How to play

Compare the black silhouette with the colored objects. All choices use the same camera angle and fit inside their frame; the outline is the clue. Choose 3, 4 or 6 objects per round. Ten rounds, no timer. Hint fades some different shapes and removes the first-try point. Wrong choices stay marked so you can try again. Daily set uses the same UTC date and choice count; progress stays in this browser.
