MathTug is a free collection of interactive math games and puzzles for students, families, and classrooms. Designed by educators, it turns arithmetic practice into playful challenges that encourage students to learn through competition, problem-solving, and quick thinking. Its flagship game, Math Tug of War, lets two teams solve questions simultaneously, with each correct answer pulling the rope toward their side. Teachers can choose levels from nursery through high school, name the teams, and play on classroom displays.

The site also offers a daily timed arithmetic sprint, number and logic puzzles, and games covering topics such as counting, odd and even numbers, fractions, equations, multiplication, primes, and Sudoku-style grids. Activities are organized into difficulty tiers for different ages and skills. MathTug is designed to work on phones, tablets, computers, projectors, and interactive whiteboards. The service is free to use, requires no signup or installation, and offers classroom-ready play without advertisements or in-app purchases. It aims to make math practice accessible and engaging for learners at home or school.
