Michelle Kasper launched the Euro Jigsaw Jam virtual competition series within four months of having her passion for speed puzzling ignited by a YouTube video, despite never seeing an online competition herself.

In this episode of Piece Talks, I sit down with Michaela Keener. She takes us back to the early days of the modern competitive puzzling era, from the excitement of the first Duluth Derby to how the pandemic fueled the rise of "puzzlegram" and the unique world of puzzle influencer culture. Michaela shares her personal journey, including how the pressure of early influencer status and a documentary almost led her to step away from the sport. She talks about the about the pivotal moment at the 2023 NE Regionals, where she began her transformation from a performance-driven mindset to a growth mindset, a philosophy she applied during the intense 2023 Worlds Individuals Finals. We also delve into her unique practice methods, from mastering the art of calming and refocusing mid-puzzle to training in public spaces to conquer distractions. It’s an inspiring story of resilience and growth!

What makes a great speed puzzling image? Nathanael Mortensen, illustrator of five Ravensburger puzzles—including two unveiled at US Nationals—helps pull back the curtain on the art of puzzle design. We explore how he got into digital painting, what goes into crafting an engaging puzzle, and whether the artist or publisher shapes the final concept. Plus, what’s it like watching your artwork get dumped onto a table in pieces?

You may know that Chiara Dellantonio is a world-class speed puzzler who has finished 11th or higher in the individuals at every one of the last three years at the World Championships.

Twin sisters Jeanne and Cathy Roiter had been quietly kicking around the competitive jigsaw scene for a couple of decades until they won the first US Nationals Pairs competition by over 6 minutes in 2022.

A competitive puzzler since 1999, she is a member of the iconic puzzling team Wicker Kittens (and a standout personality in the movie of the same name), was a founding member of the USA JPA, and is currently Vice President of the World Jigsaw Puzzle Federation. And if none of that seems familiar, she announces the live streams at both the US Nationals and Worlds competitions.
