Big Brain

Think fast. Run faster. Multiply everything.

Big Brain is the addictive endless math runner where your brain is your only weapon. Sprint down the track, blast through math gates, and watch your number explode from a tiny 1 into a massive, unstoppable giant. But choose wrong and you'll shrink fast — pick the smart gate every time!

🧮 SOLVE ON THE RUN
Every gate is a split-second decision: + add, − subtract, × multiply, or ÷ divide. Your number is your health AND your power — the bigger it gets, the further you go. Keep it above zero or your run is over!

🏃 ENDLESS ACTION
No levels. No loading. No limits. The road never ends and the challenge never stops. Every run is different, every run gets faster, and every run pushes you to beat your best score.

💥 SMASH THROUGH BLOCKERS
Grow your number big enough and plow straight through the obstacles in your path. Dodge, weave, and steer with simple one-finger swipe controls that anyone can pick up in seconds.

📈 RAMPING DIFFICULTY
The further you run, the faster you go and the trickier the gates become. Speed builds, obstacles multiply, and only the sharpest brains survive to the end.

💰 COLLECT & COMPETE
Grab coins, chase currency gates, and climb toward a new high score. Can you build the biggest number of all?
