Start from the weirdest emoji on the board — the one that could only plausibly belong to a single group — and build outward. Treat any grouping that feels instantly obvious as a trap. And before you submit a fourth card, re-check the three you already locked: the classic hard-mode failure is a group that is 3/4 correct with one borrowed member.
