Four-Line Dropper is a game being made for a course project.
Currently it is incomplete, but hopefully the game will have all of the planned
features, such as singleplayer vs. game AI, and networked multiplayer.
All the main features have been implemented.
Also, when playing in "networked multiplayer" mode, if you take too long (about 25 seconds), the AI will take your turn for you.
The source code for the frontend and backend can be found here.
You can play the game here.
