7 brain games: trivia, math, memory, word puzzles & reactions. Duel AI offline!
BrainDuel is a brain game that challenges you to outsmart an AI opponent across 7 skill-based mini-games. Trivia, word scramble, math speed, memory, reaction time, pattern recognition, and emoji puzzles — all in one offline game that works anywhere. Each match is a best-of-5 duel. Win more rounds than the AI to earn trophies and climb the ranks. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎮 7 MINI-GAMES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ Trivia Quiz Answer multiple-choice questions across dozens of categories — science, history, geography, pop culture, and more. A new question every round. ▸ Word Scramble Rearrange jumbled letters to spell the hidden word before the clock runs out. Short words are fast. Long ones will make you sweat. ▸ Math Speed Solve arithmetic problems faster than the AI. Addition, subtraction, multiplication, and multi-step expressions. Think fast. ▸ Memory Grid A pattern of cells lights up — memorize it. Then it disappears. Tap the cells you remember. Your recall vs the AI's. ▸ Reaction Test Wait for the signal. Then tap the instant it fires. Milliseconds separate a win from a loss. ▸ Pattern Match Scan a grid of shapes and find the one that doesn't belong. Color, shape, size, rotation — look carefully. ▸ Emoji Decode A sequence of emoji represents a word or phrase. Decode it before time runs out. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🏆 RANKING SYSTEM ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Every duel affects your trophy count. Win and climb. Lose and drop. Work your way through Bronze, Silver, Gold, Platinum, Diamond, Master, and Legend. The AI adapts — tougher opponents wait at higher ranks. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📅 DAILY CHALLENGE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ A new challenge drops every morning. Complete it to build your daily streak. Miss a day and the streak resets. Short, focused, and a different set of mini-games each time. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📊 STATS TRACKING ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ See your win rate, current and longest streaks, fastest reaction time ever recorded, total correct answers, and your performance broken down by each mini-game type. Know where your brain is sharp and where it needs work. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎯 PRACTICE MODE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Pick any of the 7 mini-games and practice with no rank on the line. Build speed and accuracy in a specific game type before bringing it into a real duel. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💡 HINT SYSTEM ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Each round gives you one chance to ask for help: ▸ Word Scramble — reveals letters one at a time (up to 3) ▸ Trivia — eliminates one wrong answer option ▸ Math — reveals the sign and parity of the answer ▸ Memory — briefly re-shows the pattern ▸ Pattern Match — tells you which property makes the odd item different ▸ Emoji Decode — reveals the first letters of the answer ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔋 FULLY OFFLINE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Every question, puzzle, and challenge is stored on your device.
