You might be right on 23 and 25.

I used to play sunday lunchtimes with these old boys in the pub. They played so fast you wouldnt believe it.

They would have none of that '19' scoring though. They claimed 'competition' scoring was not 'traditional'.

I thought they showed me how every score but 19 could be got but maybe 19 was just the lowest that couldn't as I cant work out how to get 23 or 25 now! 'NINETEEN' was what they used to shout.
They new every score without needing to count. By the time Id got my cards turned over the guy had already pegged mine - and if you called the wrong score you got hung, drawn & quartered.

No-one seems to play the game here anymore - I tried to introduce friends but no interest. During the war, my late father was ship champion. The lads had him a board made for his birthday in Malta - Somewhere I still have it with the original matchsticks they used.
