I have posted about computer solution of the card game “24s”. To explore the new social media API interfaces in Mathematica 10, I have created 24s Bot, which seeks to play 24s. You can tweet four integers in the range 1..10 to it and it will let you know if they can be used to make 24. It will also respond to any Twitter messages with the hashtag #24s, and it may at some point in the future respond to other sorts of messages as well.
