01 / THE REFERENCE
AN IMAGINARY NATURALIST’S PUZZLE
Under the cap,
a little universe.
Read the rings. Find the missing wedge. Rebuild twelve curious spore prints, one impression at a time.

A print is a fingerprint.
Match the reference on the left using the four tools. Count the main gills, find where each gill forks, measure the empty wedge, then turn it into place. Press Take impression to check your work. A clue reveals one tool; undo steps back. There is no time limit.
Tab reaches every tool; use arrow keys in the menus. Enter takes an impression, Z undoes a change. Completed prints stay in this browser.
02 / YOUR IMPRESSION0 impressions
Look closely. The empty space matters, too.
