Simple Hex

This two-player connection game, Simple Hex, is easy to learn but hard to master. Players choose red or blue and take turns coloring empty cells on the 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.

The game features "Play with AI," "Play with Friend," and "Pass & Play" modes. The AI offers three difficulty levels (easy, medium, hard) and can play first or second. "Play with Friend" allows multiplayer using separate devices, while "Pass & Play" enables local multiplayer.

An undo button lets you reverse your last move(s), though this isn't yet available in AI mode. A "Steal Move" option gives the second player a chance to switch places with the first player after the first move, preventing guaranteed first-player wins (not available in AI mode). Three board sizes (7x7, 9x9, and 11x11) provide a gradual increase in complexity.

The game's AI uses a "stable" unbounded best-first minimax algorithm. For more information on Hex, visit: https://en.wikipedia.org/wiki/Hex_(board_game)
