Trio

Goal: Find as many trios as possible until the deck runs out.

What is a trio? Three cards where, for each of the four features, the values are either all the same or all different across the three cards. The four features are:

  • Count – one, two, or three shapes
  • Shape – diamond, oval, or triangle
  • Color – red, green, or purple
  • Fill – solid, striped, or outline

Example of a valid trio: all three cards show different shapes, but all in the same color, the same count, and the same fill. Each feature is either uniformly shared or uniformly different.

How to play: Click three cards. If they form a trio, they vanish and three replacement cards are dealt. If not, the cards briefly flash red and deselect. There’s no penalty for guessing.

Stuck? Click Hint to highlight a valid trio. If no trio is possible in the current layout, three more cards are added automatically.

Winning: The game ends when the deck is empty and no trios remain.
