You and your opponent step into the arena as two rival brains, the crowd fills the stands, and 14 questions decide who walks out the winner. Every round puts one arithmetic problem on the board and four possible answers.

Addition, subtraction, multiplication, division — no calculators, no second guesses. The first brain to hit the correct answer takes the point and lands a punch that sends the other one reeling in a cloud of stars.

Guess wrong and you've handed your rival a free shot. Take too long and the 10-second timer runs out and nobody scores.

Whoever wins the most of the 14 questions wins the match. TWO WAYS TO PLAY • Quick Play — duel an AI opponent that learns your level.

It starts slow and sloppy for a new player and turns genuinely fast and accurate as you climb, so it never stops being a fight. • VS Online — real-time 1v1 against another live player.

Same questions, same clock, pure reaction speed. STAKE YOUR COINS Every match costs an entry fee, and the pot pays out on performance.

You bank coins for each question you win plus a bonus for taking the match, so a dominant round grows your balance and a sloppy one drains it. Run dry and you can top up with a rewarded video or a coin bundle.

CLIMB THE LADDER Wins pay 30 trophies, draws 10, losses cost you 15. Every 120 trophies is a new level, and your level drives everything — the bot's speed, its accuracy, and how big the numbers get.

Fifteen levels separate a warm-up from a real test. WIN STREAKS PAY Three wins in a row pays a bonus.

Five pays more. Seven, then ten, pay more again — and past ten the top bonus keeps landing.

A draw holds your streak; only a loss breaks it. COME BACK DAILY A seven-day login cycle pays out every day you show up, from 50 coins on day one to 500 on day seven.
