How it works
Compare
Pick a fighter, choose Compare, and trust your numbers. The faster and cleaner you solve, the harder you hit — from gentle early grades all the way to Olympic-level challenges.
Two numbers stand face to face. Your job is easy: point at the bigger one.
Imagine two plates of cookies — one has 3 cookies, the other has 7. Which plate would you grab? The 7, of course. That plate is bigger, so 7 is the bigger number.
Tap the number that's worth more. There's no adding here — just trust your eyes.
