathematics or computer science, can be helpful).

You are more than welcome to add new riddles to the collection. To avoid any ambiguities, make sure to write the questions in a clear and self-contained way. Also, make sure you follow the conventions:
- Use Markdown syntax with a limit of maximum 80 characters per line.
- Give the riddle a short and concise title
- Save the question as a filename with only one word in the format
WORD.md. The solution should be saved asWORD_solution.md. - Link to the solution file in the question file, and vice versa.
Please study the files for examples on how to follow these conventions correctly.
