Which characters are checked?
camióncamion does not pass strict mode
tambiénthe final syllable carries an accent
mañanañ is not n
pingüinoü marks a pronounced u
Two answer rules
Strict spelling
á, é, í, ó, and ú must match the answer exactly.
Optional vowel accents
For fluency practice, plain vowels can pass accented vowels. Ñ and ü remain distinct.
Keyboard friendly
Use native composition, long-press input, or the seven built-in Spanish character keys.
Mistakes return
An error enters the mistake notebook and comes back for later independent review.
Why restart the whole word?
This is muscle-memory practice rather than a spelling lecture. Retyping puts the corrected letter back into the complete Spanish form.
