How to play

You get 60 seconds and 3 lives. Factor differences of squares, perfect-square trinomials, and sums/differences of cubes — and spot the ones that are prime. Type like (3x+4)(3x-4) or prime.

• 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 the correct answer with a short explanation.
• 3Questions ramp up: the first 6 are easy, the next 8 are medium, then it is all hard. The game ends at 0 seconds or 0 lives.
