Tizbin is a Persian letter-recognition game for grades 1 and 2. Today's letter sits at the top; squirrels pop up holding word signs, and the child taps only the squirrels whose word contains that letter.

• 120 levels: 92 for grade 1 in the order the book teaches letters, and 28 for grade 2

• Grade 2: the tricky pairs, same-sound and look-alike letters

• Letters at the start, middle and end of words, and look-alike letters

• Words only use letters already taught by that level

• The child picks their own grade at the start

• A Persian narrator reads every instruction aloud

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

• Works offline after install
