Recommended rulesets

• 8 columns wide: classic 4-in-a-row has 7 columns, which makes it quite easy for the player who goes first to win the game. With 8 columns, the board doesn't have a middle, and the game is a bit more interesting.
• 4 players in 2 teams, 3 to win: gather 4 players and divide into 2 teams, or play with 2 people and take control of 2 colors each. Moves that help your teammate's next move and being able to postpone blocking a loss provide interesting situations.
• 2 players, 3 columns wide, connect 3 to lose: A fun, odd inversion where you're forcing your opponent into a losing situation in a very constrained space. I added the "connect x to lose" mode after reading about one of the games discovered with Bluecap by Mike Cook. Check out their thread about it or play the discovered game.
