How to play

You get 60 seconds and 3 lives. Each question asks you to simplify a radical, combine like radicals, or rationalize. Type your answer like 6√2, 7, or (5√2)/2 — then press Enter or Submit.

• 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 (simplifying small radicals) and ramp up to rationalizing and word problems.
