This app, Caro-Gomoku-Renju-FiveinarowgamewithstrongAI, offers four popular game variations:
- GOMOKU Freestyle: Victory is achieved by forming an unbroken line of five or more stones horizontally, vertically, or diagonally.
- CARO (Blocked Rule - Gomoku+): To win, a player must create an unbroken line of five stones that isn't blocked on both ends. Lines like XOOOOOX and OXXXXXO are not winning lines.
- GOMOKU Standard: Similar to Freestyle, but lines of six or more stones don't automatically win the game.
- RENJU: To balance the inherent advantage of the first player (Black), additional rules are implemented: Black is prohibited from creating double-threes (two separate three-stone lines), double-fours (two separate four-stone lines), or overlines (six or more stones in a row).
The app boasts a powerful AI opponent with adjustable difficulty levels, from easy to extremely difficult. 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.
