Mental Tank is a free educational artillery game for students in grades 1–12. Every shot has to be earned by answering a question first, so playing means practising. Questions are pitched to each player’s own grade level and cover math, reading, science and world knowledge, from early arithmetic up to precalculus.
It runs entirely in the browser. There is nothing to install, and the whole game can be played without an account.
Signing in is optional and does one thing: it saves progress so it is not lost when a device is closed or swapped. A parent, guardian or teacher signs in once, and each child then gets their own player profile with their own grade level and their own progress.
When you choose Continue with Google we ask Google only for your
name and email address — the standard openid,
email and profile scopes. We use the email address purely to
recognise your account when you come back. Mental Tank cannot read your Gmail, your contacts,
your files or your calendar, and it never posts anything anywhere on your behalf.
There are no adverts, no analytics or tracking services, and no personal information is ever sold or shared. Full detail is in the privacy policy, which also explains how to delete an account and everything in it.
