As a program developed by the Gathering 4 Gardner Foundation, we encourage people of all ages to come together in the spirit of fun and curiosity to celebrate the things that delighted Martin Gardner—puzzles, games, math, magic and more!

Learn About Us
Celebration of Mind events bring people of all ages together to share and delight in playing with puzzles, games, math and magic. As Martin Gardner said, you can learn more when you’re in a state of entrancement and that’s our guiding principle.

Large and small, formal and informal, CoM events are happening around the world. We’ve seen puzzles on the patio, sleight of hand stage magic, recreational math in retirement homes and backyard bagel parties—look for a celebration you can join!
