Wikipedia turned into a gacha game: 100M packs opened in 10 days, free forever

A Japanese developer turned Wikipedia into a free web-based gacha game: each card is a Wikipedia entry, with rarity and attack/defense stats derived from the entry's quality, pageviews, and length. No registration required.

Ten days after launch, users were opening over 100 packs per second, totaling 100 million packs. The game is entirely free — packs can't be bought with money — and monetization comes only from ads in exchange for extra packs. A textbook low-cost viral growth case for indie developers.
