Compare your IQ (Intelligence Quotient) and logic with other players and countries!
⚔️ Real-Time Duels Challenge another player in a live duel and find the logic in the presented series. To ensure fairness, you and your opponent solve the exact same questions.
⏱️ Speed and Accuracy Each player has a health/time bar. The first player whose bar runs out (or who quits the duel) loses. Every correct answer gains you time, but be careful: wrong answers cost you precious seconds!
🏆 Rankings and Trophies At the end of a match, trophies are awarded to the winner (and lost by the loser) based on an advanced rating system. Multiple rankings are available: Individual and by Country. By playing for your own rank, you are also fighting for your country! Who will be the best? Which country will be the smartest?
📅 Seasons and Rewards Rankings are valid for specific "seasons" and reset at the beginning of each month. Every month, the top 1000 players and top 100 countries receive an exclusive reward: collectible "Brains".
🧠 Training and Progress
Friendly Mode: Invite a friend to train (does not count for rankings).
Full Tutorial: Learn how each sequence works with clear examples.
Achievements: Unlock badges by reaching ambitious goals.
Note: A connection to Google Play Games is required for real-time multiplayer.
