Tap cards to select them. When 3 are selected, they are automatically validated.
Each card has 4 attributes: shape, color, count, and fill.
Find all valid Sets to complete the game! The faster you go, the higher your score.
Core Rule: All Same or All Different
A valid Set consists of 3 cards. For each attribute (shape, color, count, fill), all 3 cards must be either all the same or all different.
Check Every Attribute
If even one attribute has 2 cards the same and 1 different, it is NOT a valid Set. All 4 attributes must satisfy the rule.
Completed Example
Shape: circle, square, triangle — all different
Color: red, green, blue — all different
Count: 1, 2, 3 — all different
Fill: solid, striped, empty — all different
Tip
Compare one attribute at a time systematically to find valid Sets faster.
If you spot an attribute with 2 same and 1 different, eliminate that combination immediately.
Start by checking attributes that are all different — it narrows down candidates quickly.
PatternMatch is based on a pattern-matching game invented in 1974 by geneticist Marsha Falco while visualizing patterns in research data. It has been used as a cognitive science tool to measure abstract reasoning and visual pattern recognition abilities.
