Triad

How to play

• Each card has 4 features (color, number, shading and shape), and each feature has 3 different possibilities:
• Color: red, green or blue;
• Number: 1, 2 or 3;
• Shading: outlined, striped or solid;
• Shape: square, circle or triangle.
• Click on a card (white rectangle) to select it. Click twice to unselect;
• Select 3 cards to create triads where each feature is either the same between all 3 cards or is different on each card;
• After selecting 3 cards, the game will shows if the triad is valid or invalid by changing the color of the words "color", "number", "shading" and "shape":
• GREEN shows that either all the features are identical or all the features are distinct;
• RED shows that neither all the features are identical nor all the features are distinct.
• The game ends when you find the asked number of triads, which is 4 for the basic puzzles and 6 for the advanced ones.
