Touch Grass Bingo is a nature bingo card that you play outside. You open it, get a seasonal card (a red leaf, an acorn, moss, a feather, a mushroom…), and put your phone away. When you find something, you take one photo. An open-weight vision model running on your phone checks it and marks the square.
The center square is never free. It is "Touch grass": a photo of your hand on real grass.
The screen is the shortest part of the game: one glance at the card, then the phone goes in the pocket until you find something.
