Percent Market
You run the shop: set the discounts, ring up the tax, and keep customers happy. Every pricing decision is percent math — against the clock.
How to play
You get 60 seconds and 3 lives. Each customer brings a pricing puzzle —
sale prices, tax totals, tips, price gains,
successive discounts, and simple interest.
Type a dollar amount like 64.80 (the $ is optional).
- 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. Puzzles start single-step, then ramp to discount-then-tax combos and interest.
