How to play
Turn over two cards. Match a colored object with its black silhouette, shown from the same angle. Choose 4, 6 or 8 pairs from 149 everyday shapes. Different cards stay visible until you choose Turn cards over; no timer. Show a pair completes one pair and counts it as help in the result. Undo restores the previous step. Daily set uses the same UTC date and pair count; progress stays in this browser.
