These are games played amongst two or more people via email. The exact rules (and the exactness of said rules) are best negotiated between players.

Word Furrows

Each person emails the other with a list of 5-7 delicious words. Then each person uses the received words as a prompt, trying to use all the words in the list as they are writing.

Cojones

Each person agrees to produce a spew of writing — un cojon — every day. If one person lapses, they owe the other person $1. If they lapse again the next day, they owe the other person $2, then $4 (the amount doubles each day they don’t write).
