The concept is simple: You're a spy and you have tasks to complete.
Gameplay is also simple... you click on tasks and by chance, either complete it successfully or fail at it. You can also assassinate other spies (fellow Twitter users) by attacking them.
What makes this game different is that it uses Twitter as it's platform. As you grow in experience, complete tasks and assassinate others, Spymaster updates your Twitter status. Your spy also gets stronger based on the number of followers you have (called regular spies). If any of your followers play the game, they help you become stronger!
One of the drawbacks of the game is that you are rewarded for how many tweets you send out: completing tasks, assassinations, etc. This can be seen as spam by a lot of your followers. To resolve this, I've created another Twitter account, for the sole purpose of playing Spymaster.
Currently, the game is in private beta only. So if you want an invite, follow twitter.com/jerolinspy, and I'll invite you as soon as I can.
