Co Caro - Gomoku - Renju

Caro-Gomoku-Renju: A Five-in-a-Row Game with Powerful AI

This app offers four popular five-in-a-row game variations:

• Gomoku Freestyle: The first player to achieve an unbroken line of five or more stones horizontally, vertically, or diagonally wins.
• Caro (Blocked Rule - Gomoku+): Victory requires an unbroken line of five stones, but lines blocked on both ends (e.g., XOOOOOX) don't count. This rule is especially popular in Vietnam.
• Gomoku Standard: Similar to Freestyle, but overlines (lines of six or more stones) don't win the game.
• Renju: To balance the inherent advantage of the first player (Black), Renju incorporates additional rules restricting Black's moves:
  • No Double Threes: Black cannot create two separate three-stone lines.
  • No Double Fours: Black cannot create two separate four-stone lines.
  • No Overlines: Black cannot create a line of six or more stones.

The app features an exceptionally strong AI opponent with adjustable difficulty levels, ranging from easy to extremely challenging. You can also play against a friend.
