Trio Remix

The classic spot-the-set perception game. Every card combines four traits — count (1–3), colour, shape and shading — each with three options, for 81 unique cards. A trio is three cards where, for every trait, the three are either all the same or all different. Twelve cards sit on the table; find a trio fast and it clears as three fresh cards slide in. No trio showing? Three extra cards appear (the maths guarantees a trio always turns up). Hit the per-level target before the timer empties — the clock tightens each level. A pure, beautiful test of pattern recognitio
