How does the game work?

It's a tug-of-war math game! Two teams stand on opposite sides of the whiteboard. Each team gets their own math problem to solve. Every correct answer pulls the rope toward that team. The first team to pull the rope past the finish line wins!

What math topics does it cover?

Addition, subtraction, multiplication, and division, or any combination. You can also choose between easy, medium, and hard difficulty to match your class level.

Do I need to create an account?

No. Just open the link and play. There are no accounts, no downloads, and no personal data collected.

Does it work on interactive whiteboards?

Yes! It's built specifically for them. The game supports multi-touch so both teams can tap answers at the same time on the same screen. Tested with SMART Board, Promethean ActivPanel, ViewSonic ViewBoard, and standard projector setups.

What grade levels is it suitable for?

Tug of Math is designed for K-6 students (ages 5–12). Teachers can choose from three difficulty levels, use official grade-specific problem sets, or browse community-created sets tailored to specific curricula. Available in 13 languages.

What devices and browsers does it work on?

It works on any modern browser (Chrome, Edge, Safari, or Firefox) on interactive whiteboards, tablets, laptops, and Chromebooks. Compatible with SMART Board 6000/7000 series, Promethean ActivPanel, ViewSonic ViewBoard, and all Chromebook models. No installation required.

Can two players play at the same time?

Yes! Both teams play simultaneously on the same screen. Each side has its own number pad and math problem, and multi-touch means both teams can tap answers at the exact same time. No waiting for turns, it's a real-time race.

Do students need their own devices?

No, that's the whole point. Tug of Math runs on one screen for the whole class. No Chromebook cart, no "everyone log in," no troubleshooting tablets. Just open it on your whiteboard, projector, or TV and your class is ready to play.

How do I set up a game for my class?

Open tugofmath.app, choose your math operations, difficulty, and points to win, then hit play. Split your class into two teams and you're good to go. The whole thing takes under 30 seconds. No accounts, no app installs.

Can I customize the math problems?

Yes. You can select which operations to include (addition, subtraction, multiplication, division), set the difficulty level, and even create your own custom problem sets with specific numbers you want students to practice.

Can I use it for times tables practice?

Yes! Set the operation to multiplication and choose your difficulty level. Tug of Math is perfect for daily times tables drills. Students practise their multiplication facts in a fun, competitive format with the whole class involved.
