Card Auction Sniper

Each session presents 20 timed auctions featuring real cards from our database of 8,700+ sports cards. Auctions run for 45-90 seconds each with live countdown timers. You compete against 5 AI bidders (BidMaster42, SilentSniper, BargainHunter, NewCollector99, and CardSharkPro) who each have different bidding strategies. Place bids manually or use Auto-Snipe mode to automatically bid in the final seconds. Won cards are added to your vault at below-market prices.

Auto-Snipe automatically places a bid for you in the last 5 seconds of any auction where you are not the high bidder. Set your maximum bid amount and the system will bid the minimum needed to win, up to your limit. This mimics real auction sniping services used on eBay and other platforms. It is especially effective against the BargainHunter AI who tends to bid early and stop.

Each AI has a distinct strategy: BidMaster42 bids aggressively throughout the auction. SilentSniper waits until the last 8 seconds to bid. BargainHunter only bids on cards priced well below market value. NewCollector99 sometimes overbids out of excitement. CardSharkPro uses a calculated approach, bidding strategically in the final 20 seconds. Learning their patterns is key to winning.

Daily auctions are seeded by today's date — every user sees the same 20 cards at the same starting prices. This creates a shared daily experience similar to Wordle. Random auctions generate a fresh set of 20 cards each time, allowing unlimited practice. Your balance ($500) and stats carry across sessions via localStorage.

You start each session with $500. Winning an auction deducts the final bid amount from your balance. If you are outbid, your money is returned automatically. The goal is to maximize the total market value of cards won while spending as little as possible. Your win rate, total spent, value acquired, and best deal percentage are all tracked.
