Traps & near-misses
- “South Korea vs North Korea” — type the less-common South first only if the prompt allows either Korea.
- São Tomé and Príncipe — the accents matter in close spellings.
How this helps in the dive
S-list prompts are the rarest-letter jackpots: Spain and Sweden are free for everyone, while São Tomé, Suriname and the -ia Pacific states out-score them tenfold.
