Cookie Clicker as a race against other people. You pick a nickname, join a random room or create one with a code, set a time limit and a player cap, and then everybody clicks until the clock runs out. Up to ten players, and a ranking screen at the end.
Rooms need somebody to fill them, so it is a game to open with friends rather than one to open alone. The interface is in Portuguese and English by turns. As a solo experience there is a timer, a cookie and a score, and not much reason to stay.
