The classroom game where knowledge is power.
Every right answer becomes energy. Students spend it to claim land, build towers and storm castles on one shared map — so the class wins by knowing more and thinking smarter, not by luck.

Brains ON in three steps
No student accounts. No installs. Works on Chromebooks, tablets and phones.
Host on the big screen
Pick a question set or let AI draft one for your lesson, then show the game code on your projector.
Students join with a code
They type the code and a nickname on any device. Late arrivals and dropped Wi-Fi rejoin right where they left off.
Answer, earn, outsmart
Correct answers power every move. A comeback is always possible — through strategy, not chance.
Three ways to play
Same question set, three very different classes.
Kingdoms
Claim land, build towers and storm rival castles on a shared map. Big classes play in teams of about four.
Brain Race
Every right answer speeds up your team's racer. Draft behind a rival, overtake, and cross the line together.
Class vs Boss
The whole class teams up to defeat a dragon. Streaks land critical hits; everyone wins or loses together.
Built for real classrooms
What teachers keep asking for in classroom game reviews.
Fair, not random
Knowledge and strategy decide the winner. We test every mode with hundreds of simulated games so luck can't take over.
Kind to every learner
Accuracy stays private to the teacher. Team and co-op modes let students who are still learning share the podium.
No pay-to-win
Students never pay and never see ads. Rewards are earned by learning, not bought.
Privacy by design
Students play with a nickname only — no accounts, no emails, no photos.
Your language, your curriculum
English, Vietnamese, Spanish and Portuguese, with question sets written for local curricula.
Questions in minutes
Type your own or let AI draft a set; every AI answer key is double-checked before it reaches your class.
