Did you try puzzle number 11 (posting 19 Jan 2007). If you did and chose domino 1-blank, working through the steps using blank would have given you a wrong answer.
Go to subroutine reveal to find the culprit
`---------------------------
` One-blank domino
`---------------------------
if domino=10 or domino=0
text 302+tw*1,140,"."
endif
Change it to this
`---------------------------
` One-blank domino
`---------------------------
if domino=10 or domino=1
text 302+tw*1,140,"."
endif
and it should work fine
Sorry about that
