For schools and network administrators

What it is, technically

A website. Every game is one HTML5 page rendered inside an iframe: no plugin, no installer, no extension, no executable, no WebRTC, no microphone or camera access. Nothing is written to the machine beyond ordinary browser storage. It runs on a locked-down Chromebook the same way it runs anywhere else.

Domains to allow

• mavagames.com — the site itself and its API.
• html5.gamemonetize.co — the frames the games are served from.
• api.gamemonetize.com and img.gamemonetize.com — the distributor's SDK and the thumbnails.

That list is not complete and cannot be. A minority of games are hosted on their own developer's domain and loaded through a wrapper, so they will reach hosts we do not control and cannot enumerate in advance. If your policy is strict allow-listing rather than block-listing, expect some games not to load, and that is the honest answer rather than a promise we would have to break.

Bandwidth, measured

We open games in a real browser and record what they transfer. Across 2,417 games measured so far: the median game downloads 6.5 MB, nine in ten stay under 39 MB, and the heaviest we have found is 147 MB. Plan for a classroom of thirty opening different games at once accordingly — the median is a web page with a video on it, the tail is not.

Advertising, and what we do about it

We serve no advertising of our own. The boxes marked «Advertisement» load nothing.

The games do. They come from a distributor and may show ads inside their own frame, under their policies rather than ours. Measured in the same pass: a median of 3 advertising requests in the first twelve seconds, nine in ten under 6, and a worst case of 52. Two things we have changed on our side: the game frame is not created until a pupil presses Play, and we no longer grant it permission to start audio by itself, so a classroom does not fill with sound from a page nobody has touched.

There is no way for a pupil to talk to anyone

This is usually the deciding question and the answer is architectural, not a setting. There is no chat, no comments, no private messages, no public profiles, no username field and no image uploads anywhere on this site. There is no surface where one person can leave text that another person reads. We do not intend to add one.

Accounts

Optional, never required, and restricted to ages 16 and over. Nothing on the site is behind a sign-in. An account only carries a pupil's own history between devices; it grants no communication ability of any kind. See the page for parents for what is stored.

What we cannot promise

• That every game is age-appropriate. We curate and we exclude, but the catalogue is 13,337 games and our filters are human.
• What advertising appears inside a third-party frame at a given moment.
• That a strict allow-list will load every game, for the reason above.

Ask us directly

If you need something specific for an approval process — a fixed list of hosts for a given set of games, a restricted subset of the catalogue, or written answers for a data protection assessment — email [email protected]. A real person answers, and “no” is an answer we are willing to give.
