Card Chain

You start with one random card. Then you pick from 4 options — each shares at least one attribute (sport, decade, value tier, or player) with the current card. Pick the right connection to extend your chain. The longer your chain, the higher your score. You have 90 seconds to build the longest chain possible.

Four connection types: Same Sport (both baseball, both hockey, etc.), Same Decade (both from 2020s, both from 1990s), Same Value Tier (both $5-$24, both $100+), or Same Player (different cards of the same player). The connection type is shown with a colored badge when you select.

Base points: 10 per link. Streak bonus: consecutive correct picks multiply your score (2x after 5, 3x after 10). Speed bonus: faster picks earn more points. A perfect chain of 15+ links earns an S grade. The daily challenge uses a fixed seed so everyone gets the same starting card and options.

Daily mode uses a date-based seed — everyone gets the same starting card and option pool that day. Compare scores with friends. Random mode generates unique games each time for unlimited practice.

If you pick a card with no valid connection to the current card, the chain breaks and the game ends. Your final score is based on chain length, speed, and streak bonuses. You can always see which connections are valid before picking.
