The Doodle Challenge™
Think Outside the Lines
The Doodle Challenge™ (TDC), is an award-winning Playtool™ powered by a growing proprietary library of original Doodle Marks™, designed to get people seeing, thinking, creating and connecting in new ways.
Play for a few minutes or keep going. On your own or with other people. At five, at forty five, at ninety five. It builds core cognitive skills everybody uses: perspective building, problem solving, creative thinking, focus and communication.
No art skills required, because it's not about what you draw. It's about what you see.
TDC has been used by schools, families, therapists, Fortune 500 teams, and wellness programs across the globe.
Good For Your Brain Wrinkles.
Laughter is the best medicine, but The Doodle Challenge™ is not just fun, it has numerous health benefits, too! Just 15 minutes of play helps practice core cognitive skills that fight:
Making it Look Easy.
Nothing on the card is accidental. Not the mark, not where it sits, not how much of the page is untouched. Every Doodle Mark™ is an original, heavily researched and created glyph using PLAYSTRUCK’s proprietary method, drawing from art and design theory, psychology, cognitive anthropology, the science of play, and years of real-world testing.
Marks are made, tested with real people, and reworked when they don’t do what they were built to do. Only the ones that qualify make it into your deck.
It's Not About What You Draw.
It's What You See That Matters.
Easy To Pick Up.
Surprising In Practice.
Before we even had a chance to start measuring, people let us know that some interesting things were happening: less stress, a boost in creativity, better conversations, more connection, and new ways of seeing things.
Researched, Tested.
Research, expert collaboration, and years of real-world use continue to help us understand what people are experiencing, and shape what marks we build next.

The Science of The Doodle Challenge™
The Doodle Challenge™ is more than just visual play. It’s a research-informed system built to shift how people think and feel.
In a pilot study, just 15 minutes of gameplay led to a 35% reduction in reported stress levels among adults. That’s the power of structured, low-pressure play: it helps quiet the nervous system while waking up the mind. Each deck is built with intention, developmentally appropriate, deeply researched, and field-tested with students, therapists, and teams. The result? A fun, simple tool with serious impact.

Fun but can have some real meaning. I like the fact that it makes you think fast - kinda makes you feel instead of think so much. Fun.

THE DOODLE CHALLENGE X LULU LEMON
Lululemon proudly partnered with The Doodle Challenge™ (TDC) to host a live creative experience at their Manhattan flagship store, blending movement, mindfulness, and play. The event drew 200+ participants (both in-person and digital) for an evening of spontaneous doodling, joyful gameplay, and unexpected surprises, including a guest appearance by legendary party crasher “Shaggy” (Steve Kaplan).
To honor Lululemon’s yoga roots, TDC created 6 exclusive Doodle Cards inspired by iconic yoga poses. These special edition cards invited players to embody movement while visually expressing emotion and energy. The cards were only available during the event, used in gameplay and featured in the event’s finale.
