This week marks the debut of our new puzzlemaster: Murat Can Tonta!

Murat has been one of our more prolific guest contributors, and also sent many phenomenal puzzles for The Art of Puzzles 2, coming next year. It is a pleasure to welcome Murat to the GMPuzzles team.

Murat’s debut week will feature a mix of logic puzzle styles, as well as word logic variations. Will there also be another hidden puzzle that makes you look across the site for some kind of link, or just a full week of very fun puzzles? Come back over the next seven days to see what unfolds.

Last week’s mix of puzzles can be found in this PDF.

There will be no new puzzles this week, but next week we’ll be welcoming another puzzlemaster to the ranks as we close out 2015.
