SUMI FAQ
Is SUMI free to play?
Yes — SUMI is free on ClassPlay, like every game here. It opens in a regular browser tab with no downloads, no installs and no account, so it is ready the moment the page loads.
Can I play SUMI on a school Chromebook?
Yes. ClassPlay games are picked to run well on school Chromebooks: they load in Chrome, ask for very little from the hardware, and use simple keyboard, mouse or touch controls. Nothing needs to be installed first.
Is SUMI appropriate for the classroom?
ClassPlay only lists games we would be comfortable seeing on a classroom screen — no shooters, no horror, no zombie titles. Every game page shows its category, a plain-language description and the controls, so a teacher or parent can see exactly what it is before anyone presses play.
Does SUMI work on phones and tablets?
SUMI plays in any modern mobile browser, but it is most comfortable with a keyboard and a larger screen, such as a Chromebook or laptop. The fullscreen button above the game gives it more room.
