What Ankhdase tracks in world & science

- US states
- US capitals
- Continents & oceans
- Countries & flags
- Solar system

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.
