I'm a massive Scrabulous fan (when it works!)
Unfortunately both of the dictionaries are bizarre. For example, I tried the word 'via' - not allowed. However, today, in the space of three moves I was allowed to include the word 'fuck', later extended to 'fucker' and then added the word 'mother' on the front assuming that this was not possible. But yes, indeed it is (and is quite valuable in terms of points).
You can also have 'spiv', 'eh', 'homey' and even 'homeys'.
But can you have 'felch'?
No of course not.
Gah!
(yes, I know I need to get out more)
