This app, Caro-Gomoku-Renju-FiveinarowgamewithstrongAI, offers a robust platform for playing various five-in-a-row games against a powerful AI or another player. Currently, it supports four common rule sets:

• 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 that isn't blocked on both ends. Lines like XOOOOOX and OXXXXXO are not winning lines.
• GOMOKU Standard: The first player to create an unbroken line of five stones (horizontally, vertically, or diagonally) wins. Lines of six or more stones do not constitute a win.
• RENJU: To mitigate Black's inherent first-mover advantage, additional rules are implemented: Black (X) is prohibited from creating double threes (two separate lines of three unbroken black stones), double fours (two separate lines of four unbroken black stones), or overlines (six or more consecutive black stones).

The app features an exceptionally intelligent AI with adjustable difficulty levels, ranging from easy to extremely challenging. You can also play against a friend. Additional features include zoom functionality, support for two-player mode and AI play, the ability to view the last move and threat lines, and unlimited undo.
