Tríos Rules

• Each card has 3 attributes (Basic) or 4 attributes (Medium/Advanced): number, colour, shape, and texture.
• Each attribute takes one of 3 values.
• A Trio is a set of 3 cards where, for each attribute, the three values are either all the same or all different.
• Tap a card to select it; tap again to deselect it.
• Once you select 3 cards they are submitted automatically.
• Correct trio: +3 points. Wrong trio: −1 point.
• If no one finds a Trio after a while, a new card is added to the board.
• The game ends when the deck is empty and there are no more Trios on the board.
• The player with the most points wins.
