Think of a valid answer fewer players will choose
You have six open prompts per mission. Answers that fewer people give tend to score higher, so choose an obscure example that still fits the question. The game accepts an English answer or a skip.
Choose a daily or practice run
Daily missions share the same prompts. Unlimited mode deals fresh questions, so use it to practice without spending your daily attempt. Review the mission log to see when a common answer cost you points.
