The question for quiz day 7 was:
How many islands do you need to complete to get at least 1 Ninja?
The answer was given as 12, but I’m the only one who replied with 13.
You still aren’t sure of a ninja after island 12, there is still a ship before you get a ninja. The question was only about islands, so in order to be 100% sure, 13 islands need to be completed (13 doesn’t even have to be “completed” but that’s not the question).
