When working out how many SBs there could possibly be in this website I first calculated the product of the number of S-words times the number of B-words.

Right now it’s 1189 x 973 = just over 1.1 million. Quite a lot more than the current total: 2845

Then I looked at how many S-words and B-words that could possibly be listed.

crosswordsolver.org reckons there are 29,800 S-words and 15,268 B-words – nearly 455 million – just short of a semi billion.
