Number Fill · learn words
Hear the number. Fill the blank.
Listen to an English number, look at its almost-complete shape, and choose the digit that belongs in the missing place. Start with 100, then try close calls like 338, 322, and 10,332.
Your browser speaks the whole number. No microphone, audio files, or account is needed. Number Fill is practice, not a test of intelligence or listening ability.
Choose a listening level
Which place should you hold today?
Take a three-level fill-in walk or stay with one range. Every round is untimed, and a written fallback keeps the practice moving when speech is unavailable.
