Drop Four: Connect Four Online is a free multiplayer board game based on Connect Four (also known as Four In A Row).
In this online multiplayer game, you can play against your friends or the AI. If you want to play against the AI, you can set the difficulty level to "easy". If you want to play against your friends, set the difficulty level to "medium" or "hard", and then you can play in "Local" mode or in "Online" mode.
The AI plays the game in the best way possible. It will try to win the game, and if it can, it will drop one disc at each turn. The AI is very good at strategy. The player will have to think about where to place the disc in order to connect four pieces of his own color.
