POT
could become
SPOT
but equally
POET POST or PORT.
Yes, it could become POTS but that's a bit boring.
Then I shall fully expect Scurra to use this thread as a puzzle resource.
If it gets boring I might add in another layer whereby you get points for the number of letters you can add in WITHOUT changing the order. But let's see how it goes for a bit first.
I'm starting with
SALE
EDIT Having tried this out, I now realise that a far better version has evolved.
The idea is to make a new word, using the letters of the word posted by the previous person, but KEEPING THEM IN THE SAME ORDER. Thus GREEN might become AGREEMENT. Then that person should post another LINKED word to their new answer, eg NOD. Play passes to the next person, who has to make a new word using NOD but being kept in the same order. E.g. ANDROID This should then be followed by another linked starter word, e.g. ROBOT.
I hope that's as clear as mud.
(one letter per go then post a new word) or you're all being clever devils...
