Wikicards

Wikicards is a free-to-play collectible card game for iOS and Android that turns Wikipedia articles into cards. Each card is a real article, from planets and dinosaurs to historical figures and monuments, and its rarity depends on how widely the article is read, across six tiers from Common to Legendary. Players open a free booster of five cards every 15 minutes, organize their collection in folders, showcase their best cards on their profile and read the linked Wikipedia article from any card. Duplicates can be sold at auction on a player-driven market using the in-game currency, WikiFlouz, or traded directly with friends, and five cards of the same rarity can be fused in the Lab for a chance at a rarer one.
