MathBird — maths practice with persistent levels

MathBird is now live — the first game on epotli with a difficulty curve and persistent progress.

How it works:

• 10-question sessions. Hit 60% accuracy and the level goes up; miss it and stay where you are.
• Level 1-2 is addition only. Level 3-4 brings in subtraction. Level 5+ unlocks single-digit multiplication.
• Lifetime score, stars, and current level persist across sessions. A child who plays five minutes a day sees the level number rise over a fortnight.

The deliberate design choice: a bad session is a non-event. The child stays where they are and tries again tomorrow.

Best for ages 5-10. Pairs well with Math Pop — Math Pop for warm-ups, MathBird for the long campaign. (Math Pop was retired the next day; MathBird now covers both jobs.)

Note, 9 September 2026. The specifics above are what shipped on launch day. The game has moved on since: a session is now 5 to 10 questions depending on the level, subtraction arrives at level 4 and multiplication at level 7, and the ladder carries on past level 10 rather than stopping there. The current curve is listed level by level on the MathBird page.
