Answer quickly to pull the rope!

How to play

  1. Start the match and solve the displayed math problem.
  2. Submit correct answers to pull the marker toward your side.
  3. Reach your end of the rope before the bot reaches its end.

Match rules and scoring

  • The rope starts at the midpoint, with both sides equally balanced.
  • A correct answer moves the marker 12% toward your side and adds one point.
  • A wrong answer moves it 8% toward the bot and reveals the correct result.
  • The bot pulls 5% every 2.5 seconds while a match is active.
  • The round ends when the marker reaches either end of the rope.

Arithmetic covered

Each round generates addition, subtraction, and multiplication questions using whole numbers from 2 through 13. Subtraction questions keep the larger number first, so answers are never negative. The changing questions train quick recall without requiring a separate worksheet or timer.

Accuracy matters, but speed changes the match: waiting gives the bot more time to pull. Try to improve your score across repeated rounds while keeping mental calculations correct.
