Gameplay

Wikigacha is an online gacha trading card game. The player is able to open packs that grant them multiple cards. Each card is based on an article from an edition of Wikipedia corresponding to the language the game is played in, such as English Wikipedia or Japanese Wikipedia. Each card has an attack (ATK), defense (DEF), and rarity values, which are determined by that article's Wikipedia statistics.

Rarity is determined by the article's quality assessment ranking, attack is based on how many pageviews the article receives multiplied by its rarity, and defense is based on how long the article is. Rarer cards are given flavor text; the text is not from Wikipedia and is generated by a large language model. For every 10 packs the player opens, they are given a special gold pack which guarantees them cards with higher rarities. Clicking a card also redirects the player to the associated article.
