❓ Frequently Asked Questions
What is Smart Kid IQ?
Smart Kid IQ is a free online brain quiz and games platform designed for children aged 6 to 14. It features 971 educational questions covering maths, science, logic, riddles, spatial reasoning, geography, and more — plus five free brain games including Tic Tac Toe, 9×9 Sudoku, Word Find, Memory Match, and Maths Blast.
Is Smart Kid IQ free to use?
Yes — completely free! There is no subscription, no sign-up, no login, and no download required. Simply open the website on any phone, tablet, or computer and start playing immediately. Every quiz, every game, every feature is 100% free.
What age group is the quiz designed for?
The quiz is designed for children aged 6 to 14 years old. Before the quiz begins, you can select your age group (6–8, 9–11, or 12–14) and the questions are matched to the right level of difficulty. Younger children get more straightforward questions, while older children face genuinely challenging brain-teasers.
How is the IQ score calculated?
At the end of the 20-question quiz, your score is converted into an estimated IQ score ranging from 70 (just starting out) to 145 (ultimate genius). This is an educational, motivational score — not a certified clinical IQ assessment. It is designed to be encouraging and to improve as children practise more. The seven IQ levels are: Just Starting (70–79), Good Thinker (80–89), Smart Cookie (90–99), Sharp Mind (100–109), Super Brain (110–119), Mega Genius (120–134), and Ultimate Genius (135–145).
What topics are covered in the IQ quiz?
The Smart IQ Quiz covers 11 different topic areas: Logical Reasoning, Number Patterns, Maths Problems, Science Facts, Riddles, Verbal Reasoning, Spatial Thinking, Word Play, Memory Challenges, Creative Thinking, and General Knowledge. The World Capitals quiz mode covers all 195 countries and their capital cities — a great geography revision tool!
