23 free brain games to help your child practice logical thinking, planning and focus while having fun. From mini sudoku to lights out, shape analogies to connect four, every game is built from short rounds — no sign-up, no download and no app to install, and it opens in seconds on a phone, tablet or computer.
Classic logic puzzles where you think about each move before you make it: switch off the lights, fill the sudoku, connect the pipes, push the boxes.
Turn-based moves against an opponent, tower defence and step-by-step coding — games that teach planning a few moves ahead.
Find the link between shapes, guess what comes next, spot the odd one out, balance the scale — games that build abstract thinking.
Beat-the-clock arithmetic, number sequence recall and true-or-false knowledge quizzes.
Most games are designed for ages 5 to 12. Which One Is Different? and What's Next? suit preschoolers, while Mini Sudoku, Lights Out and Tower Defender work best for children aged 7 and up who are confident with reading and numbers.
Puzzle games usually focus on completing a picture or a grid. Brain games add other thinking skills on top, such as strategy, pattern recognition, sorting and quick arithmetic; some games appear in both categories.
All brain games are completely free. No account, email or download is needed; each game opens right in the browser and progress is stored only on your own device.
