Mark's spelling maze 'u'

The letter 'u' has a long form as in 'tube', but this is usually spelt with a second vowel letter (in this example, the 'e' at the end). A single 'u' may be the equivalent short vowel sound as in 'push' and 'pull', but usually it's a different vowel sound altogether - the one found in 'up'. But in some accents 'push' and 'up' have the same vowel sound. The maze allows for this possibility. but it leads to a dead end. Good luck!
