About Kidorizon
Kidorizon is thinking-skills and AI-literacy practice for kids from Pre-K to Grade 12. Short, friendly activities help children spot patterns, reason step by step and check what they are told, including answers from AI.
What kids can do here
Brain Games
Picture Logic, Sudoku, Maze Run, Memory Flip, Mirror Mirror and many more, with difficulty that adjusts to each child.
Puzzles
The Daily Puzzle plus activities like Catch the AI, Think First, Fact or Fake and Logic Grids.
Reasoning practice
Short sets of verbal, number and picture reasoning questions for every grade, each with a clear explanation.
Learn
Bite-size strategy lessons with a worked example, so kids know how to approach a problem, not just the answer.
Worksheets and printables
Printable reasoning worksheets and activity sheets with separate answer keys, for the table or the car.
Gifted and reasoning test practice
Timed practice exams in the style of common gifted and reasoning tests, with original practice questions and a results report (Premium).
Everything is grouped into five grade bands, from Pre-K–K up to Grades 9–12, so the practice matches each child.
Why Kidorizon exists
Kids can get an answer to almost anything in seconds. We want them to think, not just memorize: to notice a pattern, explain a step, and catch it when something doesn't add up.
Feedback is gentle. Every answer comes with a short explanation, and after a couple of misses the questions ease back a little, so mistakes feel like part of learning rather than a failure.
Our Think First, Then Check routine builds one simple habit: answer first, then check, whether the answer came from a book, a friend or an AI.
How we use AI and technology
- Brain Games, Reasoning Practice and worksheet questions are generated fresh by Kidorizon, so practice keeps bringing new questions and retakes use fresh ones.
- Answers are checked on our server, and each child's level adjusts to how they are doing.
- The “AI answers” in Catch the AI are pretend answers with one deliberate mistake for kids to find. No chatbot talks to your child.
Our promises
- No ads. No ads of any kind and no advertising trackers.
- No upsells to kids. Plan and upgrade messages are for parents, not children.
- Children's privacy first. Built with COPPA in mind. Accounts are for parents only; a child profile is just a nickname and grade that a parent adds with permission. Guests are never saved.
- Parents stay in control. See, download or delete everything we keep, any time. Read our Children's Privacy Policy, Privacy Policy and Parents' rights.
