• Mobile: Tap the on-screen keypad to enter digits and confirm your answer.

• Master your multiplication tables cold. Most players lose time on 6×7 and 8×9. Drill those until they're automatic — it's the single biggest speed boost.
• Prioritize accuracy over panic. A wrong answer often ends your run faster than a slow one. Breathe, read the whole equation, then commit.
