Best second guess after a wrong eye clue
Eye color is often a tie-breaker clue, not the main sorting tool. If your first guess misses on eyes, the best response is usually to strengthen your year and series read instead of chasing another eye-color test immediately.
Treat eye misses as low-priority noise early
A wrong eye clue on turn one rarely tells you enough by itself. Unless the answer pool is already very small, you should still use your second guess to test broader structure like era, genre, and franchise density.
Choose a guess that changes multiple tiles
The best second guess after a wrong eye clue usually changes hair color, year bracket, and likely series at the same time. That creates a cleaner information jump than trying to test only one alternative eye color.
Save rare eye groups for later
Rare eye-color groups become powerful when the roster is already narrowed. Early on, they are better used as study references than direct follow-up guesses unless another clue is already pointing there.
