Simple Hex: A Two-Player Connection Game

Simple Hex is a captivating two-player connection game with straightforward rules, making it easy to learn but challenging to master. Players choose red or blue and take turns coloring empty cells on the game board. The objective is to create a connected path of your colored cells linking opposite sides of the board. The first player to complete this connection wins.

Game Modes:

The game offers several modes:

• Play with AI: Challenge yourself against three AI difficulty levels (easy, medium, hard). The AI can play as either the first or second player.
• Play with Friends: Compete against a friend using separate devices.
• Pass & Play: Enjoy local multiplayer gameplay on a single device.

Game Features:

• Undo Button: Regret a move? The undo button allows you to revert your last move(s). (Note: This feature is not yet available in AI mode.)
• Steal Move: To balance the inherent first-player advantage in Hex, the second player can choose to switch positions with the first player after the first move is made. This forces the first player to make a strategic opening move that doesn't guarantee a win. (Not available in AI mode.)
• Multiple Board Sizes: Choose from 7x7, 9x9, and 11x11 boards for varying levels of complexity and playtime.

AI Algorithm:

The AI in this version utilizes a "stable" unbounded best-first minimax game technique. For more details on the algorithm and its performance improvements, please see: https://www.linkedin.com/in/nsvemuri/ We extend our gratitude to interns Saatvik Inampudi and Shoheb Shaik for their contributions to the AI algorithm's performance enhancements.
