Frequently asked questions

Is everything on Cerebite really free?
Yes — every tool, game and printable is free with no premium tier, no locked levels and no time limits. The site is supported by ads, which is what keeps it free for everyone.
Do I need an account or an app?
No. Everything runs directly in your browser on phones, tablets and computers — nothing to install and no sign-up. Your preferences and best scores are kept locally on your own device.
What languages is the site available in?
The whole site — every tool, instruction and FAQ — is fully available in English, Korean and Spanish. Use the language switcher in the header; your choice is remembered on your next visit.
How do the leaderboards work?
Several games have live worldwide leaderboards. After a good run you can submit your score with a nickname — no account needed — and see where you rank against other players. Scores you don't submit stay only on your device.
Which tool should I try first?
Depends on your mood: the reaction time and CPS tests give instant fun in under a minute, sudoku and minesweeper suit a longer break, the flag and capital quizzes are great for learning, and the printables section has mazes and coloring pages ready for offline use.
