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.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
