One Billion Users 2025

In One Billion Users, players compete to build the most successful social network. Gain users and attract influencers to build your site while playing cards to slow down your rivals and overcome obstacles. But be careful about which communities you attract — the toxicity they bring with them could hurt your platform!

One Billion Users is inspired by the public domain game Touring which William Janson Roche released in 1906. Touring is a car racing card game, in which you try to go further while putting obstacles on other players. It is considered to be the first “take that!” style card game, which has been imitated and adapted many times since. The most famous such adaptation was 1954’s Mille Bornes, which was so popular that it briefly outsold Monopoly. Mille Bornes is almost an exact replica of Touring with just a few small changes.

We’ve taken the basic mechanics of Touring and adapted it to a favorite topic of ours: social media. Beyond retheming the game, we’ve added new mechanics including: attracting and stealing influencers, balancing user toxicity, and random events (like tech bubbles) that affect all of the players.
