Put each card into one of the four piles.

A card can go with a pile by its color, its shape, or how many shapes it has. The rule for matching can change while you play.

After each pick, the screen tells you if you were right, and then a new card shows up. You can tap, click, or press the number keys 1 to 4.

  1. Look at the card in the middle of the screen.
  2. Pick the pile where you think the card goes.
  3. Watch what the screen tells you to figure out the rule.
One of the rules in this game uses color. If colors are hard for you to tell apart, or your screen is dim or has a color tint, the game can be harder to play.
