How to play

You get 60 seconds and 3 lives. Each question asks you to compute with integers — addition, subtraction (watch the double negatives), multiplication, division, and multi-step expressions. Type your answer as an integer like -13.

• 1A correct answer scores +10 points. Streaks of 4 or more earn a bonus of +2 per streak level beyond 3 — keep the streak alive.
• 2A wrong answer costs 1 life, resets your streak, and shows a short explanation of why the correct answer is right.
• 3The game ends when the timer hits 0 or you lose all 3 lives. Questions start easy (addition and subtraction) and ramp up to double negatives, multiplication, division, and multi-step problems.
