How to play

• A round lasts sixty seconds.
• Pick the correct answer out of four as fast as you can.
• Right answers in a row build a multiplier; a mistake resets it and costs three seconds.
• The faster you answer, the larger the numbers become.
• The score is points, not sums solved — speed and streak are what count.

Tips

• Estimate the last digit first: it often rules out three answers at once.
• For multiplication by nine, take ten times the number and subtract it once.
• Do not stare at a hard one; a wrong answer costs three seconds, hesitation costs more.
• The streak multiplier matters more than any single answer — protect it.
