How it works

1Create a duel by choosing a mode: a specific times table, or timed grade-level practice questions.

2Share the generated code with a friend, or enter a code someone sent you.

3Both players answer the same 10 questions, racing against each other and the clock.

4Whoever answers more correctly (and faster) wins the duel.

Worked example

In "times table of 7" mode, one question might be 7 × 8 — the faster correct answer between the two players scores the point.

Frequently asked questions

Do both players need to be online at the same time?

Yes, it's a live match — the challenge waits for the other player to join, then it starts in real time.

Do the questions change every duel?

Yes, a fresh set of 10 questions is generated for every new duel.

What happens if I lose?

Nothing is lost except the round — you can create a new duel right away and try again.

For teachers and parents

Standard: Multiplication fluency and problem solving (Common Core, Grades 3-4) (3.OA.C.7, 4.OA.A.1).

In the classroom: Great for quick pair practice in class — pair up two students on the same times table and let them race.

At home: A fun way to practice with a sibling or a friend at a distance instead of practicing alone.
