What Ankhdase tracks in world & science

Questions about world & science on Ankhdase

Are these science games free?
Yes — all 2 are free, run in the browser, and need no download. You can play without an account; signing in only adds saved progress, streaks and badges.
What ages are these science games for?
They span kinder to adult. Difficulty adapts per student rather than per game, so the same activity works across several year groups.
How does Ankhdase decide what to show next?
It keeps a mastery estimate for each of 9 science skills. Questions drift toward the skills a student is getting wrong and away from ones they have already proved, aiming for roughly 80% accuracy — high enough to feel good, low enough to still be learning.
Can I use these science games in a classroom?
Yes. Teachers can create a class, generate student logins in bulk without email addresses, set assignments with goals, and read a class heat map showing mastery per student per skill.
Do they work offline or on a tablet?
Most do. Once a page has loaded, a service worker keeps it working without a connection, and every drag interaction has a tap alternative for touchscreens. Typing activities need a physical keyboard.
