These two programs are about putting pieces of a text in order. In SEQUITUR you see the title of a text and the first line. Below are three possible continuations, all from the same text. Pick the one you think should come next and it will be added, and then you get three more possibles, and so on until the story is complete. (The program was first written in 1990 and this new version still in development)
ADDENDA is a new game (Summer 2026) which works similarly, but this time you see three texts and one word which you have to add to the right text.
All the texts are quite short, less than sixty words, and we are building up a range so that there is plenty of variety of styles and subjects.
Here is a French version: ADDENDA (French)
Here is a German version: ADDENDA (German)
I hope soon to be adding versions in Italian and Spanish.
And here, just for fun, is a version with the same text in English, French and German.
