About Quizzoo

What Quizzoo is

Quizzoo is a quiz game that runs in a web browser. There is nothing to install and no account to make. Pick a topic or an age and the first question is on screen in seconds. Play Quizzoo.

The game has 12 topics: flags of the world, capital cities, the world map, maths, biology, space, dinosaurs, history, landmarks, the elements, spelling, and how to say hello in other languages. It has a quiz of its own for each age from 5 to 13, a Daily Challenge, and a party mode in which two to six players share one device.

Beside the game there are pages of questions with their answers, one for each age and one for each topic, to read out or to print. The longest is Children's quiz questions and answers.

Who it is for

Children aged 5 to 14 who like finding things out, and the parents, grandparents, teachers and club leaders who quiz them. The quizzes for ages 5 to 7 use short questions. Most have answers to pick from, and some sums are answered on a number pad, so nobody has to type a word. The quizzes for the oldest ask things that plenty of grown-ups find hard.

A teacher can use it without setting anything up. There are no class codes and no pupil accounts. The game asks a player for a name to play under and, if they like, their age. Both stay on the device.

How a question is made

Most Quizzoo questions are not typed out one by one. The game holds facts, and the part of the game called the engine turns those facts into questions each time someone plays.

The facts are kept as lists: 195 countries with their flags and capitals, 41 chemical elements, 72 landmarks, 72 dated events in history, 25 ways to say hello, the 8 planets, 38 dinosaurs, 33 other animals, and 195 words from the spelling lists in the national curriculum in England.

To ask a question the engine picks one fact, chooses a way of asking that suits the player's age, and picks wrong answers that are believable. A flag question for a five year old offers only famous countries. The same flag for a twelve year old can sit beside its look-alikes.

Maths questions are worked out, not looked up. The engine makes the sum, works out the answer, and offers as wrong answers the slips a child might really make.

Some lines are written out one by one: the true or false statements, the history myths and the line of explanation under an answer. They are kept as lists as well, and they go through the same checks.

The question pages on this site are printed from the same engine. They are built again whenever the game changes, so a page shows the answers the game itself gives.

How the answers are checked

A wrong answer taught to a child is the worst mistake a quiz can make. So each of the 12 topics has been through three rounds of checking.

The latest round was in October 2026. Two separate checks went through each topic and listed anything that looked wrong, unclear or out of date. Each point was then checked again against fresh sources. A correction went in only after one more check had tried to prove it wrong.

The sources named in the check logs include Encyclopaedia Britannica, the CIA World Factbook, the United Nations, UNESCO and the Merriam-Webster dictionary. The spelling words come from the lists in the national curriculum in England.

A log is kept for every topic. It lists each point that was raised, what was changed, and what was left alone because the game was right as it stood. The log for capital cities, for example, lists 22 points: 17 led to a change, 3 turned out to be right already, and 2 were judgement calls kept for a person to decide.

The engine has automatic tests too. They run before every release, and they check that a question has exactly one right answer, that no choice appears twice, and that a round does not ask about the same thing twice.

Pictures are checked as well. A picture beside a question must never give the answer away.

No check catches everything. If you spot a mistake, please ask a grown-up to say so on the Quizzoo Facebook page. The round Facebook button at the foot of this page leads there.

What is saved on your device

Quizzoo has no accounts. There is no sign-up, no email address and no password. A player is a name, a character, an age if you pick one, and their progress.

All of that is saved in your own web browser, on the device you play on. Up to six players can share one device. The names, ages and answers typed into Quizzoo are not sent anywhere.

Because progress lives in the browser, clearing the browser's data clears Quizzoo too. In the Grown-ups area of the game a grown-up can save every player's progress to a file, load it on another device, reset one player or remove everything.

Players cannot message anyone, and nobody can message them.

Like every website, the company that hosts Quizzoo sees a device's internet address when a page loads.

How visits are counted

Quizzoo would like to know which quizzes get played, so it uses Google Analytics to count visits. That uses cookies, so it only happens after a grown-up says yes to the question at the bottom of the screen. Until someone says yes, nothing is loaded from Google.

What Quizzoo counts: visits, which page or screen was opened, which quizzes were started and finished, and how many stars a finished quiz earned. A player's name, a player's age, an answer or anything typed is never sent. As on any site that uses it, Google Analytics also records general details of a visit, such as the kind of device and the country. Its advertising features are switched off.

To change the choice, press Cookie choices at the foot of this page or of any question page. In the game, open the Grown-ups area and look under Privacy. Saying no stops the counting and removes the Analytics cookies.

What it costs

Quizzoo is free to play. To pay for its upkeep it may one day carry adverts suitable for children, or offer optional plans for families or schools.
