How it works
From sign-in to a live game in three steps
- 1
Make a class
Sign in with Google or an email code and name your class. You get a 6-letter class code.
- 2
Put the code on the board

- 3
Play and see results
Host a live game, start a race, or set a quiz. Scores, who hasn't played and the hardest flags fill in as they go.
Ways to play
One class, three ways to play
Live game
Each flag flashes on the classroom screen after a 3, 2, 1 countdown. Students race to answer on their own devices, with a leaderboard after every flag and a podium at the end.
Race board
Students play when they're ready while the board shows everyone racing to the finish. Good for mixed-ability classes and fast finishers.
Set a quiz
Pick a region, a difficulty and 10 to 30 flags. Every student gets the same flags, and their results land in your class as they finish.
Results
See who knows it, and what to teach next
Every quiz shows each student's score, who hasn't played yet, and the flags the class found hardest, so you know what to go over tomorrow. A class leaderboard keeps the running total across every quiz.
- Easy, Normal and Expert, with look-alike flags on Expert
- Let a student rejoin on a new device and keep their scores
- Download every result as a spreadsheet with Teacher Pro

RomaniaWhy it works
Built on how memory works
Students who are tested on something remember far more a week later than students who re-read it. Flag Flash is built around that: quick recall, spaced out over weeks.
Flags flash, then they're gone
Students pull each answer from memory instead of staring until they work it out. That effort is what makes it stick.
A review every Monday
The 10 flags your class missed most in the last four weeks come back as homework, set for you.
See what's sticking
Your class page counts the flags students learned after a miss, and how many they still knew a week later.
Compared with other tools
The world, ready to play as a class
Quiz games like Kahoot and Blooket are great at running a class, but you have to bring the geography. Geography sites like Seterra have the content, but were built for one player. Flag Flash is both.

Questions
Before you start
Do students need accounts or email addresses?
No. Students go to school.flagflash.com/join, type the class code and their first name, and they're in. There's nothing to install and no email address to collect.
What devices does it work on?
Any phone, tablet, Chromebook or laptop with a web browser. The live game and race board go on the classroom screen through your normal browser.
What do you store about students?
Only the first name a student types and their quiz results. You can remove a student or delete the whole class at any time, and nothing is shown publicly.
What happens when I reach the Free limits?
Nothing you've made disappears. On Free you can have 3 classes of up to 40 students; to add more, upgrade to Teacher Pro from your classroom page, or ask your school about a license.
Can my school pay by invoice or purchase order?
Yes. School and District licenses are paid by invoice or PO. Ask for a quote below and we'll send it within one working day, with our data processing agreement and supplier details.
Can I cancel Teacher Pro?
Yes, any time from Manage billing on your classroom page. You keep Pro until the end of the period you paid for, then go back to Free with all your classes intact.
I already use Flag Flash with my class. Do I have to pay?
No. If you made a class before 1 November 2026, you keep everything free until 31 July 2027.
