Facebook used to be not only a social network, but also a platform where anyone could play a variety of interesting games. Games on Facebook appeared around 2008 and quickly gained popularity. There were farms, cafes, zoos, puzzles, and RPG games. Users played every day, invited friends, and competed for achievements. After a few years, the number of players exceeded hundreds of millions. Gradually, popularity declined, but some projects continued to exist in new formats or on mobile platforms. Today, people remember the old Facebook games with nostalgia.
