How is the score calculated?

Each correct answer scores 10 points × your current streak multiplier (max ×8). Build a streak of correct answers to multiply your score.

What does the +2s bonus do?

Every correct answer adds 2 seconds to the clock, rewarding accuracy and letting skilled players extend their run well beyond the 60-second start.

How does difficulty scaling work?

Every 10 correct answers the number range increases automatically, so problems get harder the better you do.

Where is my high score saved?

In your browser's localStorage — it persists across sessions on the same device but is not synced to any server.
