In my copy the competition for the washing machine is on Page 43 which although it isn't numbered is opposite page 42 on which is the Pieceword puzzle .
It says enter on page 44 and you quite right ..there is nowhere to write the answer !
The only solution is to email your answers .
I always email my RP answers so I will just type it into my email.
You stand just as good a chance as you would with with posting your entry as I have won a couple of times . Good luck
Happy Christmas.
