Traps & near-misses
- Fiji, Samoa and Tonga are all valid — players type Fiji and stop.
- Iceland is an island country with no indigenous name rivals — but many forget it.
- Not every beach destination is a state: Puerto Rico and Bali are not valid answers.
How this helps in the dive
Island prompts look easy and then stall hard. Japan, Cuba and the UK get typed instantly; the Pacific micro-states are the deepest valid answers on the whole board — a handful of them sit in our top rarity band at maximum points.
