Red Herrings

Each of the 400 challenge cards features eight, colour-coded clues and five answers. The answers to six of the eight clues will form pairs of homonyms (sounding the same, spelt the same way, but with different meanings). The remaining two answers are the 'red herrings'. They will be homophones (sounding the same but spelt differently and with different meanings). Your task is to identify the two homophones within 30 seconds to score points. Be the only player to find the red herrings and you will score a double win. —description from the designer
