Classroom.io

Classroom.io is a multiplayer idle clicker set in one shared classroom. Every player sits at a desk in the same room, earns Brainpower (BP) over time, buys school-themed generators ranging from pencil stubs to galaxy brains, and competes on the chalkboard leaderboard.

Buy upgrades, graduate to higher grades for permanent Gold Stars, and work with the whole class toward shared goals. Throw paper airplanes to steal BP from other players, but watch out during teacher patrols! Random room events like pop quizzes, substitute teachers, and class goals keep the room lively.
