Common questions

How does Bahaboa pick my problems?

It keeps a skill rating for each operation and picks problems you should get right about 80% of the time. Fast, correct answers raise your rating, and misses lower it a little, so the problems grow with you.

How does a game work?

Each run opens with 5 untimed warm-up problems, then speed mode, where you have 5 seconds per problem. A miss or a timeout in speed mode drops you back to warm-up. Get 5 right to jump back in. Once you've been in speed mode, a miss during warm-up ends the run.

What does the ? key do?

If you don't know an answer, tap ? to flip the card and see it. It takes you back to warm-up, but doesn't end your run.

Can I turn off the sounds or vibration?

Yes, in Settings (the gear on the home screen). Sounds also stay quiet when your phone is on silent.

Can I start over?

In Settings, Retake the level check re-places each operation at the right level. Reset progress erases everything and starts from the tutorial.

Is my progress backed up?

Your progress is saved on your device only. There are no accounts yet, so deleting the app or moving to a new phone starts you fresh.

Does it work offline?

Yes. Everything you need to play is in the app.
