Partiti is a puzzle created by Thinh Van Duc Lai, a Vietnamese puzzle enthusiast most of whose puzzles involve mathematics in some form. His work has been featured in The New York Times, see here. Partiti puzzles appeared on Mathematics Magazine throughout 2018.
Brittany Shelton and I coauthored a short piece introducing the puzzle to the Magazine readers at the invitation of Michael Jones, the magazine editor and a colleague at Mathematical Reviews. It is titled Of puzzles and partitions. Introducing Partiti, and can be found on the arXiv or through my papers page.
