Frequently Asked Questions
How does Card Auction Showdown work?
You start with a $500 budget and compete against 3 AI collectors in 8 rounds of bidding. Each round, a real sports card comes up for auction. You place your bid, and the highest bidder wins the card. After all 8 rounds, the player with the most valuable collection wins. Strategy matters — spend wisely on high-value cards and let opponents waste money on lesser ones.
Who are the AI opponents?
You face three AI collectors, each with a distinct strategy. "The Whale" bids aggressively on high-value cards. "The Sniper" waits patiently and strikes on undervalued lots. "The Rookie" bids emotionally and inconsistently. Learning their patterns is key to winning consistently.
What happens if I run out of budget?
If your remaining budget is too low to place a minimum bid ($10), you automatically pass on the remaining lots. The AI opponents face the same constraint. Budget management is the core skill — winning every auction is actually a losing strategy because you will overpay.
Does the auction pool change daily?
Yes, the Daily Auction features 8 cards selected from CardVault's database of 5,000+ sports cards, shuffled using a date-based seed so everyone gets the same auction pool. Practice Mode uses a random pool each time so you can hone your strategy.
How is the winner determined?
The winner is the collector whose won cards have the highest total estimated market value — not who spent the most. This means you can win by picking up bargains while opponents overpay. Your profit margin (value won minus budget spent) is also tracked.
