I like these games, but in this one there are a lot of possible alternatives which could be allowed (other games like this have usually had only one possible answer). For instance, you could have grip, graze, tracing, sinner, brook, tangled, manger... Is there a way of allowing these (and others), I wonder?
Thanks for the quiz - it was fun to do one of these for a change! NigelS and cpgatbyu are right, though: it only works if there's one possible answer for each clue. OWN, for example, has six possible answers: Down, gown, lown, mown, sown and town. If you change the ones that have multiple answers, you'll have a great quiz!
