Nikipoo School is 44 learning games for primary school, grades 1 to 6, in math, Farsi, science and social studies. Levels follow each grade's Iranian school books, and a Persian narrator reads every level's instructions aloud.

• 6,979 levels in 44 games, step by step from easy to hard

• Math: mental arithmetic, comparing numbers, and more

• Farsi: letters, building words, sentences, reading

• Science: a hands-on lab (predict, test, conclude), observation and weather games

• Social studies, grades 3–6: the map of Iran, map reading, timelines, the Persian calendar

• Mistakes are never punished; the child is encouraged and carries on

• Coins earned in play buy avatars in the in-game shop

• Themes: the child picks a favourite cartoon hero from 12, and the home screen, games and celebrations take on that hero's colours and world

For parents: several children on one phone, a progress report per child (stars, time, accuracy, where to practise more), a daily time limit, and a parents' area behind a multiplication question. No chat, no sign-up. Works offline after install.
