Mark's spelling maze 'o'

A single letter 'o' typically has the same vowel sound as in the words 'top' and 'stop'. But there are plenty of exceptions. For example, look out for a 'magic e' later in the word, for example 'home'. Or if there's a 'y' or 'w' or an 'r' after the 'o'. Of if the 'o' is at the end of a word, for example 'go'. There are some dead ends in this game - words which may contain the 'TOP' sound for some speakers but not for all.
