Card Price Blitz

You see 20 real sports cards one at a time, each with a price threshold (like "Is this card worth OVER or UNDER $100?"). You have 60 seconds total to answer all 20. Correct answers earn 50 base points plus streak bonuses — the longer your streak, the higher the multiplier (up to 3x). Your final score determines your letter grade from S (perfect) to F.

Each card gets a threshold near its actual estimated value to make the decision challenging. For example, a card worth $150 might get a threshold of $100 or $200 — close enough that you need genuine card knowledge, not just wild guesses. The thresholds vary by card to keep every round interesting.

Every consecutive correct answer increases your streak multiplier: 1x for the first correct, 1.5x for 2 in a row, 2x for 3 in a row, 2.5x for 4, and 3x for 5+. One wrong answer resets the streak back to 1x. This means confident, accurate answers are rewarded more than cautious guessing.

Yes. The Daily Challenge uses the same 20 cards and thresholds for everyone on the same day, so you can compare scores with friends. The Random mode gives you a fresh set of cards each time for unlimited practice. Both modes track your best scores separately.

Grades are based on your total score out of a theoretical maximum of about 3,000 points (20 correct at 3x streak). S grade requires 2,500+, A needs 2,000+, B needs 1,500+, C needs 1,000+, D needs 500+, and below that is F. The time bonus (remaining seconds x5) rewards faster players.
