Every maths lesson, island, animal and report stays free forever. Supporter buys decorations, not learning.

You'll need paper and a pencil for sections 3 and 4. No calculator.
On a wrong answer or a long hesitation, don't correct — just tap the button and move on cheerfully. You're mapping gaps, not teaching tonight.
5 sections, about 30–40 minutes. You can stop after any section — progress is saved, and you can continue tomorrow.

Regne is a free daily math practice app for kids aged 5–16. Every age group gets its own complete voyage across Indonesia, Sumatra to Papua — seven islands of age-appropriate maths, each home to a real animal found only there. An adaptive engine repeats what you find hard until it's automatic, with fresh numbers every time.
No ads. No accounts. No tracking. Nothing you do here leaves this device — progress is saved in this browser only. Use the same device (add this page to your home screen!) so nothing is lost.
