All three of these will quiz you on flags tonight, free. The question is what you want out of it: a huge trivia library, a structured map drill, or flags you still know in October.
We build FlagTutor, so we have a horse in this race. Below is the comparison we would want if we were the ones choosing.
The short answer
Sporcle, for variety
Seterra, for the classic drill
FlagTutor, for durable recall
What each one is actually for
Sporcle is a trivia platform. Its geography section is a slice of a much larger quiz universe, and the community model is its superpower: if you can imagine a quiz, someone has already built it. The trade-off is that a one-off quiz is a test, not a curriculum. Your result is a score, and improving it means replaying the same list until the order burns in, which is memorising the quiz rather than the flags.
Seterra is a drill book. Methodical and free, with a progressive continent-by-continent structure that genuinely builds foundations. Since the acquisition it runs on GeoGuessr’s accounts and interface. Its model is repetition by volume: you repeat the exercise you choose, when you choose. The software keeps score. The scheduling is on you.
FlagTutor is a memory engine with quizzes on top. Every miss feeds a review queue, called Weak Spots, scheduled by an SM-2 spaced-repetition algorithm: the flag you confused comes back right before you would forget it again, at widening intervals as you get it right. Two difficulty modes, multiple choice to learn the shapes and type-in to prove you know them cold. It is also the only one of the three with live head-to-head, where you race a friend on the same quiz in real time or send an async challenge link.
Where FlagTutor does not win
Fair is fair.
Library breadth
Classroom orthodoxy
Zero-friction anonymity
The retention difference, concretely
Say you confuse Senegal and Mali on Monday. On Sporcle, that miss vanishes when the page closes. On Seterra, it waits until you choose to rerun West Africa. Here, Tuesday’s queue opens with Senegal and Mali side by side, again on Thursday, again next week, until the pair is boring to you. Same minute of effort, different destination.
That is the whole pitch. Not a bigger library, a schedule.
Pick your tool
Trivia night with infinite variety: Sporcle. A free structured map drill, especially for a classroom: Seterra, via GeoGuessr. Flags and capitals that survive past the weekend, with a friend to race: start with the world flags quiz, free, and let Weak Spots do the scheduling.

Practice this
The method is the same whichever tool you use. Here it runs itself: every miss is logged and rescheduled, so the queue below fills with your own problem items rather than everyone’s.
